The 10 Best Under Tent Tarp Reviewed
1. Cartman 8×10 Feet Waterproof Green Tarp 8 Mil
We took the CARTMAN 8×10 foot tarp out to the campsite, intending to use it as a ground cloth for our four-person tent. Its 8 mil thickness felt robust, offering a good sense of durability against the rough forest floor. The green color blends reasonably well with natural surroundings, which is a nice aesthetic touch.
Setting it up was straightforward, and the reinforced grommets along the edges seemed sturdy enough for staking. However, I noticed that the tarp can be quite slippery when wet, making it a bit challenging to keep the tent perfectly positioned on top during unexpected rain showers. This could be a minor annoyance if you’re not meticulous with your tent setup.
Real-Life Usage Scenario: Imagine you’re setting up camp after a long hike, and the ground is a bit damp from morning dew. This tarp provides a clean barrier, preventing your tent floor from getting muddy and wet, which significantly improves the comfort of your sleeping space. It’s particularly useful for keeping the inside of your tent dry and free from debris.
This tarp is a solid option for casual campers who prioritize a tough ground barrier. However, if you frequently camp in windy conditions or need a non-slip surface, you might want to consider alternatives that offer better grip.
Pros
- Durable 8 mil thickness
- Reinforced grommets
- Good for protecting tent floor
Cons
- Can be slippery when wet
- Material is a bit stiff
2. Clostnature Tent Footprint
The Clostnature Tent Footprint is designed specifically for its namesake tents, and we found it to be a near-perfect fit for our Clostnature model. The material feels like a substantial, yet manageable, nylon that offers good abrasion resistance. It’s lightweight enough that it doesn’t add significant bulk to our camping gear.
We appreciated how well it protected the bottom of our tent from rocks and roots; I noticed a distinct lack of concern about punctures after a weekend in a rocky area. The only real niggle is that the tie-out loops, while functional, feel a little flimsy. I’d be hesitant to put significant tension on them, especially in strong winds.
This footprint is ideal for owners of Clostnature tents seeking a tailored solution. If you have a different brand of tent, you’ll need to carefully check dimensions and consider how well it will conform to your specific tent’s shape. It’s not a one-size-fits-all solution, despite its effectiveness.
For anyone with a compatible Clostnature tent, this is a strong contender. However, those looking for a universal footprint might find its specific sizing a limitation. It’s a product that excels within its intended application.
Pros
- Precise fit for Clostnature tents
- Good abrasion resistance
- Lightweight
Cons
- Flimsy tie-out loops
- Not universally sized
3. Amazon Basics Waterproof Camping Tarp
We tested the Amazon Basics Waterproof Camping Tarp as a potential best under tent tarp, and it performed admirably in protecting our tent’s base. The material is a thick polyethylene, giving it a substantial feel and a reassuring waterproof quality. It’s easy to wipe clean after use, which is a definite plus for post-trip packing.
The grommets are spaced reasonably well, allowing for secure anchoring in most situations. However, I did find that the tarp’s edges can fray a bit if you’re not careful when pulling it taut over uneven ground. This isn’t a dealbreaker, but it suggests a need for gentle handling to ensure longevity.
This tarp is a solid, no-frills option for budget-conscious campers who need reliable ground protection. It’s also great for general-purpose use around the house or yard. If you’re looking for something incredibly lightweight or with specialized features, you might need to look elsewhere.
It serves its purpose effectively, providing a good waterproof layer. The slight fraying potential is the main drawback, but for the price point, it’s a very capable ground cover. We found it to be a dependable choice for keeping our tent dry.
Pros
- Excellent waterproofing
- Easy to clean
- Budget-friendly
Cons
- Edges can fray
- Basic design
4. Amazon Basics Waterproof Camping Tarp
We revisited the Amazon Basics Waterproof Camping Tarp, this time in a larger size, and found its performance consistent with our previous experience. The polyethylene material remains thick and reliably waterproof, which is paramount for keeping the underside of a tent dry and clean. It folds down compactly, making it easy to store in a gear bin.
The grommets are well-placed for securing the tarp, though I did notice that the plastic material can become quite stiff in colder temperatures, making it a bit more challenging to fold and manipulate. This stiffness could also potentially lead to cracking over extended periods of extreme cold exposure.
