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 0Hiro uses a combination of extra hardwearing and recycled materials, all treated with a PFC-free water repellent. 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.
'This jacket is superbly comfortable and just feels like a bit of a fortress on a wild day. For harsh and sometimes downright grim British winter mountain days, the 0Hiro is a reassuring prospect that's going to keep the foul stuff out and the warm in.' - Trek & Mountain (Editor's Choice, Belay Jackets Group Test)

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.
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.
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.
How It Is Made
PrimaLoft® Silver Hi-Loft Ultra is comprised of 70% post-consumer recycled fibres and the jacket lining is made from 100% recycled polyester.
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.
Where It Is Made
Our products are made in the best factories in the world. We know the factories personally and they have all signed up to our Code of Ethics in our supply chain. This includes the Ethical Trading Initiative base code, fair pay, safe working environments, no child labour, no modern slavery, no bribery or corruption, no materials from conflict zones and humane farming methods.
Reducing our carbon footprint
We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.
We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.

With your arms relaxed by your side, tilt your head down and ask a friend to measure from the bone at the base of your neck, over your shoulder and down your arm to the fold at your wrist.
Close fitting designed to conform to your body.
Slim and slightly contoured but not form fitting.
A comfortable fit that's not too tight, nor too loose.
A looser fit with a bit more space but not too baggy.
