If you're wondering why you'd want to pony up the extra cash to invest in ZOIC's Ether Premium Shorts over the brand's other, humbler Ether versions, we understand your concern. After all, we're discussing mountain biking kit, not impeccably tailored custom suits. Though you'll enjoy the same DuraFlex stretch fabric and wealth of pockets in the Ether Premium as you would in its less pricey sibling, the IPL Premium Liner represents the main difference in pedigree between the Premium and regular versions of the Ether. Complete with a built in Cytech Elastic Interface Speed Plus Chamois, the IPL Premium Liner is constructed with six panels of odor resistant, breathable fabric that provide a wrap like fit around your muscles as you ride. ZOIC uses reverse stitching when linking the panels together, which places the seaming away from your skin to lessen the likelihood of chafing, and it lines the lightweight design with the stretchy, plush cushioning of the Elastic Interface chamois to give you long term comfort on the trails. Back on the shorts' outer shell, a gusseted design helps you maintain freedom of movement while you move along on the trail, and six well placed pockets give you plenty of space to store ride nutrition and other essentials.
