Kneevo Knee Sleeve
Honestly, I had my doubts. I twisted my knee badly a couple of years ago when I fell through the snow into a creek. Since then when I go hiking, by the time I'm done, my left knee aches and after sitting in the car driving home, it's stiff. I've worn a few knee sleeves that are supposed to help with that, but to no avail. I figured Kneevo's knee sleeve would be the same. So I took it on a 1,600-foot elevation gain hike in the Cascades to find out.
