Find my size
Designed for high-output riders who live in their baggies and want serious comfort, the Men's PRO Transfer Liner Bib Shorts are built to deliver pro-level performance beneath your outer layers. Whether you're hitting all-day gravel routes or charging backcountry singletrack, this premium liner gives you chamois-equipped support with minimal bulk and maximum breathability.
Crafted from ultralight Transfer fabric, this bib liner is designed to wick moisture, promote airflow, and maintain a cool, dry feel against your skin, even under heavy effort and hot temps. The form-fitting design disappears under shorts and keeps everything in place without restriction or bunching.
At its core is the PRO Levitate™ chamois, our most advanced multi-density pad, engineered for friction-free comfort, pressure relief, and vibration absorption over long distances. Whether you're seated for hours on a gravel grind or flowing through techy descents, this chamois delivers consistent, ride-long support.
Additional features include drop-in cargo pockets for easy access to snacks or tools, a secure rear lumbar pocket ideal for a base layer stash or hydration, and low-profile silicone leg grippers to prevent riding up under your shell.
Pair it with our Summit Shell Shorts for trail-focused comfort, discover other biking shorts with liners or explore our full line of men's mountain bike shorts for every kind of riding setup.

Reviews
Pearl Izumi never fails to deliver
"Per usual I love these shorts. I have a pair of their gravel bibs and Pro Road bibs and love them. I was really intrigued by this short as I am primarily a mtn bike that like to have a high end chamois for long rides etc. Pearl deliver perfectly for me as the venting is nice especially on hot days under baggies versus my shorts that are not purpose built for under baggies."
Good quality bib
"Good quality bib"
love the extra pockets
"Super comfortable and the extra pockets are great"
This is great
"Ive been through a few options that really from other sources that didn’t really work out, so I am thrilled to have found these! They’re perfect for me, and light weight for summer…."
Great bibs! Breathe really well
"Great bibs! Breathe really well and the chamois is very conformable from gravel to mtb’s! Only a 4 star due to the sizing being off. I generally wear an XL and I’m not a small person. Every ride it’s getting more comfortable but they definitely run small."
awesome fit
"works great. on hot days its not even a thought"
Incredibly comfortable
"As advertised. Comfortable, well made and breathable"
Too small
"These liners are too small even though I have been wearing your brand for years. I can’t return them since it was a final sale."
Like wearing a wetsuit and a diaper
"Leg size is very tight for waist. Stuck with those in a bikepacking trip in thailand. Most expensive and worst bike short ever own. Stitches rub and cut circulation. Still don’t get the bib thing, maybe good for oversize cyclist woth small leg, or pregnant lady!?"
Good Bibs That Can Improve
"These bib liners are pretty good but not perfect. The chamois is high quality and comfortable. The overall quality is good and they've held up well. Two complaints; 1. They run small compared to other Pearl Izumi bottoms, I am a medium in most shorts but was a large in the older bib liners from PI, in this model the large barely fits me and is pretty snug. 2. As others have mentioned, the waist comes up way too high and is not stretchy enough to make nature breaks very easy or comfortable."
