Choosing the Correct Version
This version combines Orion Blue with XXL sizing. Check the colour and size selected on the offer if either one matters, because both are part of the exact variant.
Before You Decide
Confirm the size, colour and slim fit before choosing an offer. Also check whether you want the insulated hood, adjustable hem and two zippered hand pockets that are part of this jacket. If you need a different fit or a different size, compare another version instead.
Weather Protection and Care
The stated DWR finish does not establish a waterproof rating. If you expect sustained rain, check the jacket’s stated weather protection and consider whether you will need a separate waterproof layer. Before washing, follow the garment’s care instructions for its down insulation and treated shell.
