Good helmet, great price. Had one before got damaged and needed to be replaced. Like a half helmet because it is cooler to wear in hot weather.

Nice product. Quality construction. Sits a little too low over my ears and thus pushes the top of my ears down and out. Otherwise seems to fit my head ok. I do enjoy the freedom that the half helmet offers vs a full face model when the weather is warmer.

HJC CS-2N Helmet Review

The HELMET was correctly suited me. The VEGA MERGE BOOTS fitted me so nicely and very comfortable to use. I like it. The MENS MV120 BULLETPROOF VEST is beautiful and the quality of the leather is absolutely great. However, i wrongly made the correct size, its a bit big for me.
I am planning to exchange for the size ONLY to SMALL (S) SIZE, as i originally ordered the LARGE (L) size.

Helmet is good just as I expected. Tried one on at the local motorcycle shop but was $20 cheaper to order. The part I was impressed with was the shipping time ...super fast !!!

This helmet is exactly what I wanted. I have been using an HJC helmet for a few years but mine was "bulkier" than this and often made my neck sore after riding. This version is perfectly balanced and easy on my neck muscles. The zip out liner is perfect for those chilly days. Great value even with shipping compared to prices at my local shop. HIGHLY recommend this helemet.

Good product... GREAT Customer Service!!

by - verified purchaser
My head measured a M,( I currently wear an HJC M). This helmet arrived and wasn't even close! I went to a retailer for sizing & discovered this model fit in XL! I contacted Jafrum customer service and was more than pleased... I received the return form in my e-mail while I was still on the phone. Following instructions, I received a replacement helmet of the correct size in less than a week! Helmet seems of good quality & customer service of Jafrum will keep me a customer!!!

Great Helmet

by - verified purchaser
I bought 2 of these one for myself and one for my Wife. I measured 24", have an oval shaped head and got the XL. It was fairly snug but has broken in nicely and is comfortable now. My wife's is a small and she has a rounder shaped head at 21 3/4" it seems to me like it could be a tad loose but she says its not, and its comfortable. The zip out neck curtain is nice and well made, so is the rest of the helmet. I only wish the liner was removable too. None the less a great quality helmet for the price.

I Like It

by - verified purchaser
Bought the helmet to use when a modular helmet is 'too much'. It fits my head well. The sizing chart is dead on. It seems a bit snug now, but I'm sure it will fit better when it's broken in some more. A previous reviewer said it squashed his ears down. I noticed this as well. But after only a few rides, it seemed to subside to almost nothing. I meant to order a half helmet with a sun shield, but this doesn't have one. On the up side, it holds my sunglasses on securely and doesn't press on them. My modular seemed to have distorted my shades as to make them fairly useless. So far, I'm liking this lid a lot. Oh, plus it has the zip in/out neck protector for the cooler days in the fall. I would not hesitate to buy another of this model or the same type from HJC, but with a shield.