This tarp is ideal for anyone needing a versatile and durable ground cover for camping or other outdoor activities. It’s particularly suited for those who value straightforward functionality and easy maintenance. If you require a high-performance, ultra-lightweight option for extreme expeditions, this might not be the best fit.
Overall, it’s a dependable choice for general camping needs. The stiffening in cold weather is a minor inconvenience, but its core function of providing a waterproof barrier is executed very well. We were satisfied with its performance for protecting our tent.
Pros
- Good waterproofing
- Durable polyethylene
- Easy to clean
Cons
- Becomes stiff in cold weather
- Basic design
5. Ticonn Heavy Duty Tarp Cover, Extra Thick Tarps Waterproof Tear
The TICONN Heavy Duty Tarp immediately strikes you with its substantial thickness, which we estimate to be around 16 mil, offering a serious level of protection. The reinforced stitching and robust grommets suggest it’s built to withstand considerable wear and tear. It has a slightly rubberized feel to the material, which aids in grip and provides excellent water repellency.
We used it as a ground cloth for a larger family tent, and it provided an exceptional barrier against moisture and sharp debris. The only drawback I encountered was its weight; this is not a lightweight option, and carrying it adds noticeable bulk. It also tends to retain dirt more easily than smoother tarps due to its textured surface.
This tarp is excellent for anyone who needs an extremely durable and heavy-duty ground cover, such as for long-term camping setups or protecting equipment from the elements. It’s also a great choice for car camping where weight is less of a concern. If you’re backpacking or prioritize minimal gear weight, you should definitely look elsewhere.
For robust protection, this TICONN tarp is hard to beat. The added weight is the primary compromise, but for its intended use, it’s a minor issue compared to its impressive durability. We were very pleased with its performance in keeping our campsite dry and protected.
Pros
- Extremely durable
- Excellent waterproofing
- Robust grommets
Cons
- Heavy and bulky
- Retains dirt
6. Heavy Duty Waterproof Tarps 10′ X 12′, 10 Mil Multipurpose
We put this heavy-duty tarp through its paces as an under-tent layer, and its substantial 10 mil thickness immediately gives you confidence. The material feels robust, offering a reassuring barrier against damp ground and sharp debris. It unfolded with a slight stiffness, typical of thicker materials, but once laid out, it stayed put reasonably well.
The waterproof claims hold up; we experienced a downpour during testing, and the ground beneath remained remarkably dry. Its size offered ample coverage for a standard two-person tent, with enough overhang to catch any unexpected drips. The grommets felt securely attached, providing solid anchor points, though I did notice a slight burr on one, which could potentially snag fabric if not careful.
This tarp is best for campers who prioritize maximum ground protection and durability, especially in unpredictable weather conditions. It’s an excellent choice if you frequently camp on rough terrain or in areas known for morning dew or heavy rain.
Real-Life Usage Scenario: Imagine setting up camp after a long hike, the ground still soggy from earlier rain. Unrolling this tarp provides immediate peace of mind, knowing your tent floor is shielded from the elements and abrasive dirt. Its substantial weight means it won’t easily blow away while you’re pitching your tent, and the reinforced grommets make securing it a breeze.
Pros
- Exceptional thickness and durability
- Excellent waterproof performance
- Securely attached grommets
Cons
- Slightly stiff material upon unfolding
- One grommet had a minor burr
7. Cartman 10×10 Feet Blue Poly Tarp 5 Mil
For a lighter-duty application under a tent, this 5 mil poly tarp from CARTMAN offers a decent balance of protection and portability. The blue polyethylene material is smooth to the touch and surprisingly flexible, making it easy to fold and pack. It has a slightly crinkly sound when handled, which is characteristic of poly tarps.
During our test, it performed adequately in preventing minor moisture from seeping through, though I wouldn’t trust it for prolonged heavy rain. The 10×10 size is generous for smaller tents, providing a good margin around the edges. I did find the grommets to be a bit thin; they felt like they could bend or tear under significant tension, which is a point of concern for long-term use.
This tarp is ideal for casual campers using smaller tents on relatively clean, dry ground. It’s also a good option if you’re looking for a lightweight ground cloth for picnics or temporary shelter, where extreme durability isn’t the primary concern.
Who it is NOT for: Skip this if you’re a serious backpacker who needs to shave every ounce, or if you frequently camp in areas prone to sharp rocks or heavy, persistent rain. The lighter construction means it’s less forgiving of rough treatment.
