The ThirtyTwo Gateway Glove is an insulated winter glove filled with 100 grams of 3M Thinsulate Featherless insulation. A 2-layer shell rated 15K for both waterproofing and breathability surrounds it, and taped seams close off the stitching. What Our Gearhead(R) Experts Are Saying:"I wear these from the first lap to the last, and my hands finish the day dry from the inside. The shell breathes enough that sweat escapes instead of sitting against the lining, so the insulation keeps working in the afternoon."
