I've chanced an order of some of these for summer, but I should probably have asked about other people's experience first.
They say they are the same material as the tights, but with extra… something (wicking?) to deal with comfort (sweating.)
There are millions of reviews, mostly talking about tights, but two enthusiastic chub shorts wearers on the first page.
No mention of a gusset on website or reviews, so do we wear knickers underneath?
