Valandre has become one of the most famous names in mountaineering for a few very important reasons. Not only are their down products superior in design and fabrication, the strict methodology of choosing the actual down clearly separates Valandre from competitors. Valandre uses down from Bar Headed geese, whose migration patterns cross directly over the highest and coldest parts of the earth. These severe weather conditions demand the most thermally efficient down, which Valandre uses to keep mountaineers, hunters and recreationalists safe and warm all over the world. The Shocking Blue is one of the most technical of the Valandre sleeping bags. Originally designed for high altitude mountaineering the technical design keeps you warm without the weight of comparable bags. Strategically sewn with 91 separate pieces the Shocking Blue leaves no detail lacking. From the extra roomy, self supported toe box to the thermally efficient neck baffle the Shocking Blue was built for performance in any conditions. If you have a colder weather hunt planned the Shocking Blue should be on your radar!
