Echelon Aero Bib Shorts
Built for high-speed performance, the Echelon Aero Bib Shorts combine aerodynamic fabrics with a compressive race fit.
Designed for high-velocity performance, the Echelon Aero Bib Shorts feature a race-optimized aerodynamic profile paired with a lightweight brace construction. Developed for riders who demand speed and efficiency, the bib shorts use advanced fabric engineering and precision construction to reduce drag while maintaining long-distance comfort.
The shorts are crafted from two high-density Italian-woven fabrics with a high elastane content, delivering exceptional stretch, muscle support, and a stable second-skin fit. The primary fabric features a smooth surface made with biodegradable polyamide, providing a refined feel and helping reduce environmental impact without compromising performance.
Strategically placed panels incorporate a 3D-structured aero surface designed to manipulate airflow and promote laminar flow across the fabric. This structure helps minimize drag at higher speeds while maintaining breathability and comfort during sustained efforts.
At the core sits the Elastic Interface® Hybrid Cell System chamois, strategically perforated to enhance ventilation and provide reliable long-distance support. The leg hem combines a wide silicone elastic band with precision clean-cut edges and printed inner grip, ensuring the shorts stay securely in place while delivering a seamless aerodynamic finish.

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 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 -
