Like putting your hands in an oven... but less painful.
Black Diamond's most versatile and popular year-round mitt, the Mercury Mitt features a combination of innovative Empel DWR on the shell, a BD.dry waterproof insert, and a removable PrimaLoft insulated liner for maximum warmth and dexterity.
The removable insulated liner, filled with Primaloft Gold Cross Core, dries quickly, and insulates even when wet. A four-way stretch fabric shell and a long gauntlet cuff keep spindrift and moisture outside, while the goat leather palm and additional reinforcement layer stands up to rocky terrain, repeated rope handling and the general wear and tear associated with dedicated mountain use.

Guide Pick
RMI Expeditions Guide
,How Guide Pick™ Works

The guides over at RMI collectively spend over 10,000+ days a year on the world's highest mountains, climbing hundreds of thousands of vertical feet. They put their gear and apparel through the wringer. This stuff is their work wear and they simply will not tolerate inferior gear.

At the end of the climbing season, guides are given a survey to find out what gear they are using and why it is their favorite. We don’t often get complete agreement but we do get alignment and by looking at the data, a few clear winners rise to the top in each category.

We take those winners, and stamp them with the Guide Pick™ logo on our site. We also compile this wonderful little document, which you can use to see top contenders, gear advice, Guide Quotes, and more.
