I wore boardshorts for ages, still do sometimes. seat can wear a little quicker, but it was the stitching that gave way on my enduras – which were thick, stiff and heavy and pulled on the thighs when pedalling.
Current favourite is a pair of Oakley shorts I picked up in TK Max for £18. Soft, thin fabric, dries very quickly, that’s wearing much better than expected.
Only logo is black embroidered, on black fabric. Otherwise a normal pair of casual shorts. Don’t look silly off the bike, like a junior stormtrooper. One of those purchases where I wish I’d bought more of at the time.
Edit: further to the above, I just went looking for a pair online. They might even be golf shorts! 😆
