Alternative Bib Shorts
Bibs with a minimalist look for long summer rides at a high pace push the boundaries of recycled materials.
The shorts adapt to your optimal riding position without restricting mobility thanks to the high-stretch compression fabrics. The Elastic Interface liner ensures maximum comfort even on the longest days in the saddle, when the sun doesn’t set until late in the evening. Breathability is accentuated by perforated suspenders for optimal moisture wicking during high performance. The Alternative collection is designed with the intention of becoming a cycling brand with a low impact on the environment. A whole new perspective on performance, durability and sustainability.

Great Quality, very tight and long
Got the bibs to complete the alternative kit. The quality of material feels great, and chamois is comfortable. I did not expect the bib shorts to be so long or so tight. By the size chart I should have gotten a XS, but I opted for a S as I do with many other brands (I have fairly large/muscular quadraceps and glutes). Bibs come down just above my knee cap (175cm tall and 65kg & 73.6cm inseam), and very tight around my body. I personally love a bib with shorter legs (like rapha core or Maap team bib), but maybe this is a Euro style...? Anyway, very pleased with the style and quality, and I have my own preferences on bib fittings, but still a great bib short. Should I have gone with a XS?Show full review -

Comfortable, but maybe too tight
Quality is great like always, but bottom straps around legs are maybe too tight to me. I am 182cm ~75kg and my hips are ~99cm so based on size table I should take M (like tights which I have), but its very hard to take it over legs, because leg straps are tight even over my calves and I am not such a muscled sprinter :-) Maybe it will fix after few ridesShow full review -

Feels very good, looks good, but I had quality issues
Looks indeed amazing, style, good materials, very soft, and runs bigger than usual. I have older version size L, I am 188cm and 90kg, and M fitted perfectly. Also straps are very good, and even cycling in +35C I survived. Now, unfortunately I had 2 linings opened after one sensitive washing, so I had to send it back for repair, took a few weeks as they did not have the same model/size to replace, and so far I was also not even offered a discount. The customer service did not even bother to check my original order for the delivery address, and has asked me twice, so I am quite disappointed, given the price of the goods, you expect premium service when buying such quality/price of cycling equipment. For the sustainability definitely I will keep buying from Isadore, as it is the only affordable on this category, if you compare to MAAP or PSN, that is out of regular people's league.Show full review -

Great fitting shorts with a very comfortable pad
Really pleased with the fit, feel and colour of these shorts (178cm, 76kg, size medium). The pad is extremely comfortable without being bulky and causes me no soreness even after 6 or 7 hour rides, whilst the lycra is soft and fits snugly without feeling over-tight or compressive. My personal preference is for a high bib front, and the Alternative Bibs provide that, but the soft material means it's still easy to pull down for comfort breaks. Highly recommended.Show full review -

Lovely bibs
At 185cm 90kg the size guide said XL, and my other Isadore bibs fit well as XL, but these feel way too big and I should have picked L. The padding is good, but for me it feels like in a slightly wrong position. Sadly I only realized after riding with them.Show full review -

Wow! These bibs are a revelation
I've been buying Isadore apparel for years now and I'm a loyal customer. Design, quality, price point are top notch. I bought bib shorts from Isadore before and haven't been disappointed. I bought the previous model of these shorts and loved the fit. But this season's version are amazing. The biggest change is the level of compression due to the new material choice. The first time I tried them on I was a bit nervous as they're a tight fit but now after a few wears they slip right now and feel amazing when I ride. I love Isadore for their bold color choices and these are are no exception. Now all I want to wear are high compression shorts when I ride. I'm 5' 11" (180 cm) and wear a Large.Show full review -

They’re tight…..
Wow……silky smooth, feel great and using the fit guide I was a medium, but getting them on is quite a challenge. I wouldn’t say I have large thighs, but these shorts are barely wide enough to get over my knees….then the fun begins. A good few minutes of nipping the material between my fingers before ‘gently’ feeding them up little by little until they’re somewhere near fitting. On with the braces, then a few more finer adjustments and they’re on. In hindsight I should maybe have gone for a large, but what I will say is they are very comfortable when you eventually get them on. Only worn them twice so I’m hoping they’ll maybe give a little over time.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 -

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 -

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 -

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 -
