The M1 PRO takes everything that makes the M1 a workhorse and turns up the heat. Full water-resistant goatskin construction blocks the wind, and double the Polyfil on the back of hand (80g vs. the M1's 40g) over a 250g Polar Fleece lining keeps warmth locked in when temps drop. You still get the dexterity to work buckles, zippers, and ropes — just with more insulation for the cold days. When dexterity is non-negotiable but you need more warmth than the M1, this is the one.
Best for: cold days when you still need to work with your hands.
