At the moment, we're big fans of what Specialized is doing. These bib liners have all the ingredients of a solid short: mesh fabric to keep you cool, a well-designed and comfortable chamois and a fold-over leg cuff so things stay in place. But what separates these liners from others is the SWAT (storage, water, air, tools) design, which incorporates large storage pockets into the back of the bibs so you can get rid of cumbersome hydration packs. And because the position of the pockets is on the lower back, it doesn't jostle around while you're on the trail. This comfortable, efficient storage solution gets an A+ from us.
