EXCEL SPORTS BOULDER

These cool weather bib shorts use Nanoflex water-repellent fabric which is one of those fabrics that seems miraculous. On a dry day it's as warm and breathable as Castelli's normal Thermoflex fabric, but when it rains the water just runs off, thanks to five-phase nanotechnology treatment.

Castelli uses an innovative construction that minimizes seams to keep you as dry as possible. While it's not 100% waterproof, it's the best solution out there for staying comfortable in any condition. On a wet day, pair the Claudio bibshorts with a set of knee or leg warmers and you'll feel almost the same warmth as with a pair of tights.

The KISS3 seat pad features an anatomic shape to conform to your body and ultimately increase your comfort. A continuously variable thickness eliminates the odd sensation of "thick here, thin there" that you may have seen before with other dual-density pads. The brushed microfiber cover cuts down on chafing and features a bacteriostatic treatment to reduce the likelihood of saddle sores.
