This classic workwear attire just got tougher and warmer too. The Best Made Chitina Guide Sweater is constructed from 5 gauge heavy knit 100% Uruguayan Wool and boasts a couple of 5.5 oz waxed cotton elbow patches. It's been put through its paces in the plummeting temperatures of Alaska, so if, like us, you're not a big fan of hypothermia, get yourselves one of these.
