10 Best Tent Underlay Tarps 2026 in the United States

The Clostnature Tent Footprint is a solid choice if you're looking to protect your tent floor from wear and moisture. Made from durable ripstop polyester with a waterproof coating, it offers reliable protection against wet and rough ground. Its size (108" x 84") fits well for 4-6 person tents, making it versatile for small to medium camping setups.

Weighing just 16 ounces, it’s light enough to carry without much extra bulk and packs down compactly into a small drawstring bag, which is convenient for backpacking. The heavy-duty material performs well in keeping water out. One minor drawback is the lack of mentioned grommets or tie-down points, which means you may need to secure it with stakes or weights yourself when using it as a standalone tarp.

Besides serving as a tent underlay, it also doubles as a sunshade, picnic mat, or hammock rain fly, adding to its usefulness. If you want a straightforward, durable, and lightweight groundsheet that protects your tent and offers multifunctionality, this footprint covers those needs nicely.

The Clostnature Tent Footprint is a reliable and practical ground tarp designed to protect your tent floor from wear, moisture, and dirt. Made from durable ripstop polyester with a waterproof coating, it offers strong resistance to water and rough ground, helping extend the life of your tent. Its size of 118 by 118 inches fits well with medium to larger tents, such as the Clostnature 6-person tent, providing ample coverage.

The 210T polyester material provides a good balance of sturdiness without adding too much weight. It also includes grommets or tie-down points, allowing you to secure it tightly and prevent slipping. Aside from serving as a tent floor protector, this footprint doubles as a sunshade, beach mat, or hammock rain fly, offering versatility for different outdoor uses.

This footprint is a solid choice for campers seeking a tough, waterproof underlay that’s easy to pack and versatile enough for various outdoor activities.

The CORE Outdoor Tent Footprint is a well-sized tarp designed specifically for large 10-person tents, making it a great choice if you own one of the compatible CORE tent models. Made from polyethylene, it offers solid protection against moisture, sharp objects, and ground insects, helping extend your tent's life and keeping the interior dry. Its dimensions (about 13.5 by 9.5 feet) match well with large tents, ensuring full coverage.

While it is water resistant rather than fully waterproof, this level is usually sufficient for most camping conditions when used as an underlay. The tarp is fairly lightweight and packs down compactly, which is convenient for carrying and storage. Setup is user-friendly thanks to elastic loops on all four corners that help secure it tightly under the tent, though it lacks metal grommets that some campers prefer for extra durability and tie-down options.

Additionally, its multipurpose nature means you can use it for other outdoor activities like picnics or tailgates. However, since it’s polyethylene, it might not be as durable long term as heavier-duty fabrics. Also, there’s no UV protection, so prolonged sun exposure could degrade it faster. If you need a straightforward, budget-friendly footprint tailored to large CORE tents and value easy setup and packability, this tarp is a practical choice.
