Advanced High Performance Apparel selected for being the best in its individual class. We look for the warmest, lightest, form-fitting, durable, compactable, and full-functioning products available. RangerMade operators understand the ever changing demands of the battlefield dictate the need for versatile layering systems that do not restrict mobility and can be rapidly modified to meet environmental conditions. As with all of our products we only endorse the absolute best in their class. There are too many features to list them all.

We applaud the Canucks on their determination to keep their jobs and technology on their own soil. Arc'Teryx designs the worlds finest Gore-Tex, and leads the pack with performance fleece as well.

It comes with a durable outdoor finish breaking new ground in the arena of performance fleece. Specs: 446g./15.7 oz Men's (Med.) Polartec Termal Pro Knit.
