Nano Primaloft
A Primaloft jacket with a seam sealed waterproof shell, the Nano is suitable for the most testing conditions. Heavily influenced by the garment that the NZ and Australian Antarctic programmes have been using for years. The combination of a lightweight waterproof and breathable Entrant shell and 135gm/m2 Primaloft Gold means warmth you can depend on, and our usual attention to detail, cut, and performance mean function and breathability to the usual Earth Sea Sky standards. Throw this on when you're at the belay, or taking your skins off before the next run, knowing you'll enjoy it more and perform better with this keeping you warm.

Been wearing this jacket for skiing and alpine climbing (as my warmest jacket). ESS nailed the combination of lightweight and warm. Was also very impressed by its waterproofing. Cant recommend the nano primaloft enough! Review by Hamish / (Posted on 9/12/2018)
Top Notch!
I'm a landscape photographer who recently (May 2017) spent four weeks traveling around the South Island of New Zealand. It was deep into Autumn and this jacket kept me very warm while hiking up hills/mountains in the dark, wind and rain.
I wore it only on the coldest days and just a base layer underneath was perfect for me.
I'm really glad I bought this jacket and would highly recommend to anyone venturing into the cold this winter. Review by Nick Crarer / (Posted on 22/06/2017)
An excellent alternative to those ubiquitous puffer jackets. 'Super light weight' is right (lighter than my previous, decades-old Primaloft jacket) and the combination of featherweight-ness and fabric textures (tough outside, silky inside) make it very comfortable. It and a T-shirt are sufficient at 0c. And since it is not quilted, it is fashionable without being out-doorsy for city wear. I'm tempted to get a second. Review by Frank / (Posted on 22/03/2017)
Simply Excellent
Im currently in Antarctica working the Summer and this is my daily 'go to' garment. It is simply awesome! Super light weight and superbly fitting, it has kept me warm in -20c windchill factor with only a woolen baselayer underneath. Coupled with an ESS fleece layer and I'm absolutely toasty all day, and its a long day.. Review by Wayde Maurer - Helicopter Resources Engineer / (Posted on 23/11/2016)
