Therm-a-Rest NeoAir XLite Regular size. Purchased new in February 2023 at Kojitsu Sanso. Used approximately 5-6 times in the dead of winter. The repair patches were taken out and stored with the emergency kit, so the original bag is not available. (They have not been used.) I inflated it for about a week before listing it, and there was almost no air leakage. The lettering on the WingLock valve was worn from new... I think it will be useful in the coming season and in winter. This is used outdoor gear, so please understand and consider purchasing.
