How to Measure:
For best results, take measurements over your underwear.
Measure under your arms, around the fullest part of your chest.
Measure around your natural waistline, keeping the tape a bit loose.
Measure around the fullest part of your body at the top of your legs.
Using pants that fit well, measure the crotch seam to the bottom of the leg.

Do these have a fly for easy nature breaks?

Hey Rowan, They do indeed! Cheers, Erc Gearhead

I've been wearing these liner bibs under my Chrome bike shorts on both my road and mountain bike rides for the past couple of months and found it to be a super comfortable combo. The fabric breathes well and I really like the padding and how it doesn't extend into the front of the shorts. The swat pockets are awesome also. They can hold a good amount of stuff (gels, snacks, tube, etc.) and because they're affixed to the bibs, nothing moves or shifts around on your back like it sometimes can in the back pockets of a jersey. I first purchased size Medium and ended up getting a Large since the Mediums felt just a little bit short in the body. Highly recommended.

Thank you so much for your review! We really appreciate the feedback. Glad to hear you were able to get the right size.

Specialized nailed it. Truly. An amazing amount of pockets and one of the most breathable bibs I’ve used. I can carry a whole days worth of snacks and my camera all without the need for a hip pack. Easy access for when nature calls, and a nice chamois for a forward position while climbing to earn some turns.

Absolutely incredible! And they didn't put padding in the front! Finally the mountain bike clothing world is starting to make designs that make sense for men. There are a couple other companies doing the abbreviated chamois now and this is the best one I've tried. I tried swat bibs a few years ago and didn't like them, they were heavy and the mesh was stiff and weird fitting. These are light, comfortable, well ventilated. Also they aren't nearly so transparent as the pics make them look. Of course they go under your shorts but I was glad they didn't look goofy like those pictures. The chamois looks and feels thick but on the bike it felt minimal (in a good way). These are even better than the giro liners....which I love! Sizing was definitely on the more relaxed side (a positive).


What are the loops for on the sides on the hips?

I do want to start this review by saying that I am typically not a fan of bibs because the shoulder straps get on my nerves after some time. Surprisingly enough I hardly noticed the straps on these bibs and didn't get bothered by them at all while riding. The three pockets in the back easily have enough room to stash a cliff bar bottle and even my swat deflect jacket when I was not wearing it. Another pro is the bib back pockets are separated from the bottom part of the bib and allow easy access to the pockets if you wanted to throw on a part of shorts over the bibs. My only qualm with these is I feel like the inseam is a little too short for me in a medium and generally wear a 32x32 in pants and feel like the chamois rides pretty tight in the groin region. Also, I did see someone was asking about use for gravel grinding. I took these out for a 30-mile gravel grind split the time between being on road and chunky double track. While on the double track I definitely did wish that I had a thick chamois and would say if you are on a nice forest road they would be fine but if you are looking to grind some chunkier sections of trails a different chamois would provide more relief.

I am primarily a mountain biker and therefore have gotten away with wearing short liners for most of my life without any issues. It was until this season that I fully understood the benefits of wearing bib liners out on the trails. My first few pairs were the Zoic carbon bib liners (with similar storage to swat) and I fell in love. When I got these I thought I would love them even more, but sadly I cannot say that has been the case. From the waist down they are extremely comfortable, I would even say my favorite liner I own. The chamois is honestly the best I have for long days out as it is on the thicker side (not overly thick) and stays in place really well without getting in the way. The material is very lightweight and breathable so they can be worn on the warmest days without any excessive sweating issues. My main issue with these bibs has to do with the placement of the straps. On my other liner bibs, the straps skirt the nipple area perfectly so that I don't have any chafing issues. With these Specialized Mountain Liner Bib Shorts + Swat the straps go directly over my nipples causing some serious issues. Now, this is honestly the first time I have had this issue with any bibs and I was a little surprised. The more I carry in the back swap pockets the worse the issue gets. So If I am wanting to ride in these bibs I do have to wear a base layer. I personally do not love riding in base layers, especially in summer, as I typically run really hot and prefer a single layer up top! So they have been designated my shoulder season and winter bibs so I can wear a base layer underneath.

I'll keep this simple and say these are the best bib liners I own. Pros: Nonintrusive chamois that offers the perfect amount of padding SWAT pockets for days - plenty of storage room for a multitool, snacks, a tube... Breathable lightweight material Cons: - - -

Dan. How is the chamois?? I’m a roadie and I’m thinking of these for gravel days. So more of a roadie position not upright MTB ?? Great simple review
