Sea to Summit Telos Lightfoot Footprint vs Big Agnes Copper Spur UL2 Footprint
Which should you buy? Our verdict on both, pulled from our full The Best Tent Footprints: 4 Compared (and One to Skip) comparison.
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 itThe only footprint here whose maker says its shape was drawn to stop water pooling, with fabric, waterproof rating and hardware all published.
- 68 denier waterproof polyester with a stated 1200mm waterhead rating, published alongside the attachment hardware.
- 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.
- 243 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.
- Its 1200mm waterhead rating is lower than the figures Big Agnes and NEMO publish for their footprint fabrics.
Big Agnes Copper Spur UL2 Footprint
Buy itA stated 148 grams, cut for one tent family, and the key that unlocks pitching the fly without the tent body.
- 148 grams, the lightest two-person 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 and UL2 mtnGLO, so one footprint covers several versions.
- Its 30D nylon ripstop is thinner than the Sea to Summit's 68D or NEMO's 75D fabric.
- Fits the Copper Spur UL2 family and nothing else.
- The Fast Fly pitch needs the poles and fly from the same tent, so it is not a standalone shelter.
