Sea to Summit Telos Lightfoot Footprint vs Big Agnes Copper Spur UL2 Footprint

The Lightfoot wins because Sea to Summit publishes the fabric, the waterproof rating and the attachment hardware, and states that the shape is designed to stop water pooling, which is the failure this product exists to avoid. The Big Agnes is the lighter choice if you own a Copper Spur and want the Fast Fly pitch.

Sea to Summit Telos Lightfoot Footprint

Buy it

The only footprint here that publishes its fabric, its waterproof rating and the fact that its shape was drawn to stop water pooling.

• 68 denier waterproof polyester with a stated 1200mm waterhead rating, which is a real number where most competitors give none.
• Sea to Summit states it is sized to avoid water pooling and collecting dirt, naming the failure mode directly.
• Strong hypalon perimeter attachment points, circular-bartacked so they flex without tearing out.
• Enables a Fly Only pitch, so the tent body can stay home on ultralight trips.

• 267 grams for the TR2 size, heavier than the Big Agnes equivalent.
• Model-specific to the Telos range, so it is useless on any other tent.
• Premium price for what is fundamentally a shaped sheet of coated fabric.

Big Agnes Copper Spur UL2 Footprint

Buy it

A stated 141 grams, cut for one tent, and the key that unlocks pitching the fly without the tent body.

• 141 grams, the lightest footprint in this comparison.
• Enables the Fast Fly configuration, which Big Agnes specifies as footprint, fly, poles and stakes with the tent body left behind.
• Cut specifically for the Copper Spur UL2, so the edges sit inside the tent floor where they belong.
• Also listed as compatible with the Copper Spur UL2 Bikepack, so one footprint covers both versions.

• Big Agnes publishes no denier and no hydrostatic head for the fabric.
• Fits two tent models and nothing else.
• The Fast Fly pitch needs the poles and fly from the same tent, so it is not a standalone shelter.
