Fit: The anon fit was pretty comfortable, I found the inside padding nice to wear even with goggles and a balaclava underneath. I took off the ear flaps almost instantly just because I wear my goggles under my helmet as my preference. One nice thing I noticed is the back of the helmet seems to fit lower than my previous helmet (POC bug), which helps keep out a bit more wind from the ba of my head. Obviously it fits well with anon goggles but it has a pretty standard front brim, which most likely fits with a wind variety of goggles. Most importantly, the helmet is equipped with the "boa" fit system, which is nice when swapping out goggles or needing to change the size to adjust for a beanie underneath. Anon also put a new style clip on the helmet strap, "Fidlock" a brand that specializes in making hassle free buckles. It seems insignificant, but I actually noticed a large convince difference between the Fidlock system and a traditional buckle. Even with my gloves on it was easy to clip both in and out.
Vents: Equipped with top and front small vents, nice for the slightly warmer days. In the vents, they introduced a system that brings the cold air in from the front of the helmet, and directs it through the helmet, and pulls moisture and unwanted heat out through the back of the helmet. (this helps a lot with preventing goggles from fogging up.)
I definitely enjoyed the comfort of the helmet, and would recommend it for its comfortable fit and safety.
Anon's Nelson helmet is a stellar entry into the park helmet market. Most park helmets I have seen tend to be on the cheaper side, and are generally very light on features. The Nelson bucks this trend in park-style helmets and has included a number of more premium features.
My helmet is sized as an XL, and is slightly large on me. With a beanie on underneath it fits perfectly, leaving plenty of room to comfortably wear my goggles under the helmet. The helmet features a Boa system, with a ratchet adjustment knob in the rear which offers excellent customization to your head for one of the best fits I have had with a helmet in quite some time. Possibly my favorite feature of the helmet however, is the ability open or close the top vents. Most park helmets either have no vents, leading to frequent overheating, or vents that are always open, leading to being too cold on the really frigid days. Adjustable vents are a must have for me. My only complaint in this department is that when the vents are open, and you are moving at high speed they tend to whistle. While not a huge issue, it is quite annoying to be cruising down the mountain and suddenly have your head howling. I feel a small redesign in vent shape could eliminate most of this problem.
The helmet also features a new buckle system. They call it Fidlock. It is a hybrid magnet and clip system, that is supposedly easier to operate than traditional buckles. The two pieces lock together in the opposite direction from a normal buckle. It is definitely very easy to undo, however I often find myself struggling to buckle it. This is probably because it is such a radical change from the traditional buckles I have used for years. As a side note, I find that the chin strap pad often ends up up-side-down on the strap. It is a minor annoyance, but worth noting.
The helmet can accept speakers in the ear pads, and installation of my Skullcandy (Ones made for a Smith helmet) wired speakers was a breeze. Speakers sit up against your ears, so you can hear your beats loud and clear.
Goggles tended to stay on the helmet quite well when worn in the traditional, over the helmet style. The slight brim makes an excellent catch for goggles when you want to put them up but not have them dangling about behind your head. The strap clip at the rear of the helmet however, is quite difficult to get your goggle strap into.
Overall, I really do enjoy this helmet. It has replaced my Smith Holt that I was previously using as my daily use helmet, and I do not see my self going back anytime soon.
