It took us 2 years of development to create one of the best lightweight, insulated jackets in the world, packed with industry-leading specs and features – but why do most brands save the high-end specs for their down filled jackets? Why not make the exact same jacket with a world-class premium synthetic insulation as well?  Introducing the NESSH FL700 Synthetic, a performance insulted jacket, with no down. Featuring ‘Featherless FL700’ fill from 3M, a synthetic insulation that gives industry leading warmth to weight and incredible compressibility. It’s the closest thing in the world to down, in both warmth to weight, feel, performance and compressibility.

The NESSH FL700 jacket weighs just 12oz / 350g and just like our original NESSH jacket, it features our proprietary, ultra-wind-resistant 10D ripstop nylon shell fabric and is longer in the back than front. The hood is helmet compatible making it ideal for pulling out of your pack while belaying and has an adjustable hem and hood to keep out cold drafts. The 2-way zipper from industry leader YKK can be unzipped from the bottom (or top), making it ideal for wearing over a harness or bulky items.

Wrist gaiters – seriously why does nobody else put these on insulated jackets? – keep your hands warm and can be tucked away when not in use and prevent unwanted sleeve drafts. Other features include x2 insulated waist pockets (with zippers), two deep inside pockets (ideal for a map or pair of gloves) and a zippered chest pocket for phone and valuables. The NESSH jacket even packs into its own pocket for easy storage.

Seriously – this is the exact same jacket, with the same awesome specs, same performance materials, same amazing colour range, but with NO down whatsoever. Simple.

Available in 4 colours and in a range of sizes.
