Underwood Aggregator Tent Footprint 86.6 x 59.1 in Waterproof Ultralight Groundsheet — 210T PU3000mm, Heavy-Duty Grommets

Underwood Aggregator's Tent Footprint is an ultralight, waterproof groundsheet designed to protect your tent floor from moisture, abrasion, and punctures while staying compact for backpacking.

Built from 210T ripstop fabric with a PU3000mm coating, this 86.6" x 59.1" (220 x 150 cm) tarp acts as a durable barrier between your tent and rough or wet ground. At just 10.16 oz (288 g) and folding down to fit inside its included carry bag, the footprint balances light weight with serious protection. Heavy-duty grommets and taped seams increase longevity and make staking straightforward so your shelter stays put through changing conditions.

How does this footprint keep my tent dry on wet ground?

The fabric's PU3000mm waterproof coating prevents water from soaking through while the ripstop weave resists tears caused by rocks and roots. Sizing the tarp slightly smaller than your tent's floor ensures the tent edges overlap and block water entry between layers.

• 210T ripstop polyester with PU3000mm coating for reliable water resistance
• Taped seams to stop seepage at stitch lines
• Smaller-than-floor size prevents runoff from channeling under the tent skirt

Is this tarp lightweight enough for backpacking and ultralight trips?

Yes—at 10.16 ounces (288 grams) this footprint is optimized for packable protection without adding bulk. It compresses into the supplied carry bag so it tucks into a backpack side or an external pocket easily.

• Compact folding design fits in small pack compartments
• Low weight minimizes impact on basepack weight calculations
• Simple shape reduces setup time and complexity

How does the footprint attach and stay put under my tent?

Reinforced, heavy-duty grommets at the corners allow you to stake the footprint in place, preventing shifting and bunching beneath your tent. The taped seam edges also help the tarp maintain shape and avoid fraying during repeated use.

• Corner grommets for secure staking (stakes not included)
• Reinforced edges and taped seams for long-term durability
• Slightly reduced dimensions than tent floor to ensure proper overlap

Can I use this tarp for things other than a tent footprint?

Absolutely. The rugged waterproof material and reinforced construction make this tarp a versatile outdoor tool—use it as a picnic mat, gear protector, beach sheet, hammock underlay, or emergency ground cover. Its light weight and packability suit many on-the-go situations.

• Works as picnic mat, beach sheet, or gear barrier
• Handy as an under-hammock or emergency shelter liner
• Easy to rinse and dry for repeated outdoor use

Who is this for: Outdoor enthusiasts who want a reliable, lightweight groundsheet that adds meaningful protection without heavy bulk. Hikers, weekend campers, festival-goers, and anyone who needs a compact waterproof layer under a tent or for ad-hoc outdoor use will find this footprint useful. Backcountry travelers who prioritize low weight but won’t compromise on durability will especially appreciate the reinforced grommets, taped seams, and tear-resistant fabric.
