Made from durable materials, the Sylvia Boyleg comprises a Merino wool, Nylon, and Elastane blend of fabrics called Merino Air-Con 140 that help to regulate your body’s temperature for your active lifestyle. It keeps you cool when you’re hot, and warm when it’s cold outside. Additionally, the briefs have no side seams; this is to give you maximum levels of comfort when you wear them. Featuring Mons Royale’s iconic slim-line waistband, the Sylvia Boyleg is truly one of the highest-quality sports briefs on the market.
Fits true to size, nice warm bum whilst jogging in the cold :-D

Bought these as a bloke because I’d been looking for merino briefs to go under shorts for ages and there’s next to nothing available and what there is, they want stupid money for a pair of ballies.
So I got these and at first I thought I was bit ‘on show’ but I’ve worn them a couple of times now and they’re alright, definitely more breathable than synthetic and in summer, that means cooler and drier. No worries.
