Women's Echelon Aero Bib Shorts
Aerodynamic racing shorts made for maximum performance during summer rides.
The fit with a higher compression rate and extended legs is ideal for racing conditions and gives a second-skin feel. Shorts are made of two stretch materials with a high proportion of recycled materials. It is wind tunnel tested to reduce air resistance at speeds higher than 36 km/h. The breathable fabric wicks away sweat and regulates temperature during intense training sessions. The innovative design of the insert increases comfort regardless of whether you are sitting on the bike in an aerodynamic position or analyzing your ride in a cafe. It is perforated in the most crucial areas to support air ventilation and to secure comfort even over extremely long distances.

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 -

Super comfortable
I've bought a few different bib shorts from Isadore so my expectations were high - I was not disappointed. The fit is snug but perfect for long rides, they are as comfortable at the end of the day as they are at the beginning. The only slight downside is that the shoulder straps & detailing are white (not turquoise as in the picture).Show full review -

Best bib shorts I ever had
Excellent bibs — no wonder this is my third pair! At first, I was a bit afraid of the compression fit because when you put them on, it feels a bit strange to just walk. However, once you get on a bike, you immediately discover their true power. Simply put: they feel like a second skin, and the brown 'earth' color is practical and uncommon—great!Show full review -

Superb quality
Love the materials and quality, especially that textured fabric. The only thing you should consider when buying these is the length, my legs are on the shorter side, so they end just above the knee (182cm/80kg, size M).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 -
