More than just a liner!
I love this liner. Some folks look at this as extra weight but to me it its more than a liner. Yes its almost a quarter pound but still one of the lightest available. After having 2L of water from a hydration bladder emtpy in my pack and a poorly placed foot on a slippery river crossing you will quickly come to appreciate the benefits of using one. I use the 55L in my Aether 85. Its denier is the perfect balance of strength against abrasion and tears but still maintains a decent weight. It works great as a bear bag if needed. Here in the PNW we get alot of rain and being 6'1" and a restless sleeper I often end up with my feet brushing the tent wall and with a down bag that can cause cold nights and delays when your trying to dry out your bag in the morning so not to pack it damp leading to more issues down the road. It has a large opening that swallows the lower foot and half my Plasma 30 with my legs inside. This liner is a great piece of gear and a good value, I would get it again if it needed to be replaced!
