Measuring tips

Take your actual body measurements as they are more accurate than measuring over your clothes or shoes.

Collar: measure around the base of the neck where the collar sits.

Chest: measure the chest at the fullest part, placing the tape close up under the arms.

Waist: measure the natural waistline.

Jacket Length: measure from the centre back of your neck to your hemline. Then length measurement will vary depending on the style.

My cycling essential

I bought it for cycling although it is a mountain jacket. I can cycle in -2 degrees (this morning in London) with just a thin base layer. It can even provide basic rain/showers protection. Incredible.

Incredible protection for such a thin layer!

Fantastic 2nd skin layer with a super thin thermal lining bonded directly onto the pertex material.
I've used this on winter runs in Scotland and the Alps with only a thin base layer, incredibly warm!
