Designed to provide exactly what is required on rapid high altitude ascents or lightweight arctic travel for expeditions. Suitable for those who are opting for the versatility of separate down garments over one piece suits. Insulation level is similar to the Xero Down Suit with the Standard fill.

"The Xero jacket was perfect for summit day where we had a combination of -25C and 20 knot winds. It is the best down jacket I've ever used".
Nick Lewis, Adventure Network International

† Please note: we make our stuff sacs big enough to allow fairly easy stuffing rather than reducing the jacket 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 rucsace. Tiny stuff sacs look impressive: but unless you are a sac-wrestling fan, fighting the gear into them day after day can be an unncecessary chore.

"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.

"Just a quick note to thank you for the timely supply of the PHD down gear before my Mt Vinson trip. The gear was absolutely first class. I used the Xero 900 down jacket on our summit day which was -26C with a 30-40 knot wind and they were faultless" Mark Dixon.

"I've just returned from Vinson in Antarctica where your Xero down jacket made life a breeze." Lord Forsyth, former Secretary of State for Scotland.

"Just a quick note to let you know that ALL 5 members of our team reached the Summit of Cho Oyo (8201m). Another member of the team wore [your] Xero Down Jacket and...was comfortable and impressed. Thanks for the great gear". 'Lanx', Equipment buyer, UK Reserve Forces Seven Summits team.

"The Xero jacket was perfect for summit day where we had a combination of -25C and 20 knot winds and the thigh-length design meant that I never needed to wear the Xero trousers. It is the best down jacket I've ever used". Nick Lewis, Adventure Network International

"Very happy to report that the Xero Jacket performed fantastically and kept us warm and safe especially during summit day where temperatures dropped below -30 deg C." Robert Gatt, Challenge8000, on Cho Oyu.

"Just a short note to thank you for making my Xero down jacket in super quick time. I am over the moon with it. What a pleasure to buy from committed experts. Never again the usual naff US brands where everyone knows they are made to far eastern specifications, in other words a cheaply as possible. I am still grinning". P.S.

"Many thanks for the Xero Jacket for Cho Oyu which worked very well. " J.P.
