The Crux Torpedo 900 is ideally suited to climbing Himalayan peaks in the 6,000m to upper 7,000m category.
Only down is able to give the warmth for weight and pack size required for such demanding situations. The Crux Torpedo 900 uses the best down available, 850 fill power Polish goose down (it's ethically sourced too) and has a comfort rating of -8C and lower limit of -18C (EN13537).
Whilst the waterproof 2 layer eVent outer isn't the lightest, most compact fabric going, the fact that it is durably waterproof means that both you and the down won't get wet on snowy and damp bivvies, and that you won't need the extra weight and bulk of a bivvy bag for snow holing and cold weather camping. The breathability of the shell helps internal moisture management meaning that your down won't freeze and get bulky and heavy. Each slant wall baffle not only reduces cold spots they are made from mesh and are therefore very light. Each baffle is laminated directly to the eVent outer, unlike other waterproof sleeping bags where a waterproof outer is stitched over an existing bag, and thus the Torpedo range save loads of extra weight. The zip is a highly water resistant Riri Aquazip which uses diving suit technology to keep the zip as robust and watertight, yet light and as easy to use as possible.
The medium sized bag has 900g of down, an overall weight of 1500g and 188cm internal length.
All in all, this is a fantastic bag for mountaineers operating up to 7,500m during the summer or for fast and light 8,000m peak dashes. It is equally suited to winter ascents in the Andes, Caucasus and lower Himalayan peaks.
The Crux Torpedo 900 is a waterproof sleeping bag designed for summer mountaineering up to 7500m, and 4 season to 6500m.
