Cover a little more leg on cool-weather rides with the Castelli Men's Ergo Tre Bibknicker. Castelli's updated Kiss3 chamois cushions your ride with multi-density, graduated padding that provides comfort without bulk. The Ergo Tre’s compressive Affinity Lycra fabric provides outstanding comfort and support, while the anatomical eight-panel design gives the knicker a non-restrictive fit. Silicone gel leg grippers hold the short in place so it doesn’t ride or roll up when you’re pumping up a long hill.
