Thank you for viewing m(_ _)m I purchased this in January 2024 and used it about 5 times during the winter for work. The product's performance is excellent and I loved it, but I am selling it due to a job change. It was only used on top of a cot or mat, never directly on the ground. It was only used as a sleeping bag cover, not directly on skin or clothing. After use, I immediately air-dried it, so I believe the maintenance and storage conditions are good, but please understand that this is a used item that has actually been used before purchasing. Thank you. I am a fan of finetrack, so I have other items listed as well. Please feel free to ask about combined purchases or any questions you may have.
