Description

The 0Hiro provides a robust and resilient shelter from the cold regardless of the forecast.

  • Primaloft® fill insulates when wet and keeps loft for longer
  • Highly abrasion resistant Nylon 6,6 outer fabric
  • 5K/5K waterproof membrane for damp weather performance

In your hour of need, shivering your bits off in the deep damp of winter with no layers left, you need a hero... you need... a 0Hiro. The 0Hiro uses Primaloft® Silver Hi-Loft Ultra, a synthethic insulation that lofts even when wet, retaining over 85% of its insulating ability. It also survives repeated compressions better than other Primaloft® fill, keeping your jacket working for longer.

The outer is made from a bombproof nylon 6,6 fabric, allowing it to withstand a thorough trashing and season after season abuse. It also means you don’t have to worry about leaving a breadcrumb trail of insulation on the mountain behind you.

We’ve added a 5K/5K waterproof membrane to the back of this fabric to give you an extra layer of defence in deep powder, wet sleet and persistent drizzle. The 0Hiro isn’t seam-taped for sustained rainfall, but it’s certainly enough to get you off the hill before the damp seeps in. It’s even been whispered that it'd double up as a mighty fine ski jacket.

For mountaineering use we’ve included a helmet-compatible hood with a wired peak to deflect scattering spindrift and inner cuffs stop snow and draughts from creeping under gloves. The main zip is two-way for belaying ease and the sleeves have slightly less insulation than the body to allow to you swing your axes freely.

The 0Hiro is designed to fit over multiple layers but you may need to size up if you’re planning to use it as an out-and-out belay jacket.

Sustainability and Product Care

Product Care Information

When your 0Hiro stops beading, wash it in pure soap or a tech wash (like Nikwax Tech Wash or Grangers Performance Wash) to keep the water repellent treatment working at its best. You may need to reproof your jacket once or twice a year, depending on usage.

Repairs
We have dedicated Repair Stations in our stores and we're fully equipped to breathe new life into your old kit. This includes spare parts, patches, new zips and wash and reproofing of your down and waterproofs. Pop into any store or contact us online for more info.

Alpine Bond
If one of our products does not meet your expectations upon delivery, or if during its lifetime does not live up to the demands placed upon it, please return it to us for repair, replacement or refund. If the problem is our fault then we will do this to your satisfaction. If it’s your fault then we will help out the best we can. Find out more about our Alpine Bond here.

Sustainability

Recycled Materials
Primaloft® Silver Hi-Loft Ultra is comprised of 70% post-consumer recycled fibres and the jacket lining is made from 100% recycled polyester.

PFC-Free DWR
The 0Hiro uses a completely PFC-free DWR treatment on its outer fabric. PFCs are potentially harmful and have been found to build up in the environment. We don't like the sound of that so we've been working hard to get rid of them.
