Solid Protection, Stays In Place

  • Familiarity: I've used it several times

Great budget knee guards. Cover and fit around the knee well, stays in place even over rough terrain. Too bulky for any climbing but doesn't get in the way on flat or mild climbs.

Fit is It.

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Knee pads are semi-consumable--it is a mistake to buy a pair expecting them to last forever. Better to buy them and put them down in the dirt, and get a new pair when they blow out. These fit well, offer good coverage, and stay in place. And they cost less than a new back tire.
