0Hiro [Mens]synthetic jacket

0Hiro is a warming insulated synthetic jacket making it a great choice for slinging on in early starts as you crawl out of the tent, late finishes coming down off the hill, after a swim in the ocean, waiting for a midnight change over during a 24hr mountain bike race, or sitting it out on a high ridge.

Ideal for cold wintery conditions. Can be used as a belay jacket on chilli stops, and as a very warm outer layer.

An ideal warming layer when crawling out of the tent on a fresh early start. Throw 0Hiro on while you are sat waiting for your partner to follow you up a pitch or batten down the hatches whilst you sit out a storm and wait for the sun to rise.

0Hiro (pronounced zero-hero) is particularly durable making it a great choice for slinging on after a swim in the ocean, waiting for a midnight change over during a 24hr mountain bike race, or sitting it out on a belay ledge. The large adjustable hood is non-detachable allowing it to trap heat better, it also fits over a climbing helmet making it ideal for climbing. There are wrist warmers with thumb loops integrated into the sleeve of 0Hiro; this further traps heat in without restricting dexterity and the versatility to wear gloves over the top. 

The enormous pockets are suited for thicker gloves, phones and cameras or stashes of energy food.  0Hiro can be thrown on top of wet clothing and will warm you up- you might still be uncomfortably wet but at least you will be a bit warmer!

  • Integrated wrist-warmers
  • 2 large outside zipped pockets

Why synthetic? There are many advantages to down clothing, but when down jackets are exposed to the elements- something which can be difficult to avoid in our temperamental climes- they have a tendency to lose their benefits.Synthetic jackets far excel in their ability to perform when wet. 0Hiro can retain heat when wet and will dry much faster than its down equivalent. 0Hiro (medium) fits in a XS Vortex bag.

Nice and warm but doesn't breathe

Bought this when it first came out, great and warm when you are standing around but like being in a bin liner if you exert yourself as it doesn't appear to breathe at all.

I need 0hiro

Bonnie Tyler could hold out til the morning light with ease in this jacket. Well constructed, great fit. I'm 5'8 slim build and the small is a snug (but not tight fit) - similar to that of my Montane Flux jacket. Only gave it a four as I haven't it belaying yet.
