Bust: Place your tape measure across your back, underneath your arms and then across the widest part on your bust. Don't 'squash' yourself.
Arm length: Measure from the back of your neck to the top of your shoulders, to your elbow and down to your wrist bone
Waist: Measure the smallest part of your torso
Hip: Place your measuring tape around your body at the fullest part of your hip, feet together
In instances when your body measurements for bust and height (or waist and hip) are in two different suggested sizes, Icebreaker recommends going with the size from your bust (or hip) measurement.
The warm Merino 260 Vertex LS Glacial Flow Crewe is a great looking base-layer top that also works as a stand-alone cosy top for post-adventure relaxing or as a midlayer when temperatures really drop. It's made with 100% Merino wool with an all-over camo pattern that references the fluid pattern found in the reflection of a glacial lake. Other features include underarm gussets for extra mobility and offset, flatlock seams for comfort.

Technologies
Merino wool is super lightweight, soft, moisture-wicking, non-itchy, non-clammy, warm in the cold and cool in the heat, and has a miraculous ability to resist odour. Because it was made in the mountains rather than in a petrochemical laboratory. It's naturally renewable, recyclable and biodegradable.
The smaller the micron, the finer the fibre, the softer it feels. The diameter of a Merino fibre is measured in microns – where one micron equals one millionth of a metre. Icebreaker's Merino fibres range from 15.5 to 23.5 microns to ensure a soft hand feel across our skin to outer layers. Finer fibres feel softer because they bend more easily when in contact with the skin.
Icebreaker next-to-skin layers: 15.5-18.5 micron
Icebreaker mid layers: 18.6-22.5 micron
Icebreaker outer layers: 22.6-23 micron
Synthetic fibres: 30 micron
Traditional wool fibre: 50 micron
Human hair: 70 micron
