Standard UK menswear conventions. Knitwear is usually cut with a little more room; jackets are cut to go over a shirt or a light jumper. Some of our styles are sized M–3XL only — the chips above show what this style comes in.
How to measure: Chest — around the fullest part, under the arms, tape level and snug but not tight.

When the Forecast Can't Decide, You're Already Covered
Weather happens. Your plans shouldn't change for it. The Summit is a light, practical layer with a hood that sits clean at the collar, adjustable cuffs and hem and three zip pockets, and it rolls into a bag for the days that might turn.

Why You'll Love It:
- Hood Built In – Pull it up when the rain starts and let it sit neatly at the collar when it stops.
- Full Zip Front – Zip it to the chin against the wind, or wear it open when the sun breaks through.
- Zip Chest Pocket – A secure spot for your phone or keys, with two side pockets for your hands.
- Adjustable Cuffs and Hem – Seal out draughts and tune the fit to what you're wearing underneath.
- Packs Away Easily – Rolls into a bag or rucksack, so it's always there when you need it.
How to wear it: Throw it over a hoodie with jeans and trainers for a weekend walk, or over a knit and chinos for the commute. Choose black, blue or khaki.
For the man who'd rather be prepared than caught out. Machine wash cold and hang dry; a reproofing spray once a year keeps it at its best if you wear it hard.
