Gearing up for rock climbing, caving, or industrial work where head protection is a must? The Tontron CH02 is a reliable, certified helmet that gets the job done. Its outer shell is made from tough ABS plastic, and the inner liner is high-density EPS foam – a classic combo designed to absorb and dissipate impact energy, meeting the strict CE EN12492 safety standard for climbing helmets. It has 6 ventilation holes to keep you cool (designed sideways to help keep small debris out). The adjustable headband at the back ensures a secure and comfortable fit for most adults (available in Small 19.3-21.6\ and Large 21.6-23.6\). Built-in clips on the sides make it super easy to attach any standard headlamp for hands-free lighting in dark caves or early morning climbs. It's lightweight (about 370g) and versatile enough for climbing gyms, outdoor routes, spelunking adventures, or even as a general work helmet. Safety first – this helmet provides essential protection without breaking the bank.
