The Vertex is another one of our pieces that has been rigorously tested in Colorado's frigid winter temps and bears our proprietary WX-D, weather defense seal. Over the two years it took to perfect every detail, we continuously rode the Vertex in cold and wet conditions and temperatures ranging from 0° – 40°. The Vertex is probably one of the lightest cold-weather jackets you'll own (just 383 grams in a size medium), but the efficiency of the wind-stopping fabric face and thermal, grid-fleece lining against your skin guarantees you will stay warm in extreme cold.
The fabric combination is so good at blocking chill and retaining interior warmth that we added two zippered front vents to allow for temperature regulation during exertion. Gusseted cuffs have been designed to pair nicely with gloves, a waterproof zipper protects against road spray, critical seams are taped internally for more robust waterproofing, and all-over reflective external seam taping ensures extra visibility in low-light conditions.
