Women's Alternative Bib Shorts
Aerodynamic shorts from sustainable materials for long summer trips with a minimalist look.
Thanks to ultra-fine microfibers with a high proportion of elastane, the main material is extremely compressive and long-lasting, so the bibs hold their shape even after repeated washings. 3D anatomically shaped insole made of high-density biofoam is extremely breathable and comfortable thanks to the perforations. Breathability is accentuated by perforated suspenders for optimal moisture wicking during high performance. Universal bibs fit best in the saddle position and provide enough muscle support for fast-paced cycling as well as all-day rides.

+2 body za rýchlosť a silu
Som veľmi spokojná, toto sú moje druhé bibsy od Isadore. Prvé mám signature vo veľkosti S, tieto som si musela zobrať o číslo väčšie M. Bibsy príjemne sedia, nikde netlačia, neposúvajú sa a sú priedušné. V porovnaní so signature verziou (2023) pri ktorej vôbec necítim že mám na sebe nejaké traky, pri týchto ich občas zaregistrujem, ale nie je to nepríjmené len by som si ideálne želala o nich nevedieť :DShow full review -

Super Langstreckenhose!
Mittlerweile meine liebste Radhose, gerade auch für längere Fahrten (>3h). Polster sitzt super und sorgt für gute Unterstützung, das Material fühlt sich super gut und weich an. Die farbigen Details und das reflektierende Logo gefallen mir persönlich vom Design auch sehr gut. 10/10 Empfehlung!Show full review -

Farby a kvalita
Neviem, kde skor zacat. Krasne farby, prevedenie. Farby pri tejto kolekci (jar/leto 2024) su krasne! ZIal, objednala som si nespravnu velkost - S mi je male. Mam 170 cm/65kg/90cm v bokoch. Ine bibs od Isadore mam M-ko. Cize som v nich nejazdila, ale chamonix vyzerala byt velmi dobra, kvalitna, tak ako ine veci od Isadore. Pripadala mi podobna - ak nie rovnaka -ako pri Alternative Thermal bib shorts. A tie mam odskusane a doporucujem !Show full review -

Best bibs ever
I have bibs from almost all high end makers and these are my favorite bibs for summer riding: I got the nude color for sunny days because black always feels too hot for me. The material is very light compression and the chamois is super thin which I like. Nothing chases or rides up. Only thing about the nude color is that you can totally see the sweat but no big deal for me. Wished they came in a silver or white color as I have all the other colors already.Show full review -

Excellent shorts - like a second skin!
Bought these shorts just before a week’s cycling in Spain. They are flawless! So smooth and comfortable, padding not even noticeable, it’s like wearing a second skin! I’ve had no rubbing or any other issues. Highly recommended!Show full review -

good quality and perfect fit
I used these bibshorts during my 10-days bikepacking trip and I'm very happy with the comfort of the chamois, the light materials of the top, and the perfect fit, because of no unnecessary seems. Furthermore, I love the fact that it's made of recycled materials and produced in Europe. I definetely go buy another pair of these!Show full review -

Great function but bad printing
The Isadore print peels off after a few washes on both legs and unfortunately makes the otherwise very good pants look old.Show full review -

Great chamios
These bib shorts are moderately compressing, with very comfy chamois suitable for longer rides. The straps could be a little longer and made out of different material, they feel kind of scratchy, but with base layer this is not an issue. Overall great shorts.Show full review -

Chamois is too bulky
I really like the use of recycled material. These bibs served me well in gran fondos. One star off because the chamois is a bit too bulky. I'm around 164 cm and 52 kg, bottom heavy . Size S is a tad too tight but not in a way that causes discomfort.Show full review -
