The double suit is a quick-change suit for reacting to variations in temperature, and we’ve been hearing tales of its appearances on the world’s highest mountains.
A new documentary has been released about the explorer, author, and user of PHD expedition gear, Sir Ranulph Fiennes.
I've just returned from Vinson in Antarctica where your Xero down socks made life a breeze.
Lord Forsyth, former Secretary of State for Scotland.
These sizes are approximate, to the nearest half size, because down socks are roomy and soft by nature and exact sizings are meaningless.
N.B. Our standard sizes are S / M / L and XL. Other sizes available as a special order at additional cost. Please contact us for details.
* Please note: we make our stuff sacs big enough to allow fairly easy stuffing rather than reducing clothing to the tightest minimum.
Designed for fast moving expeditions to the highest levels or for any extreme cold weather venture where weight is at a premium, the Xeros pack up to almost nothing. Using Ultrashell fabric and a highly efficient lightweight construction these down socks can be a real boon on expeditions. And they'll double as mitts in a crisis.
Also available in length: long.
As used by Ben Saunders in the Serco TransArctic Expedition, Rosie Stancer, Rosie Swale Pope, in the Yukon Arctic Ultra, and by many others.
Included in Geographical Magazine's 'Ten of the best' list of essentials for keeping "the cold at bay".
One of the lightest of PHD's coated materials. This ripstop nylon provides complete wind block and good water resistance at minimal weight. Ultrashell gives an excellent upgrade to performance with very little weight penalty.
European goose down of very high quality. A truly excellent down with large clusters, consistent quality and lively long-term performance. More on our down insulation.
A technically advanced waterproof breathable material. 100% Nylon. Good abrasion and tear resistance, yet offering high flexibility for such a tough material.
"I've just returned from Vinson in Antarctica where your Xero down socks made life a breeze."
— Lord Forsyth, former Secretary of State for Scotland.
"The last night camped on the glacier at 4800m was one of the coldest I’ve experienced, -15 C inside the tent, and the Xero down sock (and Rondoy Jacket) were invaluable being worn inside my sleeping bag and helping me have a good night's rest"
— John Cameron, Rowaling Valley, Nepal
"[Your] Xero down socks are great."
— Ben Saunders.
"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, Antarctic Logistics.
