I have used the Mitts on several trips now in temperatures ranging from -10F to about 35F, with and without Possum Down liners and despite multiple attempts from my girlfriend to steal them from me (her hands are always cold). In addition to ve extremely lightweight the design is great, especially the gauntlet hem elastic drawcord and the grosgrain ribbon wrist closure to reduce/eliminate drafts. The surface is grippy indeed but mitts have their inherent limitations when gripping hiking poles.
These mitts will keep you toasty!! I would personally NOT wear them when hiking in temps above 15-20F (I wear the possum down liners instead). They are great for very cold conditions, to warm up your hands during breaks and at camp.
Overall, they deliver what they promised to. Expensive yes - but the best cold weather mitts out there.
