This is the #3 model of Montbell's classic synthetic fiber sleeping bag, the Burrow Bag. Purchased several years ago. Used for 2-3 seasons of mountain climbing. Please be aware that there is some wear and tear. #3 is highly versatile and I used it from summer mountains to winter mountaineering. It's synthetic fiber, so maintenance was very easy, but it's somewhat heavy, so I'm selling it because I haven't used it much since I bought a down sleeping bag. ○ Item mont-bell Montbell Burrow Bag R/ZIP Synthetic Fiber Sleeping Bag Three-Season Exceloft Burrow bag 1121273 ○ Size Height up to 183cm Storage size Diameter 18cm Length 36cm ○ Condition I think there are no noticeable scratches or stains. ○ Color Blue * Purchased from Montbell directly managed store *This is a used item.
