If your size isnt available - Try the new Speed Pro or Stage Pro Knee guards. 

The Stage Knee guard offers mid-range trail protection in a packable package. D3O® is used for impact protection. D3O® is soft and flexible to keep the guards comfortable while riding, but on impact, the D3O® material hardens to disperse the energy for protection. Slip on a pair and head out to the bike park in confidence.
