Sirius

The Sirus jacket, weighing less than a kilo, is your best choice for fast and light expeditions. The low weight and packability make this jacket the top choice for those who don't want to compromise on safety or features.

Cosmin Andron - Romania, summits Denali (18.567ft/6189m) after soloing the Cassin Ridge 2010. Denali or McKindley, is a interesting "pile of stone", as the elevation from base to summit is 18.000ft/5.500m, where Mt Everest is "only" 12.000ft/3.700m. To do it, you can add extreme cold conditions due to the northern situation in Alaska.

The Sirus's sleeve construction provides full mobility without binding or shifting down. The jacket includes a long list of features including fully reinforced sleeves, cuffs and shoulders; a velcro closure at the cuff; and elasticized draw cords on the high protective collar, waist and hem. A detachable semi tunnel hood easily snaps on and off. The hood is fully adjustable with velcro and draw cords to protect your face and head from heat loss.
