A lot of exciting changes were made to the this new generation of the Trek Blaze helmet. Blaze now features an improved WaveCel liner that is lighter and cooler than its predecessor, thanks to larger cells and an optimized use of material, and still provides the same level of protection. The helmet also features more coverage - specifically removable 3/4 ear protection. This removable coverage provides a ton of flexibility, allowing you to choose the best "helmet" for the day. A magnetic breakaway, 3-position visor and a goggle optimized design round out the new creature comforts featured in this great helmet.
