Wearing sunglasses with full-coverage helmets that drop behind the ears can be tricky. And, while the new Giant Rail does provide a good deal of protection toward the back of the head, its shape makes wearing sunglasses far easier—a detail that's hard to appreciate until you find out your favorite shades don't work well with your new helmet.
With large vents and deep internal channels that allow air to move over the head and out of the helmet, the Rail is sure to keep you cool while out on the trail. Our one complaint is the helmet's visor, which gets in the way with some helmet mounts for lights and cameras due to its inability to be raised or lowered. Overall, though, the Rail is a race-ready helmet at entry-level pricing.
