Bell Influx Bike Helmetis rated4.3333out of5by12.
Rated2out of5byfromDon't leave in direct sunlight!It is kind of a problem if it cannot be in direct sunlight...that is when I ride! It loses its structural integrity after that and cannot be safely used again without a replacement...poor choice of materials.

Rated5out of5byfromWould buy this product againAlways wear a helmet, from now on. Helmet fit with trial fitting, but when wind gets under it, flopping around. I think, a size too big.

Rated5out of5byfromIdeal Helmet!~I really like this helmet. I bought it to replace one that was with me in an accident and this one performs far better than that one.

Rated5out of5byfromExcellent ValueFortunately haven't "tested" it's durability yet, but it seems solid, is easily adjustable for a perfect fit, and happens to look great with my bike. I guess this is a 'budget' helmet, but it suits my needs provides ventilation in the Texas heat and is very comfortable.

Rated5out of5byfromNice look and lighweightI've had this helmet for a couple of weeks and it is a good fit for my daily 30-mile commute. The vents help considerably in this Texas summer heat. I have noticed the straps are a little stiff but I expect they will limber up with use.

Rated4out of5byfromGreat helmetBought this helmet over the internet. Since I was not able to try the helmet on in the store, I selected the size recommended by Bell based upon my head circumference. The fit was spot on after making slight adjustments to the various straps. My only real complaint is that I have had a little difficulty with the strap on the right side of the helmet pinching my ear. I'm hoping that I can eliminate that problem with a few more tweaks to that strap, but we shall see. Otherwise, I absolutely love the helmet. It provides great air flow which is extremely important with the hot Texas summers. The visor is also a great feature even if you wear sunglasses. Overall I'm very satisfied with this purchase and would recommend to others.
