Warm, comfy and indestructible

These Bib Shorts are excellent. The fit is supportive and very comfortable (189cm - 79kg - M), the thermal fabric performs beautifully in mild and cold conditions. What truly impressed me, though, was the durability and toughness. I was involved in a hard crash that resulting in a broken pelvis, yet the bib shorts themselves came out of it still intact—no torn seams, no fabric failure.

Perfect Dutch winter bibs

I'm too tall / slim for long leg bibs, so thermal bibs + leg warmers are the way to go for me. These bibs are amazing. Pretty good waterproofing, but of course not 100% (doesn't ever work, and I don't want it). Legs stay warm, also with cold wet weather. Love them!

Very warm and comfy Thermal Bib!

These Thermal Bibs work very well for me from 4 Degrees Celsius up to 15. They are so comfy and I really like that it covers the belly and keeps it warm too ;.] Cruising over muddy gravel or through light rain is completely fine because the wet won't push to the inside of the Bib. There are no real downsides to this Bib - Isadore high quality as ever - but the one thing is the pocket that I don't need and that bears the potential for tearing a hole in the otherwise robust material. And the other thing that prevents me from giving 5 stars: I own the Alternative Thermal Bib Shorts and love them so much, that I really don't understand why Isadore took them out of their product range :-[ Size M fits perfectly for me (181cm/75Kg).

Very versatile bibs for autumn/spring and mild winter days.

These bibs are ideal for chilly mornings and cold and shadowy forest-routes. When the temperatures finally rise during the day or when you hit the sunny side, they don’t get too warm. I’ve used them from 5 up to almost 20 degrees C. And there is buffer towards colder temperatures. With leg/knee warmers they are good for mild and dry winter days. I don’t need the new thigh pocket but it doesn’t bother me either. Maybe it’s good for paper money or some emergency gummy bears. I prefer to keep keys or the phone in the jersey pockets. I’m 179 cm/79 kg and size M fits perfect.

Through the leg

I choose a thermal bib with leg warmer over tights for convenient nature breaks. These have great temperature range and obvious versatility for the other half of the year. I love the structure of the fabric and fit of detailing. At 175cm x70 kg these complement this middle age man in lycra. These have a luxury that my Assos shorts can’t touch.

Top notch quality.

I owned a bunch of winter bibs over the years and this one just feels better than everything I ever owned before. Really nice fit, nice fabric, tight and warm, feels cozy on the skin. For my taste (or body type) the legs could be even longer but thats only my taste. I didn't regret buying these bibs a second.

satisfied with purchase

Very happy with these men’s bibs. They are well insulated, the fabric feels nice on the skin, and the fit is great. There is only one pocket on one side, which takes a bit of getting used to, but it’s not a problem in everyday use. Definitely a good purchase.

Superb as always

I didnt expect anything else tbh ;) As usual, the quality of manufacture and material is superb and the fit is just right for me (179cm, 68kg, Medium). The bib makes especially longer autumn rides so much more pleasant and the pouch on the right leg is a great addition!

Excellent

I was with Isadore from their beginning, stopped for many years and now I am back because I like their stuff, great quality, nice colours and green footprint. I'm 1.83m and 78kg, for me the size M fits perfect. Padding and everything else is perfect.
