What Our Gearhead(R) Experts Are Saying:"I wore the Cassiar Pro ODX Shell on an exposed ridge traverse when a storm rolled in out of nowhere, and it held up through hours of sideways rain without a single cold trickle finding its way in. The two way zipper let me vent on the climbs without losing that seal, which made all the difference on the steeper pitches. This is the shell I grab now anytime the forecast looks unpredictable."Weather turns fast above treeline, and the Cassiar Pro ODX Shell from Columbia's Titanium line is built for exactly that uncertainty, the ridge walk that starts under blue sky and ends in a sideways downpour with miles still to go. OutDry Extreme seals the membrane straight to the face fabric, so rain stays out while the wicking interior keeps things from turning clammy. External seam tape backs every stitch, the two-way zipper vents heat without letting water in, and the adjustable hood holds its shape without blocking peripheral vision. A drawcord hem and droptail back seal in coverage right where a pack rides.
