A gnat’s whisker short of perfect
Without going into unnecessary detail as to why, I rest on my (very sensitive) knees quite a lot when sailing. Before I got these knee pads I was only able to do this for long by wearing a long-leg wetsuit with 2 extra layers of 3mm neoprene stuffed inside the legs (total 9mm!). With these knee pads I get no knee pains at all even when wearing shorts. They are flexible enough not to restrict movement. Nearly perfect because in an energetic sailing session they can drop down the leg a little, although not enough to expose my kneecaps. The elastic fixing straps could possibly be a tad less elastic, to keep them in place a bit better, that’s all. But still well worth my 5 stars for comfort and effectiveness. I have not had them long enough to be able to comment on their robustness, but they do appear to be tough, and well put together.
