User Review: Big Agnes Copper Spur UL1
I used the Big Agnes Copper Spur UL1 on a 5 day, 40+ mile, backpack trip from Mt. Hood to the Columbia River. It rained continuously the first 2 1/2 days. This little tent kept me completely dry with very little condensation EVEN with elevated humidity levels the entire time.
It had plenty of room for changing and moving around. The vestibule easily fit my pack and boots under it. Considering that it barely weighs more than a bivy or tarp, it is worth the couple of ounces for the comfort it supplies!
Overall, it has been one of my best purchases.
