Travel tshirts for Men

Hello Travellers/Wanderers,

I would really like your advice as to what type of tshirts would you buy while on a travel, it could be a road trip, airport journey, trekking, hiking, camping etc. I know there is no specific answer however what would you prefer.

1) Which fabrics do you prefer while travelling? 100% cotton, 95% cotton/5% Elastan, 100% polyester dri-fit?
2) Solid tshirt or printed (slogan) tshirt?
3) Good fit tshirt or comfy, loose fit tshirt?

Your advice will be extremely helpful and will be taken into consideration.
