Warmbac Warmtex knee pads, plain strap
High spec and very tough knee pads. Outer surface coated with very durable warmtex material. Inner surface is higher friction double diamond neoprene to help keep kneepads in place.
Top tip: glue a *small* patch of spare neoprene (part of an old wetsock, perhaps)on the inside of the kneepad, as soon as you can after purchase. Just enough to cover the lower joint, not so much as to cause the kneepad to become inflexible and gape at the sides (which would allow gravel in). Your knees will love you for it in future years!
