Sized specifically to fit into Hestra’s Heli Ski mittens for women, this is a replacement or spare liner made from the same Bemberg/poly fabric and G-loft polyester insulation as the original. The Velcro wrist attachment system will mesh with your mittens for the same secure fit. Are your Heli Mittens starting to pack out and feel thin? A new liner will have them feeling like fuzzy new again. Are you planning a multi-day trip and want to be confident your hands will be dry and comfortable across the whole adventure? Adding a spare liner is cheap insurance against the damp and cold. These liners are machine washable, they are intended to be pulled out and refreshed now and then, and while they are machine washable, can easily be rinsed out while you’re traveling and left to dry while you use your spare pair. One of the things that makes Hestra such a fabulous brand is the ability to replace liners as they pack out and wear, there’s nothing wrong with your shell, it’s a shame to consider having to replace a glove when all you really need is a new liner. We’re often asked “how long does a liner last” and, obviously, this depends on how often you’re using your mittens and how rough you are on them, but most of us start the year with a fresh liner, and use the other one as a spare.
