I used the bag at the North pole and on Aconcagua. It was fantastic and the source of much jealousy especially when it dipped to minus 35C"

The Diamir down sleeping bags raise the sophisticated Baltoro shell design to a new level by the use of PHD's exceptional 800 down and inner Drishell panels at head and foot. The Diamir represents the new bench mark for sleeping bag standards.

900 down option

This option extends the range of this bag down to -58 C. Weight stays the same. Read more on our exceptional 900 down.

As used by the BBC's Tribe team in Siberia, by racers in the Yukon Arctic Ultra, and by many others.

†Please note: we make our stuff sacs big enough to allow fairly easy stuffing rather than reducing the bag to the tightest minimum. What air is left in the packed item will easily be compressed out of it, if you are squashing it into a small space in your rucksack. Tiny stuff sacs look impressive: but unless you are a sac-wrestling fan, fighting the gear into them day after day can be an unnecessary chore.

‡Please note: the optional HS2 outer is a complete extra outer shell, with seams taped for weatherproofness. The extra layer of fabric adds considerably to the weight and bulk of the basic bag (around 180gm - 6oz). It increases the weatherproof qualities of the bag in mountain or arctic situations, but it is not a substitute for a proper bivvy bag when sleeping out in the rain.

"I am just writing to say how impressed I was with your Diamir 1200 sleeping bag. I used it for a week while taking part in the Yukon Arctic Ultra. I was really impressed and would thoroughly recommend it. Temps got down to -35c . . . knowing how good the bag was, was really reassuring". S.E.

"My Diamir 1200 was plenty warm enough on Mt. Vinson where the temp hit -30 Celsius in camps where we lost sight of the sun for several hours. In fact, in the sunnier camps the bag was so warm that I'd routinely strip off down to my bottom layer of thermals". Nick Lewis, Antarctic Logistics and Expeditions
