M.E.’s Arclight Jacket is their most breathable, fully weatherproof jacket out there. Made from super breathable Polartec Noe Shell fabric, this jacket is ideal for the fast moving, highly active mountain goer. Polartec Neo Shell has a hydrostatic head of 10, 000mm so it does a great job at keeping water at bay; this fabric comes into its own in the cold & rapidly changing conditions that you find on long, multi-day ski tours. The Mountain Hood is fully adjustable with a smaller cranium volume than the Mountain HC Hood. Unfortunately this mean that you can’t fit a helmet underneath, however this hood provides a more secure & precise fit, which is what this jacket is all about. Sticking with the secure & precise fit theme, Mountain Equipment has constructed this jacket around their Alpine Fit Block. This is a close fitting cut yet it still allows room for low volume layers & has been built with manoeuvrability in mind. M.E. have used a new shoulder construction & new seam placements to reduce tightness & “bagging” in one foul swoop. The guys at M.E. have used all of their Storm Construction techniques during the design & build of the jacket. Everything form seam construction, placements & taping; which face fabrics to use, bar tack reinforcement & storm guarded YKK Aquaguard zips. Fort Knox Federal Gold Reserve has nothing on this jacket when it comes to keeping things out.
