The Men’s Alpha FL Jacket from Arc’Teryx is a fast and light jacket for high aerobic, non stop climbing routes on long days. It features 3 Layer GoreTex Pro fabric and water resistant zips to help keep you dry and comfortable throughout the day. The trim e3D fit of the jacket means it is cut to fit closer to your body allowing full freedom of movement without unnecessary rising at the waist, it also enhances breathability and won’t cause excessive drag while out on a windy day. The StormHood is helmet compatible and adjustable so that it will fit just as well on days when you don’t need a helmet. The Hemlock technology employs two removable pieces of foam located at the hem of the jacket which help lock the jacket in place underneath a harness to stop it riding above the waist and getting in the way when climbing.The simple features on this jacket make it ideal to keep climbers, ice climbers and alpinists alike, comfortable, dry and confident that they can trust in their gear.
