This is an extremely durable bag. The conduit shell sheds water, and as long as you aren't sleeping in a swimming pool, it will keep yourself and the bag dry and warm. Bomber construction with heavy duty zippers and a rock solid collar system that keeps out any drafts. Packs down well in the included compression sack for a 3 season expedition bag with a weight of just under 3lbs.
Keep in mind, the regular bag is short with a max user height of 5'10. So if you're any taller, go for the long. Also just a heads up, unlike the picture online, this bag is blue.
