2018 Tarptent Stratospire 1 (silnylon) still in great shape. Double wall with mesh interior. Purchased in 2018 for Colorado Trail thru hike (30 nights) and used sparingly since. Taken care of very well, on trail and off – always stored clean, dry and uncompressed. No holes, leaks, or tears. Great one person tent with lots of interior room and large double vestibules. More pictures available.
