Not for crappy weather.
The light weight of this tent along with a couple solid reviews led me to purchase this for an 8 day backpacking trip in Wrangell St Elias...Have used 3 season tents for years while backpacking in AK and have never had an issue. Not so with this tent. The fly design means you have to have 8 guy lines fully staked out to not have the fly touching the tent, which even though doesn't necessarily keep moisture from the inner tent. And even if this tent is fully staked out it doesn't do great at handling wind...the wind goes under the fly & through the tent, which is noisier than other tents I've owned, and results in the tent poles flexing a good bit. Our seventh night in this tent the wind actually caused one of the poles to bust in half, collapsing our tent at 4am, and the bent pole tearing a large hole in the fly. I'm sending the tent back to Big Agnes to see what/if they'll cover the damage. This tent would work great for ideal summer weather camping, and I applaud Big Agnes for going super light, but this tent is not cut out for wet, windy, or cold weather, at all.
