Purchased these for a climb of Mont Blanc. Unfortunately the sizing chart is waaay off (chart said I was a M, I bought L, still too small), so I ended with gloves that were a bit too tight, but they kept my hands exceptionally warm and dry and handled rock scrambling and rope management very well. I actually used the shells with three different liner gloves, the ones that come with the Guide Gloves being the thickest and warmest (by far). In warmer temps the Guide shell worked very well with the lighter liner gloves.I will be curious to see if the tightness creates a circulation issue in extremely cold temps, but in moderately cold (25 F) and extremely windy (60 mph) weather, it was fine.
"Warmest and most durable glove I've ever owned"
Been wearing these for three winters now, and the shells are still pristine. The inners are getting pretty thin, but I've worn them for everything from snowmobiling to mountaineering. Wore this glove most of the time on Denali, including summit day. Only time I needed mittens was during extended traffic jams. It's got all the dexterity needed for working with gear and tying knots. Only gripe is that if you're hands get too hot in them, and they absorb some sweat, once you take them off the insulation can make it pretty hard to get back on straight. But I've experienced that with most well insulated gloves so...?
Like putting your hand into a soft fluffy oven. I have terrible circulation for a dude my age and my hands get cold when its 75 degrees out. I have been through countless pairs of gloves and these are the best I have found. Only wish they had a drawstring or a velco wrist strap of some sort. Oh well. Nothing can be perfect.
