This is achieved through use of high quality down fill (800 loft white down ), ultralight shell (10 by 10 denier, 520 thread count Nylon weighing only 26g/m2), & tapered rectangle design. Versatility is maintained through use of dual zippers & tapered rectangle rather than full mummy shape. DWR Loft treatment adds greater resilience, higher loft and better warmth in damp conditions.
