Arc'teryx Alpha SV Bib
For our Fall/Winter 2013 collection, we have brought forward several updates to the classic Alpha SV Bib, refined for serious alpinists, in both women's and men's styles. Intended for the most severe conditions and undertakings, the new GORE-TEX® Pro textile selections for the Alpha Bib have strong nylon fibres in the face fabrics, targeting areas of most exposure with N155p-X GORE-TEX® Pro, while the main body of the bib uses the Arc'teryx-exclusive N80p-X GORE-TEX® Pro. GORE-TEX® Pro is the hardest-wearing waterproof/breathable membrane, engineered to match the interval rate of guides, climbers and outdoor professionals.
Featuring a full crotch zip that works with harnesses, the Alpha SV Bib incorporates e3D patterning to accommodate movement of maximum winter layers without constriction in the articulated seat and knees. Full length side zips open wide when dressing over boots or crampons, and can be adjusted for ventilation.
Climbing-specific design features on the bib include reinforced knees, Keprotec® insteps, two large bellowed chest pockets that sit high on the bib, hem grommets and boot hooks. A newly developed LegWrap™ system reduces pant leg volume with a simple internal strap to reduce the risk of crampon snag. To increase breathability and protect the lower back and kidneys, the bib uses a full stretch FortiusTM 1.0 softshell textile.
