I sweat a lot and I'm looking for T-Shirts. If i search for fabric and summer the recommendation on website about clothes is linen or cotton. They write cotton has: low heat isolation (good in summer) high moisture absorption Now i saw on Amazon this synthetic shirts where everybody in the reviews writes he is wearing it in the summer: https://www.amazon.de/Just-Cool-Performance-T-Shirt-atmungsaktiv/dp/B004NQ2MN0 But all the recommendations on websites are against synthetics because it is not breathable and traps heat. It also does not absorb moisture - so all my sweat runs down to my pants all the time... So why the reviews that this shirts are good in summer?
