What Our Gearhead® Experts Are Saying:“These are my go-to mitts for the stormiest days at altitude. The 3L GORE-TEX shell and Aerogel insulation combo keeps my hands dry and warm no matter what’s blowing in, and I love the under-cuff design for streamlined layering with my jacket sleeves.”We count on the Hemispheres Team GORE-TEX 3L Mitts to keep our hands warm, dry, and ready to grip the poles through deep days and alpine descents. Designed with pro-level performance in mind, these mitts blend elite-level GORE-TEX 3L waterproof protection with a modular system built to handle the most brutal winter weather. The interior is lined with a removable mitt made from ripstop nylon and filled with ultra-warm PrimaLoft® Gold Aerogel insulation, which traps heat without bulk—even in the wettest conditions. A full seam-taped construction and DVHardcore technology maximize waterproofing, while the under-cuff closure with a secure Velcro strap ensures a low-profile fit that integrates seamlessly with your shell.
