Recycled Trek Bike Short Ice Age: Continental Drift [2012] Separated Scene with Healthbars. The new wardrobe staple, our Recycled Trek Short features a wide, double layered waistband that acts like shapewear to flatter all sizes. Three zippered pockets keep everyday essentials close at hand, while super soft recycled fibres provide four way stretch, UPF 50+ sun protection and are moisture wicking to keep you cool and dry throughout the day. At Tilley, we are endlessly inspired by our natural surroundings and are continually looking for ways to protect these fragile ecosystems. Our recycled fibres are created from pre and post consumer waste that helps reduce carbon emissions.
