A perfect-fitting hockey helmet is imperative for maximum safety and performance. Sometimes getting the perfect fit is a simple matter of adjusting the chin strap or chin cup, adding a sweatband liner, or adjusting the helmet using whatever sizing system came with it. Some helmets have a dial on the back to make it bigger or smaller, or side tabs to adjust the fit. Refer to our guides, How to Fit a Hockey Helmet and the Hockey Helmet Buying Guide, for detailed information.
