"Chose this because 2 sizes offered, I'm at the top end of small. Ordered for next day collection but was not asked what size during ordering. Picked up in-store, size label said small but when I tried it on the chap behind the counter just laughed. Not even remotely close even with the strap as tight a possible. Money refunded.
Otherwise on a very quick inspection the cap looked OK, but that is irrelevant if the sizing is wrong. For PPE that could be dangerous."
