The Helmet

Type
Biking helmets are basically of two types, hard shell and soft shell. The principle difference is that a Hard-shell helmets have thin plastic surface, while soft-shell helmets have only a soft foam surface. We prefer hard shell helmets because when a hard shelled helmet hits rough ground it skids rather than catching on the ground, this may save the neck in a worst possible scenario.
A helmet which has already suffered a crash should not be reused. An impact may damage a helmet's foam, and it may not protect you well enough in the future. naturebeyond supplies hard shell helmets for its biking tours. We suggest bringing personal helmets if available since our helmets are only of one size.

What to look for in a helmet
Fit:You must have a good fit. A good fit means that if your head is hit more than once, the helmet will stay in place. Most brands of adult helmets come in two or three sizes, and you can make them fit even better by adjusting the straps. Don’t wear helmet tilted back on head, it won't protect your head in a frontal impact.

How to Check For A Good Fit
1. The helmet should sit level on your head.
2. As you move your head after fastening the helmet, the helmet should not move around on your head
3. With the straps tight, you shouldn’t be able to remove the helmet.

Ventilation: A helmet's ventilation depends on front-to-back flow. Good air flow comes from long, wide air vents, and air passages (otherwise known as troughs) between the vents.
