A trim fit with a great warmth-to-weight ratio makes it a fine layering choice for the backcountry.

A great choice for backcountry pursuits the Arc'teryx Men's Delta AR Zip pullover offers a superb warmth-to-weight ratio. This is due to the fabric choice for this garment the Polartec® Thermal Pro® high loft grid that traps plenty of heat without the bulk. Also it has a trim fit so it layers well and thus there’s not a bunch of extra fabric to haul around when not in use.
