This exceptionally warm belay jacket houses our suberp 900 fillpower down in box-wall construction, allowing maximum loft and delivering a TOT* rating of -20°C: very reassuring while belaying on frozen waterfalls. Additionally, this jacket is frequently selected for high-altitude trekking in the Himalayas and Andes due to its versatility, its light weight, and its warmth.
Minimal features and a trim fit mean the Delta can be used in classic belay mode – over the harness when you stop moving – or under the harness for light, easy movement while climbing in deep cold. A fully adjustable, helmet-compatible hood is a given on a serious belay jacket; we’ve teamed it with a high front zip to provide maximum warmth and lock out gnarly conditions. Although clean and uncluttered, there’s no compromise on technical function: features such as high-viz reflective strips for location, glove friendly zip pulls and a clip loop to secure the jacket at change-overs make for a high-spec mountain workhorse.
Down filled Belay jackets really come into their own in dry cold, but obviously the conditions can change: water-resistant protection comes in the shape of Drishell fabric and YKK Aquaguard zips, to guard against damp snow or dripping ice if the temperatures rise. If you know you’re heading for wetter conditions though, take a look at our Primaloft filled Belay Jackets .
Please note: this jacket is designed and sized to be worn over the top of outer layers. It provides additional warmth on cold belays and can be swapped between climbers at pitch change-overs. If you want a trimmer, more athletic fit select the next size down.
£244 less than our standard version.
