“I am from Malaysia am the temp here can get to 40-41 deg C max in the afternoon, but I have been wearing my Thermal LS for most of morning rides and have no problem riding under 37 deg C. The size fits my body type which i am 170 cm tall and have been wearing M size for my clothes. I have no problem zipping up till the end at my neck but the zipper tends to go down during my rides but that's ok. Cheaper to buy directly from M A A P online than local stokist but hope the 15% discount could be extended to other accessories such ass gloves, arm or knee warmers, or even shoes.”
