Bust: Place your tape measure across your back, underneath your arms and then across the widest part on your bust. Don't 'squash' yourself.
Height: This is your true height, without the assistance of shoes
In instances when your body measurements for bust and height are in two different suggested sizes, Icebreaker recommends going with the size from your bust measurement.
The 100% Merino wool 260 Tech LS Crewe heavyweight base layer will keep you warm on your cold-weather adventures. You get all the natural temperature control, breathability, and odour resistance of Merino wool with offset shoulder seams for pack-wearing comfort, flatlock stitching and backward-set side seams for chafe-free comfort, underarm gussets for extra comfort and mobility and a drop tail hem for added cover at your lower back.
