Fernflow Liner Bib Shorts+ Mens
These airy, padded liner bib shorts were designed to prevent overheating, provide comfort, and offer storage options while worn under your favorite MTB or gravel shorts.
We wanted to create liner bib shorts that meet the demands of long trail rides. Open mesh legs allow for increased airflow and enhanced moisture control to avoid overheating. We’ve also added multiple pockets on the bibs, to stow your packable protection and essentials for all-day exploration.
