Measure Your Chest: Use a measuring tape around the fullest part of your chest, keeping it horizontal and snug but not tight.
Consider Your Riding Gear: Measure while wearing a base layer or shirt you'd typically ride in–especially if you plan to layer underneath.
Allow for Mobility: A good fit should be snug but allow freedom of movement. Remember that armored jackets might feel stiffer at first.
Check Sizing per Brand: Always consult the brand's specific chart–fit can vary by style, cut, and country of origin.

Bought this as I was a little concerned I had nothing between a T-shirt and my Klim Carlsbad jacket. It was great - the jacket and t-shirt were good down to a very wet 11-12°c - added this top and was comfortable down to 5-6°c and it was torrential rain from morning to night. My Klim jacket sleeves also leaked a little and the sleeves on this took 15min to dry resting on radiator.
