Loaded with 800-fill of responsibly sourced down, the Trevail is the ideal lightweight insulating layer when hiking. For its weight, down is the best insulator out there and it's exactly what you want to wrap up in when the temperature drops or you're at rest. The linear baffles insure the down doesn't migrate, maintaining uniform insulation throughout. Another benefit of down is its compressibility. You can stuff the Trevail Hooded Jacket into its own pocket and store it in your backpack. Pull it out, give it a shake to fluff up the down and it's ready to lock in body heat again. This jacket features a close-fitting hood, internal elasticated cuffs, an adjustable hem, two zipped hand pockets and a zipped internal chest pocket that's media compatible.
