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.

Whether it’s burrowing through snow in Scottish winter, wrapping up warm after a wild swim or  stuffing in your pack for summits and lunch stops, the 0Hiro is the perfect jacket for the moist maritime winters we’re all too familiar with in the British Isles. 

The 0Hiro provides a robust and resilient shelter from the cold regardless of the forecast. Unlike down, Primaloft® Silver Hi-Loft Ultra maintains its loft when wet, retaining over 85% of its insulation value, and survives repeated compressions better than other Primaloft® fill, keeping your jacket in tip-top insulating condition for longer. 

Primaloft® Silver uses 70% recycled fibres and we’ve used 100% recycled polyester for the liner. The PFC-free DWR coated 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 TPU waterproof membrane to the back of the outer to give you an extra layer of defence in deep powder, wet sleet and persistent drizzle. The jacket isn’t seam-taped for sustained rainfall but it’s certainly mizzle-proof enough to get you off the hill before any damp seeps in. It’s even been whispered that the 0Hiro would 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. 

Key features
  • Primaloft® Hi-Loft Ultra retains over 85% of its insulating value when wet and survives repeated compressions without losing loft

Environmental Considerations

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

As part of our continuing effort to remove long-chain flurocarbons from our outer garments, we’re now using C0 Durable Water Repellent (DWR) treatments across our insulation range. Despite the slight impact on performance when compared to C6 DWRs, C0 DWRs are non-toxic and completely PFC-free, causing significantly less environmental damage.

Sweet spot

Warmer than my filoment and a good fit. I am 186cm and 75kg and med is a good fit. Warmer than my filoment and the 5k bit means it stays right with UK drizzle, I probably won't use my now and the zip means it can be used as a proper belay jacket. I am knocking a star off because it has been reduced so soon after going on sale.
