Aggressor Armored Shirt 2.0

Klim Aggressor Armored Shirt (w/o Back Pad) – Armored Base Layer for Mountain Sledding

The Aggressor Armored Shirt w/o Back Pad combines a warm technical base layer and torso armor in one breathable, low-bulk layer. The midweight Aggressor™ 2.0 grid fleece traps heat and wicks sweat, while EVA impact padding and a TPU chest plate protect the chest, ribs, shoulders and upper arms. The armor compound stays flexible in cold temperatures—built for mountain/backcountry snowmobiling.

Note: This version is designed to be worn with a backpack (no back protector included). If you don’t wear a backpack, choose Aggressor Armored Shirt w/ Back Armor. If your jacket has shoulder pads, remove them to avoid stacking.
