Universal summer bibs made from recycled materials
Love the new colours. Sizing seems to be a little bit on the smaller side (not as forgiving on the thighs) compared to the previous release but all in all, quality bib with such a soft feel.
Product description
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.
Temperature 16°C to 32°C
Breathability 6/6
Chamois Protection Level 6/6
Abrasion resistance 5/6

Go to bib in the range for hot humid weather
Love the new colours. Sizing seems to be a little bit on the smaller side (not as forgiving on the thighs) compared to the previous release but all in all, quality bib with such a soft feel.Show full review -
Quality excelent but the size is tricky
Tha tailoring and the material quality is professional. Unfortunatelly the sizeing is tricky I am 177cm and 68kg with muscular lower body. The size S is definitly small, i sended it back.. The size M is perfect. Has a really competitive look. I love it!Show full review -
Best comfort and padding
Top-notch padding from Elastic Interface, very comfortable fit, great for hot summer days. Only one question - how long these bibs could last?Show full review -

Great!
Fantastic lightweight Bib, could be a bit tighter around the thigs, compared to the echalon Bib.Show full review -
Stylish and Excellent Fit
These bib shorts are simply excellent all around. They are stylish and fit perfectly. I think they are ideal for Spring/Summer, but I've worn them already during our relatively mild late California Fall and they are fine. The cashew color is unique and versatile. I'm 173cm & 69kg and I ordered them in size S--perfect fit!Show full review -
Tolle Hose und geniale Optik
Bin über eine Empfehlung auf Isadore gekommen und bin von der Hose total begeistert. normalerweise trage ich Größe L. Bei Isadore muss man immer eine Größe kleiner bestellen. Wenn man das weiß die perfekte Hose.Show full review -
Best summer bibs
I have the earlier version Alternative bibs in black, which are my go-to summer bib. This newer version is slightly better. The recycled chamois pad is the same as the older version and will quite happily do 100 mile+ rides - what more do you want? The new version has better straps, with a less stretchy tape used to support the bib which should presumably reduce sagging. The construction of the leg hem seems to be different - instead of a gripper "band" which is almost like a cuff, they seem to have put a gripper "print" over a wider area. You can roll up the edges up, sort of like a laser-cut sleeve on a jersey. However, they do stay in place so this is different, not worse. As with most pale bib shorts, the "Cashew" version is slightly see-through, though not quite obscene. 187cm 75kg size L.Show full review -
My favourite bibs
On my second pair of the Alternative Bib Shorts because I love my first pair so much. Really comfortable pad for long distances. My original pair are still almost as good as new after two years of riding and I don't doubt these will prove as durable too. The new design is maybe not quite as compressive as my older pair but I think Isadore have altered their sizing slightly and I should have sized down. 179cm and 67kg and medium is fine but will go with small next time which is what the fit guide suggests.Show full review -

Super comfy and well fitting!
Super comfy and well fitting! I have been a die hard Rapha fan for last couple of years but after trying these bibs I dont think I will go back. You getting so much more value for your money from Isadore. These are my favorite bibs now :)Show full review -
Super cool
I really love these bibs; firstly they look great with super stylish graphics, but they also wear well. The straps are so comfortable and the pad keeps me going for ages.Show full review -
High quality
The bib shorts are superbly made. The fabric is really thin and feels soft, the overall quality seems to be very good. I could not wear them on bike, since they are a bit too big for my flat bum. Gip measurement! Even following the size table was not as successful for me as I had wished. But this could be a particular issue regarding individual shape. All in all if the size is right, these bib shorts are great.Show full review -
Alternative Bib Shorts
My favourite shorts and the cashew colourway looks really good. These are very comfy. 178 cm 76kg using size L but could maybe go to a M. 30km a day.Show full review -
great
chamois is comfy and seems of good quality. I have done a couple of all-day rides in warm conditions in it, no chafing anywhere, much comfort. Size L is ok for me (190 cm, 85 kg).Show full review -
Comfort and style
Love the new colour and the bib design. Definitely and upgrade from the previous models. Nice fabric too!Show full review -
Very comfy, high quality bibs!
I've been now riding 200+ km in these bibs and they are very comfortable. Clearly designed for warmer weather and they breath well, for below 10 degrees (Celsius) I would recommend something warmer. Size seems to be on point. Also I like the colors. Can totally recommend these!Show full review -
Feels great
The bib fits me very good (snug) and feels amazing compared to my other bibs. I have size L at 1.90 m and 82 kg. Only problem is that the reflective logo on one side is already starting to peel off after the first ride but I can live with that.Show full review -

