I have a pair of grey and red Klim Baja S4 gloves size M. From the website: The chassis is made from a 500 denier stretch micromesh. Laid over the mesh base are panels of perforated leather for extra strength. Across the knuckles you get a large TPU protector that is also vented for extra airflow. On the base of the palm there’s an XRD foam pad for comfort and protection. There’s an extra layer of leather on the palm for abrasion resistance. The forefingers are touchscreen sensitive. I bought these last year for wearing in the hot weather in Spain as they flow a lot of air but I found them just a little too tight. Only worn twice, I thought they might loosen up but then I got a different pair on a special offer which fit better. Looking for £45 posted, they normally retail for £68.
Open to an offer on these before they go on eBay. When I say the are tight I think it’s mostly my busted thumb that they were tight on, unless you struggle to get a medium on they should be ok
