||I am a male of 1.83 m tall, about 69 kg. According to the sizing table I should order these protectors in size L. But I ordered size M instead, based on some reviews I read, and also my experience with previous padding (different brand) that the fit tends to loosen over time. This was a good decision: the fit is tight (when new) but not uncomfortable. Importantly, I don't think the protectors will slide off my knees or elbows in case of a fall. (My sport in unicycling on the road.) The equipment looks sturdy and well-made. I should add that I don't use the wrist protectors, they don't cover enough for my liking. I got a separate pair of half-fingered gloves instead. But even when using only two-thirds of what I paid for, I think it is money well spent.
In summary: five stars, but don't buy too large.
