mont-bell Stream Parka Men's M Hard Shell Jacket Item No. #1102517 - While the current model uses Super Dry-Tec®, this one is made with GORE-TEX Fabric 3-layer. - Regarding the stuff sack, I used a larger one, so the mont-bell stuff sack is unused. Also, I don't think the jacket has any wrinkles, but please understand that it is not new. - Please refer to the photos for the condition of the item. I put it in a backpack a few times and went on low-altitude hikes (around 1000m), but I only used it 1-2 times (for cold mornings, no rain or snow). After that, it was stored at home. I have 2-3 mont-bell stuff sacks at home, all unused, but I don't remember if the one in the photo is for the Stream Parka, so I will include the largest bag. This high-strength model is suitable for winter mountain trekking and ice climbing over 3,000m. It uses a shell material that combines the strength to withstand harsh use and a supple feel thanks to GORE® C-knit™ Backer Technology. The unique "K-Mono Cut™," which minimizes the number of seams, provides excellent waterproofness, durability, and ease of movement. It is equipped with many features to make winter mountaineering comfortable and supports activities in harsh environments.