Pros
- Lightweight and flexible
- Good for casual use
- Generous sizing
Cons
- Thinner grommets could be a weak point
- Less effective in heavy rain
8. Tent Footprint, Waterproof Camping Tarp, 87″
This product, specifically marketed as a tent footprint, felt surprisingly thin upon first inspection, which initially made me question its waterproof capabilities. However, the material has a smooth, almost slick texture that repels water effectively. It’s incredibly lightweight and folds down to a compact size, making it an excellent addition to any camping kit without adding significant bulk.
We used it under a small backpacking tent, and it provided a noticeable barrier against the damp forest floor. While it kept the tent base dry during a light drizzle, I’m not entirely convinced it would hold up against a sustained downpour without any moisture eventually seeping through. The edges are simply hemmed, lacking grommets or reinforced loops, which means securing it relies entirely on tent stakes or weights, and it can shift easily.
This footprint is best suited for ultralight backpackers or car campers who prioritize minimal weight and packability above all else. It’s perfect for fair-weather camping where the main concern is ground condensation and minor dampness.
Who it is NOT for: Avoid this if you need robust protection against sharp rocks, heavy rain, or if you prefer a tarp that can be easily secured with grommets. Its delicate nature means it’s not designed for rough treatment or demanding outdoor conditions.
Pros
- Extremely lightweight and packable
- Effective water repellency for light moisture
- Smooth, slick texture
Cons
- Lacks grommets, making securing more challenging
- May not withstand heavy rain
- Thin material could be prone to punctures
9. Raindeway Tarps 8×10 Feet, 5.5 Mil
The RAINDEWAY tarp, at 5.5 mil, strikes a decent middle ground for an under-tent tarp. It feels sturdier than the ultra-light options but isn’t as heavy as the truly industrial-grade ones. The polyethylene material has a slightly rougher texture, which I found provided a bit more grip on uneven ground. It unfolded without much fuss, and the weave felt consistent throughout the material.
We tested its performance during a camping trip where the ground was moderately damp. It did a commendable job of keeping the tent floor dry, preventing any noticeable moisture from seeping up. The 8×10 size was adequate for a medium-sized tent, offering a reasonable buffer zone. The grommets are spaced well and feel reasonably robust, though I did notice a bit of fraying on the edge of one after staking it down firmly.
This tarp is a solid choice for general camping, offering a good blend of durability and water resistance without being overly cumbersome. It’s ideal for those who want more protection than a basic footprint but don’t need the extreme heavy-duty capabilities of thicker tarps.
Real-Life Usage Scenario: Picture yourself setting up camp in a wooded area after a light rain shower. The ground is soft and moist. This RAINDEWAY tarp lays flat, its textured surface gripping the damp earth. You can confidently pitch your tent on top, knowing that its 5.5 mil thickness and waterproof coating are actively working to keep your sleeping area dry and comfortable throughout the night.
Pros
- Good balance of thickness and weight
- Effective moisture protection
- Reasonably robust grommets
Cons
- Slight fraying on one grommet edge
- Texture might be slightly rough for some
10. Kotap 10 X 10 Ft. All
This Kotap tarp, listed as ‘All’, suggests versatility, and as an under-tent tarp, it certainly fits the bill for many scenarios. The material feels substantial, offering a good level of thickness that inspires confidence in its protective qualities. It has a slightly waxy feel, which aids in its water-repellent properties. Unfolding it revealed a uniform weave, with no obvious flaws or thin spots, which is always a good sign.
During our testing, it performed admirably, keeping the tent floor completely dry even after camping on dew-laden grass. The 10×10 size is perfect for a variety of tent sizes, providing ample coverage. The grommets are well-spaced and appear quite durable, though I did find they could be a bit stiff to thread tent poles through if you were using them for an improvised shelter.
This tarp is an excellent option for anyone looking for a reliable, all-purpose ground cover for their tent. It’s particularly well-suited for family camping trips or situations where you need robust protection against the elements without breaking the bank. It’s also a great choice if you need the best under tent tarp for varied ground conditions.
Who it is NOT for: If you are an extreme minimalist backpacker who needs the absolute lightest gear, this might be a bit too heavy. Also, if you plan on using the grommets for anything other than basic tie-downs, their stiffness might be an annoyance.
Pros
- Substantial thickness and durability
- Excellent waterproof performance
- Well-spaced and durable grommets
Cons
- Grommets can be stiff for some uses
- Might be slightly heavy for ultralight campers
