Our tapered rectangular bag is offered in 3 sizes averaging 1350gm of 600 loft duck down, creating an economical sleeping solution. Combined with the Polar Over Shell it creates a cosy haven for the most extreme conditions.

Various combinations of down quality, shape and fabrics are available on request

The over shell is designed to have our down bag zipped inside. The twin zip enables two bags to work as one. Filled with 320gm/m2 of 3 denier & ultra fine 0.9 denier synthetic insulation. These bags have excellent loft recovery after long term storage, and being synthetic they provide an excellent backup in melt or wet conditions.

The Sleeping bag expansion insert is a handy way of minimizing the gear pool. Some polar customers purchase only regular sleeping bags and for the larger expeditioners they use an expansion insert for extra space (width).
