Technical Information

To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092). The lower its resistance, the more the fabric will let water vapour produced by the body escape, and therefore the more breathable it is. For example: RET < 9 = extremely breathable fabric.
Care tips
Machine wash at 30°C. Synthetic programme. Turn the garment inside out. Use minimal laundry detergent. Do not add softener. Line dry in a warm, ventilated area. Do not tumble dry. Do not dry clean. Do not bleach. Do not place on a heater to dry.

Response of the brand
Thank you for your feedback regarding the sizing.
I will share this with the design and production team. As far as I am aware the the cut has not changed from previous years. the LArge size is suited to 39" to 41" chest and for a rider of around 5'11.
Can you DM me with your measurements so that I may share this with the design team?
I look forward to hear from you,

BTWIN 100 Short-Sleeved Cycling Jersey - Blue
Used for 2 to 8 weeks
Great item that fits me very well. Excellent cycling top at a fantastic price. I have also purchased the Black one too. Recommended to anyone.
Don't bother!
I brought two of these shirts one in white and the other in pale blue. Neither fit me properly and the sizing difference between the two (despite them both being 'medium') was ridiculous. The shirts were poor quality and both were returned immediately for a refund. I was totally disappointed with this product and would not recommend it on any level.
Response of the brand
I'm sorry to read that there is a sizing difference between models. I will forward this point on to the design team immediately as this in not normal at all.
I would also be very happy to hear from you regarding the quality as I wish to forward this on as well.
I look forward to hearing from you.
