Seek Outside Redcliff Used about 5 times over 3 years. While it hasn't been used much, there are two small holes from sparks when using a wood stove. See images 6, 7, and 8. Repaired from both sides with a silnylon patch. Since the material is silnylon, there is no degradation such as hydrolysis. I think it can still be used safely for a long time. Additional information: I found the separately sold storage bag, so I will include it. The set includes: Tent body Dedicated carbon poles Silnylon storage bag Separately sold storage bag (last photo)
