HJC helmets comparative: FG-17 vs IS-17

HJC offers us two different mid-class helmets that share the same base but with different concepts. Both helmets are just below the most sportive helmet range, the RPHA, so the FG-17 and the IS-17 are two options to keep in mind thanks to tthem being great value for money.

Shell

Despite both helmets sharing a same basic design, we find some differences in the external details of the shell. The main reason is that the IS-17 has a design adapted for integrating the solar visor into its internal structure, while the FG-17 does not have this visor, giving it a more sporty feeling.

The shell of the FG-17 is made with an advanced compound of fiberglass, while the IS-17 is made with polycarbonate. Due to this, and the sun visor of the IS-17, we find that the weight of both helmets varies a bit. The FG-17 weights 1,400 grams and the IS-17 weights 1,600 grams approximately.

The design of both helmets is clean, especially the FG-17, that seeks better aerodynamic efficiency, and has a rear spoiler. On the IS-17, we will find a design with more elegant lines. The helmets have three different shell sizes to adapt to all the sizes on the market (XS-S-M-L-XL).

Ventilation

The air ducts on the inside of the shell are different on the IS and FG helmets. The main reason is that the IS-17 has the sun visor inside the shell, so the internal EPS has been modified.

On the FG we find three air inlets: one on the chin and two located on the shell, all of them with on-off mechanisms. All very easy to use even with winter gloves on. The air circulates through the air ducts to the rear area, reaching the exit situated on the spoiler. This air extractor provokes a Venturi effect on that area, for optimal aerodynamics of the helmet.

On the IS we find an air entrance located on the chin, with an "on-off" mechanism and another air entrance on the shell, with three different positions. In contrast to the FG, the IS includes small air inlets on the visor that optimises the helmet's ventilation and affords the IS-17 a better mark on this subject.

Visor

The visors of both helmets are exactly the same, so they share sporty and touring features that benefit both versions. The visor includes the Pinlock 100% Max Vision, the Pinlock's most effective anti-fog visor, UV protection, anti-scratch treatment and the RapidFire system, which allows us to easily remove the visor without tool. We also find that the visors' closing system via a button on the FG-17, a typical feature on a sporty helmet, is also included on the IS-17.

Both helmets have chin guard, nose protector and a rubber area between the visor and the shell, for a better isulation.

Obviously, the main difference between both helmets is the sun visor of the IS-17. To use it, we will have to press a flange with a spring with two positions which is placed on the upper shell of the helmet. There is also a button that will allow us to remove the sun visor quickly. This is useful in sudden situations of lack of light, such as entering a tunnel.

Interiors and other details

The padding of the helmets is different. On the one hand, the FG-17 incorporates the SilverCool system, where the pads have an anti-bacterial and anti-humidity system. At first glance, we realise that we are before sportive and very breathable padding. The interiors are removable and washable.

On the other hand, the IS-17 incorporates the SuperCool system, that has an anti-bacterial treatment but its padding has optimal feel with less microperforations, designed for a prolonged use.

The closure system of both helmets show us the segment of each one: while the FG-17 has a double ring closure system for a sporty use, the IS-17 has a micrometric one, easier to open and close but not allowed on the race track. Both helmets are prepared for intercom systems.

The helmets use different closure systems: the FG-17 has a double D closure while the IS-17 use the micrometric one.

Conclusions

HJC offers two mid-class helmets where their quality-price relation is very competitive. Both include features to optimise comfort and versatility and both are stuffed with sporty and touring details. Their price on the market is very similar and it will vary depending on their graphics. At the end, our choice will depend on our preferences: sport-touring segment (FG-17) or versatility and comfort for daily use (IS-17).
