Jack RABit Fastpacking Jacket System
The Jack RABit is a 2-in-one jacket system. The base layer is zoned with Polartec alpha direct 4004 in areas of high output, including where the backpack straps sit on the body. The front is layered with climashield apex 2.5 for ultralight insulation, even when wet with precipitation or sweat.
The back of the base layer has a pocket that deploys a shell that snaps around the backpack, making for easy donning and doffing without needing to stop forward movement.
