“Great light weight gilet. This is my second one- and this is probably one of my favourite pieces of kit. Useful for warm up on colder early starts during summer and also helps to layer over a thermal jersey for warmth during the entire ride in fall or early spring. Honestly, I’ve worth this along with a heavier jersey and merino baselayer and been comfortable in 4-5 degree Celsius weather. It fits snug, I typically wear a small MAAP jersey and I wear the gilet in medium. My other version of this gilet is size large and thus fits well over a heavier fabric jersey. I’m ~69kg and 179cm”
