800 Fill Power

The top end of the market, offering exceptional warmth to weight ratios. 800 fill power is rare and expensive but gives expedition level performance or options for ultralight construction. The high loft down compresses well, keeping pack size down whilst standing up to the most extreme conditions

Rip Stop -

This is a lightweight nylon fabric with interwoven ripstop reinforcement threads in a crosshatch pattern. It is woven with a coarse, strong warp and filling yarns at intervals so that tears will not spread. Ripstop is used in construction of hot air balloons and yacht sails but in this case very effectively on outdoor clothing.

DWR

- Durable Water Repellent, is a coating added to fabrics to help add to their water repellency and shed water and snow more effectively.

Angled Foot Box

- Sleeping bags with an angled foot box have been made to fit your feet so that you can lie in a natural position making it more comfortable and also to reduce compression of the down and reduce heat loss.

Combination Down Construction

- High Altitude and Expedition down gear tend to use a combination of box walled and stitch through construction to reduce heat loss and spread the down evenly across the product while keeping the down in place. Combining the two construction techniques and the finest down create the warmest and and most effective heat retaining products.
