Oak Harbor is designed as a hoodie, but provides the same level of warmth as a jacket. The sleeves and side panels are made from a stretchy, soft polyester material with a fleece interior.

The jacket is quilted and padded on both the front and the back with Sustans® made from recycled material from DuPont™ Sorona®. The ladies' jacket features a hood, while the men's jacket has a collar. Lockable zips on the front and side pockets.
