Gul Code Zero Pro Sailing Knee Pads, so you don't go weak at the knees. Flexible and durable 3-4mm double lined neoprene with elasticated fully adjustable velcro straps to achieve optimum fit and comfort.  Featuring Kevlar finish to help protect the knees from abrasion. Very functional, practical and extremely popular knee pads. These Knee pads have already proven to be extremely popular for any novice paddleboarding.

The sizing can be a little subjective depending on whether you are wanting to wear the knee pads over a sailing drysuit or a 2mm or 5mm wetsuit, for example, or in the case of Stand-Up Paddle boarding, often over bare knees.  Due to being made of stretchy neoprene and the available velcro adjustment they can be a fairly accommodating and an adaptable fit.
