Troy Lee Designs KG 5400 Knee Guards – sizing?

Anyone got these? They look good and get good reviews, but looking at the sizing chart on CRC I’m on the cusp of XS or S. Anyone use them and give some guidance on how accurate the size charts are? Only CRC seem to do the XS size (but not in stock!).

I bought some mediums based on the size guide and they were bang on, and I usually take a large on 661s.

Size guide was spot on for me too. Don’t just get your “normal” size.

Hmmm, so on the cusp I’d rather go smaller to make sure of a snug fit. Shame only CRC seem to do the XS size and not in stock until September!
