An all-around slim fit with no hand pockets and a four-inch technical collar and hood make this the ideal hoodie for under your harness and helmet. It’s a great option for layering under your other workwear, too. Thermoregulating fabric with four-way stretch keeps you comfortable and mobile in all conditions. The slim cut doesn't compromise on details to enhance performance, like an underarm gusset for freedom of movement and elasticized sleeve cuffs that help keep out debris.
