These shorts and bibs have been design to guarantee all-day comfort during ultra-endurance road and gravel events, when a variety of conditions and terrains will be encountered over extreme distances.

The 12-Hour chamois was co-developed with Elastic Interface® and our development team to create the world's best ultra-endurance pads.

"Pactimo says the Summit Stratos Bibs are designed for 'guaranteed comfort on extreme adventures'. That is a bold statement, but these shorts actually deliver on that promise. They are hands down the most comfortable bib shorts we've tried." - Road.cc
