Cons Difficult setup, zipper/entrance frustratingStuff sack too largeOverkill for milder climates, heavierLeaky zippersExpensive, no zipper
Bottom Line A functional piece of equipment the line between a single person ultralight tent and a bivyWe searched high and low looking for some drawback with the OR Helium Bivy and found noneThe Alpine is ultra capable in cold and wet environments; a true four-season bivyA functional, lightweight bivy with several features to keep you comfortable and a few bucks in your walletA lightweight and simple model that helps protect against unforeseen wind, weather, and cold
