The Forty Below Mug Boot is an insulated cover designed to fit the GSI Fairshare Mug, helping keep your drinks and meals hotter for longer.


This handy cover is made from 1/8” (3mm) thick closed-cell neoprene foam and wraps fully around and beneath the mug. The bottom features a rubber-coated exterior to help prevent slipping. Designed to fit the Fairshare mug snugly, the Mug Boot includes a small notch at the top rim that fits into the handle, helping to secure it in place. For extra hold, you can optionally add a small piece of double-sided tape along the rim.
