Also available in custom sizes. We make clothing to order, so if you’re not a standard size we can make it to fit. To order a non-standard custom size, select the Custom Sizing tab, choose your body width, and then the body/arm lengths, shorter or longer, that work for you. A custom size takes us a little longer (typically two weeks longer) to make and, because it’s personalized, it’s non-returnable and our customer loyalty scheme can’t be applied. 

This little scrap of fabric unfolds into a pull-on which will cut out the wind and transform the performance of your fleece. Walking, biking, camping, this may be the most effective few grams of comfort you can take with you. A fold-down hood provides an extra degree of warmth when you need it.

Available in three fabrics:

  • Standard in superlight MX at 87gm
  • In water-resistant Drishell at 126gm
  • In lightweight M1 at 102gm


Water-resistant Drishell outer fabric (weight: 54 gsm)

Ripstop nylon with an ultralight coating: achieves total windblock, along with high breathability and superior water resistance. Superbly efficient for a very light overall fabric weight.

Lightweight M1 fabric (weight: 39 gsm)

Lightweight silky microfibre. This close-weave 20 denier fabric is fully downproof, but also light and flexible enough to allow the down full loft. A reliable performer that has been the basis for much of our lightweight gear for some time.

Superlight MX fabric (weight: 32 gsm)

A mini-ripstop nylon with excellent tear strength, MX is the pick of the superfine 15 denier downproof materials. We have tested lighter fabrics, but most have had significant drawbacks, while our confidence in MX is based on several years of extensive use in both our ultralight and our high mountain gear.

"The windsmock was a valuable piece of kit. I managed to do without a heavy waterproof shell for the whole season in favour of the Drishell Windsmock. It layered well and compressed down to nothing, breathed exceptionally well and shed snow and light rain. Awesome."
