Andrew Skurka on December 28, 2022 at 5:36 pm I constantly buy the Altitude liner, since it’s not Significantly costlier or heavier than another versions, mainly because it provides you with the option to go reduced compared to the Many others, and because there’s a simple Alternative if you don’t will need this type of heat liner (you take off the gloves and clip them into a carabiner with your shoulder strap).
