Neck warmer can be pulled over your face for more warmth
Flatlock stick reduces friction and abrasion
Mesh armpit adds additional ventilation
Q & A
Warm as warm can be!
Familiarity: I've used it several times
Just got one of these on recommend, and so far it has been excellent! Lightweight yet very toasty. Venting on the sides help regulate temperature, and the front and rear are great for the core. The addition of the neck warmer is excellent, as it can pull up over the ears and lower face for additional warmth. It does run a tad small. I generally wear a large T-shirt, and went XL in this layer.
How to Measure:
For best results, take measurements over your underwear.
Measure under your arms, around the fullest part of your chest.
Measure around your natural waistline, keeping the tape a bit loose.
Measure around the fullest part of your body at the top of your legs.
Using pants that fit well, measure the crotch seam to the bottom of the leg.
