Knees are the first thing to complain when the temperature drops, and Assos has built the Spring Fall Knee Warmers P1 around fixing that problem before it starts. These are midweight knee warmers for riding in the cool, dry conditions of the shoulder seasons, updated with a textile that's more durable and packs down to smaller volume for storing in your pockets. If you've spent years pulling on knee warmers at the trailhead parking lot and stuffing them in a jersey pocket two hours later, this is the P1 update to a piece of kit you probably already own a version of.

Any ride under 15C (60F) really does call for knee warmers, and any rider who's gone out in those temperatures and suffered through stinging, achy knees knows why. The P1 sits in that shoulder-season sweet spot where leg warmers are overkill and bare knees are a mistake — think 50 to 65 degree starts that warm into the 70s, or fall rides that begin chilly and finish in sunshine. Pull them on at the start, peel them off when you stop for coffee, stuff them in a back pocket, and forget they exist.

The construction is built around eliminating the bunching and restriction common with knee protection, providing a high-stretch, comfortably compressive solution to everything from UV exposure and perspiration during summer rides to the lingering chill of exposed knees in early fall and late spring. Regardless of the season, the material serves as a corrective to the temperature, cooling in the heat and warming in cool conditions. That second part matters more than it sounds — these aren't just insulators. The fabric actively moves moisture, which is what keeps you from getting that clammy chill when you transition from climbing in the sun to descending in the shade.... Read More
