Explore 0Hiro insulated 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)

"Excellent fit, and a good balance between performance and style. Serious synthetic jackets for the real cold, but where moisture is managed, are rare. This is a real star performer, having tested it in the notorious cold of the Canadian north in winter."

"Have had this for over a year now and love it. It is the warmest and most comfortable jacket I own. Biggest downside is that I miss it in the summer when it's just too warm to wear it! "
