Item # ICE0603


End the reign of belly-aching elastic waistbands and learn to climb like the pros.

The next time you find yourself in the drops, mustering all of your being to crest the top of the hill, you'll be glad you slipped into the Icebreaker Circuit Bib Short and discovered its highly breathable, perforated merino wool blend fabric. You'll also feel a little bit of spandex hug your body, as well as its six-paneled construction and chafe-free flatlock seams providing a comfortable ride.

  • Once you get on the saddle, you'll appreciate the integrated Superior Comfort chamois pad that wicks, breathes, and cushions as you ride
  • Natural merino wool provides great moisture-wicking, rapid drying, and odor-resistance for hot to cool days on the road
  • The low-cut design (below belly-button) provides advanced ventilation during gut-wrenching climbs
  • Grippers at leg openings prevent pant migration as you turn your body into a pedaling machine
  • Reflective details increase your chances of being seen and avoided by motorists during early or late rides

How to Measure:
For best results, take measurements over your underwear.
Place the measuring tape around the fullest part of your chest/bust.
Place the measuring tape at your natural waist, the narrowest point on your torso.
Place the measuring tape around the fullest point on your hips.
Choosing the Right Size:
If your measurements are close to two sizes, choose the smaller size for a tighter fit or the larger size for a looser fit.
If your body measurements result in different sizes, we recommend using your chest measurement for tops and your hip measurement for pants.

Oh so awesome

I was skeptical about the Merino Wool in the hot Utah summer, but these shorts have proved to be the best I have ridden. Small hole starting to develop after 3 months of 3-7 days a week of riding, primarily in these, so not surprised. Not thrilled, but will just sew them up and keep on truckin. Chamois is awesome, temperature regulation is awesome, both in cool weather and in that 100 degree summer sun.
Not looking back, great short.
