Description
This system is very similar to the one already used successfully on Broad Peak (see Case Study), but it advises a much warmer sleeping bag. The Hispar 600 only weighs a little over 200g (7.1oz) more than the bag used on Broad Peak, but it gives a greatly increased margin for mishap or bad weather, a necessary precaution on Denali.
As climbing kit, the Xero clothing is rated for -40°C (-40°F), and the night-time boost it gives the Hispar bag takes the system rating up to -47°C, the same as System 1 with the Xero Suit. The main difference is that the clothing in this system is in separate pieces. While the one-piece suit is simpler and often favoured for the highest peaks, separate clothing makes for a little more versatility and wider usefulness for the kit on trips to lower mountains.
Reviews
This review relates to Hispar 600 Down Sleeping Bag
"This bag has an unmatched warmth/weight ratio ... The draft tubes undoubtedly provide the best insulation behind the zip of all the bags tested – not a trivial detail if you face harsh conditions."
— from Carnets d'Aventures Magazine's test of 18 sleeping bags for cold conditions.
This review relates to Xero Down Jacket
"Peter Hutchinson makes probably the best down gear in the world and his Xero jacket has kept me happy (well as much as you can expect to be) deep into the minus 40 degrees."
— Nick Lewis, Climb Magazine.
This review relates to Xero Down Trousers
"Your down trousers were lovely to wear in the hard wind outside the tent during our ski tour last week in the Swedish mountains."
— Stefan & Susanne Grimfors.
This review relates to Xero Down Socks
"The Xero booties were great for sleeping in and I could also wear them inside my Sportivas for mooching around camp. All in all, perfect."
— Nick Lewis, Adventure Network International.
