Shouldn't the perfect travel shirt be synthetic enough not to crease, but not so synthetic that it gets smelly too quickly?
For example, Rohan shirts don't crease &don't need ironing but are very polyester heavy & need washing often (bit like the classic helly hansen tshirts, but not quite as bad). I have a patagonia shirt which is quite cottony but creases heavily. Merino wool satisfies both requirements for winter tshirts, but no use for summer shirts.
I've only ever found one shirt which satisfies both criteria, but it was a one off by Fosters menswear I found in a charity shop - don't think they even exist any more.. I've never found another shirt like it. Anyone on here have any top tips?
