Men's Mesh Bib Liner

The Mesh Bib Liner takes breathability to the maximum while providing a full-featured high-density chamois for all-day riding comfort and support. Using a highly elastic net mesh and our proven bib fit, straps, and leg grippers, we created an incredibly comfortable, light, and airy liner. The Mesh Bib Liner features the same top-quality dual-density chamois found in our Signature Bib Shorts. Two mesh cargo pockets on the outside of each leg add storage space with easy access.

Materials & Care

Fabric Content

75% Polyamide,25% Elastane

Made in IT

Caring for your cycling gear properly will extend its life and maintain its performance, fit and quality. Its important to consider these instructions carefully. While we stand behind the quality of our apparel, not adhering to these instructions will void our warranty against manufacturing & defects. 

We strongly recommend washing your new gear before wearing it. Youll find that your apparel will soften, and fit & comfort will improve after washing - especially with bibs & shorts. 

Machine wash cool, 86F (30C) with like colors: Cooler temps maintain better longevity for your apparel. Like colors, especially lights, will remain more vibrant when washed with like colors. 

Use mild detergent. Do not bleach or dry clean: Strong detergents & bleach can break down the fibers and elastane in the garment, dramatically reducing its life. 

Close all fastenings: this goes also for other garments mixed in with your cycling apparel. Velcro closures or clasps can catch on stitching or trim and damage your garments. 

Lay flat to dry. Do not tumble dry: Do not put your cycling apparel in the dryer. Even on low heat. Dont do it. Heat can damage fabric, elastic and heat transfer logos very easily. Lycra (Elastane) is used throughout our garments to provide compression and support and is susceptible to damage from heat and can irreparably damage your apparel.

Still my favorite bibs

The Velocio Bib Liner is still my absolute favorite pair of bibs. I bought my first pair three years ago and put them through ****. Had it not been for them being stolen (I know, gross, right?) I would still be wearing them. But I loved them enough that I bought a replacement pair without hesitation and the new ones are just as good as the pair I had for three years. The only thing that confuses me is why Velocio chose to put pocket on bib liners. It seems to me like they'd be better off putting these on their entry level bibs and leaving them off the bib liners. I've never once used the pockets on these and can't see how I ever would consider doing so since I have the trail shorts on over top of them.

Best liners I have ever owned

Not hyperbole. These are the best bib liners I have ever owned. They are light but don't feel cheap. The chamois is great for pedaling. Other bib liners I have owned were light and felt good under shorts, but the chamois was garbage for long days in the saddle. I would wear this liner for any ride, but they are perfect for long MTB rides that require a lot of pedaling where you still want to wear a baggy short on top

Great chamois, ultra thin material breathes exceptionally well, and the straps disappear off your back. They're perfect.
