Castelli Polare 4 BibTight - Men's

The Polare are Castelli's warmest bib tights. Upgraded with a clever new Polartec fabric that is incredible breathable and fully windproof; the Polare 4 do more than ever to keep the elements out and your hard earned heat, in. The duo-layer fabric used on the back offers great insulation and temperature regulation. A brushed fleece interior offers yet another layer of warmth, and full-back bib straps stay put and make layering a low-bulk affair.

• 3-layer Polartec® AirCore front panel is completely windproof while still being exceptionally breathable, water-resistant, and has a comfortable stretch.
• Thermoflex Core 2 fabric is made from polyester, nylon, and Lycra, trapping warm air in the layer closest to your body, while wicking moisture to a top layer to get it off your skin. Highly elastic for an exceptional fit
• Kiss Air2 chamois features a soft, seamless skin care layer that adapts to your anatomy for no-chafe comfort. The variable-thickness pad cushions your sensitive parts to keep you comfortable on the saddle
• Reflective strips above knees seem to flash while on the move and help keep you seen
• Ankle zips help with kitting up and kitting down
• Castelli rates these as best between -5°C to 5°C
