I have no personal experience with these sleeping bags, but I own four Kelty packs and they're absolutely amazing: top-notch workmanship with durable materials. Plus, Kelty's customer service is absolutely amazing: every report of customer service is glowing: whether the problem was manufacturing (rare) or user error, they go above and beyond to work with their customers. You can't go wrong with a Kelty product.
