This is an inflatable sleeping mat from ALPS MOUNTAINEERING. I bought it in the US about 10 years ago. I've used it a few times, and it's a lightweight and good air mat, but ❗️❗️it leaks air❗️❗️ I'm currently busy raising children and don't have much time to use it, nor do I have time to repair it... If anyone can repair it and use it, I hope this item can be active again! - Brand: ALPS MOUNTAINEERING - Color: Orange - Material: 100% Nylon - Style: Air Pad - Features: The mattress has a manual pump for inflating (see photo 3) 4-season - Size: Regular 20 x 72 x 3 inches (approx. 50.8 x 182.8 x 7.62 cm) - Stuff sack: Included Thank you for looking.
