Klim Big Sky Fleece Lined Flannel Hoodie

The KLIM Big Sky Fleece Lined Flannel Hoodie is a heavyweight performance flannel hoodie built to provide serious warmth, insulation, and comfort in cool to cold conditions.

• Snap‑front closure: Classic button/snaps make it easy to put on and take off, and add to a rugged, workwear‑inspired look.

• Multiple pockets: Includes two side‑entry handwarmer pockets plus an interior YKK® zipper chest pocket for secure storage.

• Adjustable cuffs: Snap‑adjustable cuffs help seal out cold air and adapt to layering or gloves.

• Articulated sleeves: Designed for movement and flexibility whether you’re riding, layering, or working outdoors.
