Easily our best-selling sleeping bag
The Criterion Quantum 200 is an ultralight sleeping bag and the lightest down sleeping bag in our range. Designed for minimalists, ultralight hikers and adventure racers. With a comfort temperature rating of 0°C, this is a bag for the summer. Its weight is a mere 530 grams, so it will add hardly any weight to your rucksack. Made using a Pertex Quantum ripstop shell filled with 200g of 870 FP Polish Goose down. Boxwall construction helps keep the weight down to a minimum. A DWR+ treatment of the shell helps protect the down from any dampness that may occur in your tent, from condensation or wet gear. When in its stuff sack, the pack size of 11 x 11 x 25 cm is absolutely tiny. Since it takes up hardly any room you will be able to use a smaller rucksack on your adventure

The only single-layer constructions which do not create cold spots along seams are the "V", "trapezoid" and "boxwall" designs. The baffles in each of these designs do have sidewalls to keep the insulation in place. There are no "lines of cold" as a uniform thickness of insulation is present throughout the sleeping bag. The simplest is the boxwall design. The baffle sidewalls are vertical, hence the baffle shape is box-like. On the top side the trapezoid construction gives better performance than boxwall.
