OVERVIEW: This ultra-endurance bib is the ideal choice for those who want guaranteed comfort on extreme adventures, all-day rides and races. The 2nd Generation Elastic Interface® Endurance Anatomic Super Air chamois was uniquely designed to Pactimo's strict comfort specifications for a long distance pad. The extremely durable Cerami–K fabric, noted by its unique dotted pattern,  provides uninhibited movement, long distance comfort and heat dissipation during maximum exertion. Extensive engineering and rigorous testing has resulted in uppers that will completely disappear during your ride, thanks to a combination of breathable/lightweight mesh around the waist and raw-edge cut, double-knit straps. Single layer, mesh knit leg bands guarantee a slip-free fit while also allowing for moisture movement away from the skin.



CLIP&PIT™: With our easy Clip&Pit™ design you can answer the call of nature without having to remove your jersey to pull off bibs straps, which is typically a deterrent to wearing bibs. Just unclip the chest strap and the stretchy construction of the uppers and waist girdle allow you to easily pull the bib down as you bend into the natural position for relieving yourself. Learn More

Cerami–K Fabric: Constructed with Swiss-milled, ceramic-print fabric that is super lightweight and extremely durable while also offering and even-compression fit for all day support and heat dissipation.

Minimal Uppers:The redesigned uppers are not only extremely supportive, but incredibly comfortable as well, so much so, that we say they will disappear during your ride. To accomplish this, we've used a combination of breathable/lightweight mesh around the waist and raw-edge cut, double-knit fabric for the shoulders and front straps.

Ultra-Endurance Chamois: Guaranteed to provide unparalleled comfort for 12+ hour activities, this Stratos Bib includes the 2nd generation Endurance Anatomic Super Air chamois. Our development team worked specifically with the experts at Elastic Interface® to custom-design this updated version of our award-winning 12-hour chamois to make it even better. The new skin-contact fabric is Recycled Eco X-Fifty, which has a textured design to aid in moisture transfer and unparalleled all-day comfort over any terrain.


The following OFF BODY inseam lengths were measured on a garment at rest. They may not exactly reflect the ACTIVE inseam length when the garment is being worn due to the combined effects of the 1) the riders's torso and femur length, 2) stretchiness of the material, and 3) the rider's leg musculature.

Measuring Tips 


Using a soft measuring tape, bring the tape across your back under each arm, around the front. For women, measure the widest point of the bust. For men, measure around the largest part of your chest.


Bend to one side to find natural indentation in torso. This is your natural waist. Run tape around waistline, keeping tape parallel with floor. 


Stand on a level surface with feet together. Measure around fullest part of hips and bottom (approximately 7" - 9" below waistline), keeping tape parallel with floor.

Just as advertised

The chamois is the bomb! I love the contoured and thoughtfully placed levels of padding. The transition from pad to short is thin and well stitched. I have not had to use the pit stop feature yet but I have done a trial run and it works! It would have been nice if the front came up a little bit further, but I understand for the pit stop to work they can't be any higher. All the more motivation to keep my belly fat in check! I am typically a size 4 in most clothing and the size small fits nice. I do prefer a tighter fit for the compression and this sizing allows for that.

They're good bibs, but not $200 bibs

I bought these based on the positive feedback of an ultra-distance rider I know. I think they're good bibs. The fabric is a little weird and I don't know if I love the texture, but the fit is nice. I've worn them on multiple 100+ mile rides, and for me, they're not 12-hour bibs. That being said, they're still nice and comfortable, and I appreciate companies finally making bathroom-friendly bibs for women instead of calling them "brevet bibs" without that feature * cough * RAPHA * cough * (5'3, 125 lb, small bibs, great fit)

Great bib shorts, just a little long

I’m 5’2” and I ordered a medium. Love the bib shorts and the padding is comfortable on long rides. The Clip&Pit is still a little hard to use. I feel like I have to be almost upside down so that I don’t get the chamois wet when going to the bathroom. If they can make the material a little more stretchier so it goes down easier, that would be great! Also, the shorts are too long for my liking.

Great bibs!

Works really well for really long rides- as the bibs advertise. Fits as expected- I got a medium and I'm 6'0" 146 lbs. Honestly can't say enough about the comfortability of the bibs. Will absolutely be getting another pair.

12 hour padding is a misnomer

I purchased this bib with hopeful optimism - they had me at 12 hour. Sadly, the padding didn’t live up to the promise. Wore them on a relatively flat 67 mile ride and was very disappointed in the comfort level. I have other bike shorts that are far more comfortable for longer distances.
