The whole jacket is constructed from Arcteryx's own N100p-X nylon fabric, an upgrade from last year, improving the durability and overall making the jacket a lot more burly and abrasion resistant. The textile is tightly woven to give a flat, smooth face fabric that sheds water amazingly well, reducing the amount of re-proofing required. Combine this amazing fabric with Gore-Tex Pro and you get probably the best mountaineering jacket available today. Fully featured and virtually indestructible, the Alpha SV is a long term investment for serious end users who demand the best.
Sleek and stylish by design yet fully technical, it has been stripped to the bare essentials to reduce weight without compromising performance. Traditional bellows chest pockets sit high enough to avoid a climbing harness or pack belt, the hugely adjustable storm hood fits over any climbing helmet, yet can be cinched down with single handed cord adjusters. Adjusting the hood is simple and easy enough to adjust, even with the use of thick gloves or mittens. The ingenious HemLock inserts stop the jacket riding up when wearing a harness.
For 2016, Arcteryx have changed a few aspects of the jacket, one being the seams. Strategically placed 8mm tiny seam tape massively improves breathability for a start as moisture can't easily pass through tape, the less tape used without compromising durability, the more breathable the jacket becomes. On top of being more breathable, it also decreases pack size and weight.
WaterTight pit zips have been added to further increase breathability and ventilation, meaning in faster moving activities there are more options to keep cool.
