Once you've been struck with the cycling bug, it doesn't take more than one ride in bibs to figure out why they're so popular. Not only do they provide the necessary comfort and support of quality cycling shorts, but bibs like the Louis Garneau Signature Optimum also stay in place without a pinching waist band. The lowers are constructed with eight panels of Louis Garneau's Signature Optimum fabric. This material's flexible, yet supportive stretch knit is composed of a nylonspandex blend. Essentially, the highly elastic properties of the fabric wrap your muscles in place, providing you with the proper support that, in turn, leads to a little less fatigue. The fabric is also lightweight and highly breathable, which lends itself to transferring moisture away from the skin, keeping you comfortable and dry. And, in addition to this, its anatomically shaped fabric panels are joined with flatlock seams in order to eliminate irritation and reduce chafing throughout the construction. Additionally, Garneau's compressive Powerband leg cuffs keep the leg panels firmly in place without restricting circulation. For further comfort, Louis Garneau incorporated its Silvercool3 chamois into the Optimum shorts. This two way stretch insert conforms to your body and is composed of multi thickness, high density foam for a precise, targeted support. The antibacterial Coolmax top sheet wraps the chamois, so you'll also stay cool and fresh for the long haul. For safety, Garneau has placed back and bottom reflective accents to increase your visibility to motorists in low light conditions. The Louis Garneau Signature Optimum Bib Shorts are available in five sizes from Small to XX Large and in the color Black.
