Sizing chart is very accurate, but if in doubt I recommend going up a size. May not be as warm as you expect of a "fleecy" jersey, So I would say that it HAS to be worn over a base layer or under a light weight jacket. It's early days usage wise, but it looks like it is very good quality.

gloves too small but staff very happy to exchange, very good service and great to be able to talk to staff on phone thanks

Wore it the first time today in Perth in 8C over along sleeve jersey.
The first 15 minutes it was toastie warm. After about 20 minutes a slight chill but it was nice as it kept my operating temp even. After 23kms and 51 minutes arrived at work and was surprised at how good I felt. Minimal sweat, good stretch and very comfortable.. Very happy with it.
Overall very happy with the product and service from cycling sports.

True fit, comfortable and flattering style with the best chamois I have experienced! Great now the mornings are cooler.

Great for my winter commute - warm and comfortable
