The FS260s had the pleasure of being my lone pair of shorts on a week-long tour. The field sensor material fits snugly and supports leg muscles, while the broad waistband is super comfortable as it's non-elasticated. This makes bending forward on the bike less restrictive.
Cut is high waisted and can be pulled up high in the back, though it dips at the front. The eight-panel construction gives a contoured fit and the seams are hardly noticeable. Like many of the top shorts, they feature a women's-specific stretch pad - it's wide, moderately padded, stays comfortably dry and has an antibacterial treatment. My only gripe is that without a 'tight' waistband the shorts tended to sag by the end of a long day and caused some friction. Silicone leg grippers hold the legs in place.