Best shorts that I've owned, recently ordered my second pair. Fit and comfort is great (size L, 86 kgs, 185 cm).Show full review -
Simply the best bib shorts for me!
The fit is extraordinary. Chamois is just perfect for my body. The recycled materials are just perfect, you can't find any difference from non-recylcled. Long riding just became a pure joy for me, thanks to Isadore!Show full review -
high quality
fast delivery, few and compostable packaging material. shorts look very well made. finally a size M bib short that fits me - 177cm, 70 kgShow full review -
Yess!!!
My first Bibs from Isadore and they're absolute fantastic!!! Slim fit but not too tight. I'm 1,93 m at 86 kg and i bought size XL. Longer Rides (everything over 100 km) are more easy to achive!Show full review -
Great bib, extremely comfortable
my second bibs from Isadore, own already one for colder weather. the chamois are amazingly comfortable, i've been using some Nalini professional in the past, and these one can compete and beat. great for long rides, climbing, hot days. 193 cm and 88 kg, XL fit best. Excellent crafting, high-end product.Show full review -
Great shorts
This is the third pair of Isadore shorts I have purchased and they are the best so far. Beautifully made, super comfortable and really stylish. The pad is one the best I have experienced. The added bonus of these shorts is the eco credentials. Good work IsadoreShow full review -

Outstanding quality and incredible design. I thought the suspenders where a bit scratchy at first, but it worked out perfectly allright. 178cm and 86kg - size L fits perfect. If I could change one thing, it would be more compressionShow full review -
Great
These are the best summer bib shorts I have. The padding is not very thick bit very effective. The fabric is breathable and feels quite nice on skin. I have bought recently a second pair of them and ride only them for now. No better reference needed. 10/10 or even 11/10Show full review -

Paw
Exceptional. Being more sensitive to saddle and bib shorts issues, I am totally convinced, that these are the best bib shorts I have ever owned. They are light, breathable and the most important, the pad is spot on. My first ride was about 100 km long, I could easily find my optimal position and did not experience chafing or whatsoever. I am happy with them and wait for the size S being back in stock.Show full review -
Super fit, super soft and stretchy material and seat pad, gentle compression
Super bib and beautiful too. For reference, I'm 194cm tall, 86kg, 34 in jeans. I tried XL and L. At first I thought XL is right, but the material is soft and stretchy that I ended up with L, which is great. For comparison I have got CASTELLI FREE AERO Bibs in XL and the Fabric and Seat pad on Isadore Alternative bib is softer. I usually ride for 2h and overall Isadore Alternative bib feels more comfortable on bike. I would buy again. This is my third bib from Isadore and I will order one more soon.Show full review -
Anro
Sehr gute Hose aus angenehmem Material. Trägergurte und Schnitt sind echt luftig für Sommerfahrten, Oberkörper fühlt sich frei an. Polster auch sehr gut, obwohl ich etwas Bedenken hatte, weil es sich recht dünn anfühlt. Lediglich die Beinlänge ist für meinen Geschmack etwas zu lang. Kaufempfehlung. 181 cm, 74 KG - Größe M passt prima.Show full review -
Ralf
The pants themselves are really great, they fit very well and the padding is great. However, I have big problems with the seams, as they scratch a lot and even scraped the skin after longer rides. The problem occurs primarily at the point where the front thigh meets the hip (both sides), since the seam is constantly moving here while driving. I have the same problem with the alternative 3/4 bib shorts. I now help myself by treating the seams with chamois cream the day before a longer ride.Show full review

Najlepšie nohavice ktoré som mal.
V priebehu 15 rokov cyklistiky som vyskúšal mnohé kraťasi. Tieto sú však jednoznačne najpohodlnnejšie. 7 hodinová jazda bez akého koľvek náznaku bolavých sedací partií. Pecka! Krásne vypracované!Show full review -
Roger
Absolutely great bib shorts! I love the pad, the length and the size. I am 1.88m, 76kg and a waist of 87cm. I ordered an L, it sits race tight, but very comfortable. I got long legs and this bib has the right length for my legs. I also have a Signature bib short form Isadore, but I prefer this bib short over the Signature bib.Show full review -
Super

Comfy warm weather bibs with too short legs
I really like the product except for the legs being too short for my liking. It'd be better if the cut would allow the legs to be 3-5cm longer as with other "comparable" brands. Thin matieral that sits nicely.Show full review
