Tested where the forecast was wrong.

Every sample goes out with someone who's paid to be on the ridge when it turns. It comes back with notes. The notes become the next version. There's no lab that does that.

The range

Three pieces. One bad day.

A shell, an insulator, a base layer. Worn together they cover the day we designed for. Worn apart they cover the rest.

The one from the brief. Hood that turns with your head. Pockets above the hip belt. Cuffs you can do with gloves on.

Insulator · synthetic · 290 gCol Jacket80 g/m² fill · warm when wet · packs into its pocket

Goes under the shell when it stops, over it when you're stopped. Synthetic because down is a fair-weather friend.

The layer against your skin for fourteen hours. Doesn't smell on day three. Doesn't chafe on day one.

Tests

What we put it through.

Lab first, because the lab is repeatable. Ridge second, because the lab is polite.

Lab
Hydrostatic headWater column on the fabric until it leaks. 28,000 mm means twenty-eight metres of water. Rain in wind is about five.
Lab
Breathability, MVTRGrams of vapour through a square metre in a day. Twenty thousand. Below ten you're wearing a bag.
Lab
Abrasion, 20,000 cyclesPack straps, rock, ice axe. The face fabric has to survive the things you carry.

Sixty days, four peopleReal weather, real sweat, real falls. Every sample comes back with a page of notes and usually a tear we learn from.

The wash testFifty washes at home, no special detergent. The DWR should still bead at fifty. Ours does at seventy.

Sizes XS to XXL, two colours, one of them bright enough to find you. Sixty days to take it somewhere the forecast is wrong. If it lets you down, it comes back and we read the notes.
