Whether it's race day or you're on the party lap train, clear vision can make or break the day. The race-inspired Smith Rhythm Mountain Bike Goggles set you up for maximum clarity and a wide field of view in any conditions. When it's wet and muddy, the roll-off compatible design lets you maintain full speed ahead. When the sun shines bright, ChromaPop(TM) makes sure every root, rut, and landing comes through loud and clear. Low-profile outriggers make sure they fit comfortably around a full face helmet. A removable microscreen for additional dirt and debris protection as well as compatible roll-offs are sold separately.
