Criterion says:

The Criterion Ultralight 350 is an extremely lightweight sleeping bag, designed for minimalists, ultralight hikers and adventure racers. With a comfort temperature rating of -3°C, this is a bag for the summer. Its weight is a mere 765gms, so it will add hardly any weight to your rucksack. It is made using a Pertex Quantum (52gms/m²) ripstop shell (formerly Pertex Microlight) filled with 350g of 700 FP Polish Goose down. Trapezoid construction eliminates cold spots enabling a comfortable night's sleep.

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 12 x 12 x 27 cm which is absolutely tiny. Since it takes up hardly any room you will be able to use a smaller rucksack.
