The Tonic helmet offers protection, style and comfort for riders who are just getting into cycling. The inconspicuous design of the helmet makes sure it is at home wherever you take it. An in-mold construction is used to keep the weight down while 28 vents make sure you are always cool and comfortable while riding. A dial at the back of the helmet controls a basket that secures a large part of the back of the head. A quick turn of the TS+ dial assures a snug yet comfortable fit that keeps the helmet firmly in place. Adjust it on the fly and start your cycling adventures.
We are a Seattle, WA based outdoor gear store with a mission to make climbing, backpacking, skiing & mountaineering accessible and enjoyable for everyone.
