38-year-old stroke survivor Jonny Huntington has begun his world-first Antarctic expedition to become the first disabled person to ski solo and unsupported to the South Pole.
Sir Ranulph will be sharing stories from his legendary exploits and adventures live on stages across the British Isles.
Last week I climbed the North Face of the Eiger ... Both my self and my client used your Zeta sleeping bags. They were just fantastic and completely idiot proof. Mark Seaton.
The measurements in the tables below are personal body measurements.
†Please note: We make our stuff sacs big enough to allow fairly easy stuffing rather than reducing the bags to the tightest minimum.
‡Please note: The optional waterproof Dri-LX outer provides an extra seam-sealed outer shell to the bag. While a shelled sleeping bag is not designed to be used alone in heavy rain (the hood area is open to the elements) the shell does protect the bag when it is used outdoors without a tent.
Recently redesigned
Updated with Primaloft Gold filling and a greater range of build options, the redesigned Zeta 2 synthetic sleeping bag is now 35% lighter and more compressible than before. The new, taped water-proof Dri-LX shell and insulated overhead cowl options boost the bag’s performance in extreme conditions.
Combine with the Zeta Overbag to extend the use of this specialist bag from -20°C to -40°C.
Designed specifically for climbers' bivouacs in damp conditions, with all the advantages of Primaloft-Gold synthetic fill and water-resistant Ultrashell outer fabric. The twin front zips, an extra bivvy feature, double as arm holes for cooking and gear sorting. The large inside chest pocket keeps stashed kit warm. An optional insulated cowl cover (in Dri-LX fabric) sheds snow. The reflective strip and clip loop confirm this bag is one for climbers in extreme situations.

Read our technical briefing on down vs synthetic insulation.
At just 64gsm, Dri-LX is our lightest 2-layer breathable waterproof rip-stop nylon fabric. Its remarkably low weight not only makes for a lighter load, but also reduces pack size. Its excellent waterproofing qualities are in part due to how it can be taped at the seams to create a waterproof shell for sleeping bags and clothing.
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.
A mini-ripstop nylon with excellent tear strength, MX is the pick of the superfine 15 denier downproof materials. We have tested lighter fabrics, but most have had significant drawbacks, while our confidence in MX is based on several years of extensive use in both our ultralight and our high mountain gear.
Primaloft Gold® is the ideal microfibre insulation. Ultrafine fibres produce an insulating core that is incredibly soft, lightweight and water resistant. In our experience it absorbs water much more slowly than other waddings, a marked advantage in wet-cold conditions.
The nearest of the synthetics to the feel of down, yet tougher than you would expect. Primaloft Gold® offers the best warmth/weight performance in the Primaloft range
"Last week I climbed the North Face of the Eiger ... only the 2nd time a British Guide has done this. We had two bivys on the face and one on the summit. Conditions were difficult and we wore crampons for the entire route. Both my self and my client used your Zeta 2 sleeping bags. They were just fantastic and completely idiot proof. " — Mark Seaton.
