Figure 3.1: LS2 Helmets Size Chart. This chart provides head circumference measurements corresponding to various helmet sizes (XXS to XXL).

LS2 Helmet Size Chart

XS	53 - 54
S	55 - 56

3.2. Proper Helmet Fit Test

Place the helmet on your head, ensuring it sits level and covers your forehead.
Fasten the chin strap securely using the quick-release ratchet system. The strap should be snug but not uncomfortably tight.
With the strap fastened, try to move the helmet from side to side and front to back. Your skin should move with the helmet, indicating a snug fit. The helmet should not slide freely.
Check for pressure points. While a snug fit is necessary, there should be no excessive pressure on any part of your head.

4. Operating Instructions

4.1. Using the Quick-Release Ratchet System

The SR2S quick-release ratchet system allows for easy and secure fastening of the chin strap.

To Fasten: Insert the notched end of the strap into the buckle until it clicks securely. Adjust the strap length for a snug fit.
To Release: Pull the red tab on the buckle (marked "PULL") to disengage the ratchet mechanism and release the strap.

6. Troubleshooting

Common Issues and Solutions
