Comfortable helmet, hard to adjust.

I’m just getting back into biking. Recently traded out my old Stumpjumper for a comfort bike. I needed a new helmet so purchased 4 different helmets online during the last sale. Got this one for $112.00. I’m probably going to keep this one. I have two remaining contenders. What I like about this helmet is the fit. The visor is nice and it’s comfortable with my sunglasses. Minus 2 stars for the strap. The buckle is heavy and the straps don’t stay in the position I put them in. The ventilation is outstanding on this helmet.
