I’ve recently purchased both these bits of kit...the knee pads seem to be of strong padded plastic, the gloves are a gym-type, that have a wraparound strap around the wrist for good fit...great for strengthening hands for hard work...better than the cheap thin garden gloves.
Knees and hands are important to protect as best as possible, if a practical person, obviously they get battered, bruised and cut on occasions
A bit of protective gear doesn’t go amiss, but don’t skimp on flimsy stuff, defeats the purpose then
