Will the Copper Spur UL2 Footprint Fit the Copper Spur UL2 Bikepack and Fast Fly?
Yes — this footprint is compatible with both the Copper Spur UL2 and the Copper Spur UL2 Bikepack. Because it is cut exactly to the Copper Spur UL2 floor, it attaches cleanly, covers the full floor, and supports the Fast Fly configuration: pitch the footprint with the tent fly, poles, and stakes while leaving the tent body at home for a lightweight shelter.
How to Attach a Big Agnes Footprint to the Copper Spur UL2
Lay the footprint under the tent floor and secure it using the Tiplok and compatible attachment points on the tent body, matching the corner positions to the tent's pole tips for a taut, wrinkle-free fit. The Tiplok tent footprint compatibility means corners integrate directly with the tent's hardware — no generic grommet fiddling required.

Selection Criteria & Comparisons
Why the Genuine Footprint Beats a Generic Tarp
Compared to a hardware-store tarp, this footprint matches the Copper Spur UL2's exact floor dimensions, adds minimal weight for backpacking and bikepacking, integrates with Tiplok attachment hardware, and enables Fast Fly mode — a generic tarp does none of that. Compared to buying a heavier double-wall tent, the footprint plus fly Fast Fly setup saves real pack weight on fair-weather trips.
