Echelon Aero Bib Shorts
Aerodynamic racing shorts for top speed rides
Breathable fabric wicks away sweat and regulates temperature during intense training sessions. Main material was tested in a wind tunnel to reduce air resistance at speeds above 36 km/h. Because of perforations in the most important areas, the premium Italian insert with the Hybrid Cell System is comfortable even when covering long distances. The high-compression cut with elongated legs fits best in the saddle position and creates a second-skin feel. Moreover, the bibs are treated with HeiQ Fresh® and Smart Temp® technologies. HeiQ Fresh® absorbs volatile organic compounds and provides lasting freshness and odor control without silver content. HeiQ Smart Temp® is an intelligent thermoregulation technology for dynamic cooling. It is activated by an increase in body temperature and deactivated after the body has finished cooling down.

The absolute best bib shorts out there
These are hands down the best bibs I habe ever owned. The texture of the material is feels great on the skin and is just the right level of thick so it isn't see-through but extremely breathable at the same time, and just the right amount of compression. I will never buy anything else. I'm 1.75m 65kg and size M fits just right.Show full review -

the design, material, quality is the must
Women, 170cm/65kg/90cm hips - size L a bit loose for above the knee, perfect on the hips. Size M would be perfect for me (my two other bibs from Isadore are of size M). I recommend and will buy these bibs in a smaller size. I couldn't help but fall in love with the design. In the model I ordered (which is not case in the Spring/Autumn 2024), the logo Isadore was smoothly part of the shorts - something I have never seen before on the bibs, and felt in love with it. The quality is undeniably one of the best! I own 3 pieces so far from Isadore (thermal long and short bibs, merino softshell), and you can count on them. Chamonix: felt very good on the touch, and seemed to have a perfect breathability. Unfortunately, the recommended size L was a bit loose at the end of my tights but fitted perfectly on the hips (90 cm). I have wide hips and tights but narrow knees and very small calves.Show full review -

Best Bibs I have worn
High expectations due to the 1) brand and 2) price point, and those expectations were exceeded. They are tight on first wear, and then have been perfect since. The padding is the perfect amount, and felt zero discomfort up to 4hrs so far. I feel FAST in these.Show full review -

Lovely bib shorts
Comfortable bib shorts i enjoyed wearing on a 4-hour ride. Very snug “race” fit, not the thickest of chamois but enough for me. Got a size M for 186cm/77kg/slim build. Look and feel really good. Great purchase and recommended.Show full review -
