I've used a Big Agnes Copper Spur UL3 for 4 full Muir Trails (two of them aborted yo-yo's), about 80 nights in the Sierra, experienced everything from no wind and calm to 7 inches of slush and hail, 60mph winds, etc. Love the tent. Never missed a beat, nothing has failed, not even a single stitch in the material has failed. Poles snap together like new.fishhunter wrote:Well you might be leery of another Big Agnes but just had a new B/A Copper Creek UL2 out on first trip, and it survived a 5 hour hail/rainstorm with no problems. I really light the weight and size of it, expected to be less than impressed with durability (e.g. snagging zippers, etc.) but was as good as my previous Kelty Gunnison 2 at half the weight.

Good ventilation, easy setup, light (5 pounds for a roomy 3 person tent, comes in 1 and 2 person sizes too). The poles almost assemble themselves, plenty of guy-out lines, functional zippers, room for gear on both sides, storage space in small hanging pocket. The tent material is too thin to get much shade should you need it in the bright son, so we throw our tyvek over the top of it.
drawbacks: even on ebay, this was almost $300, while REI wants a ridiculous $500 for it. Made in China.
My other single person BA tent is poorly designed. I never use it. Going on ebay. So it's probably a hit and miss with their stuff.
