The
Only way to ensure that the armour is where it should be. I’m a daily rider and it takes another 40 seconds to put them on but they are always over the need. Don’t dress for the ride, dress for the slide. You don’t need insurance until you really need insurance.

Works well for all day riding
Purchased these knee pads for being out all day on different road surfaces. I pared them with a padded compression short under baggy motorcycle jeans. Works great with no issues.

Good pads
All around good fit, light and I far prefer the 2 straps as opposed to the sock style pads, far less hot. Will buy again once I've killed them.

Easy to use and comfortable
I use these on my cruiser. I got tired of built in knee armour that hurts your knees and does not stay place. Alpinestars Bionic Plus Knee Guards are comfortable and easy to put on and take off. They stay in place more or less. Sometimes you have to adjust them but over all not bad.
