Troy Lee Designs A1 MIPS – additional safety on the modern classic

The Troy Lee Designs A1 is already a very popular helmet, and is now available in three different styles.

The Drone is the cheapest, with a simple matte finish; then there’s the Reflex series (check our review here), and now the top flight MIPS model for maximum protection.

Look closely and you can see the MIPS liner on the back upper vent.

The Details

Like the A1, the A1 MIPS is available in two versions – the A1 MIPS Drone priced at £139.99, and the A1 MIPS Vertigo priced at £159.99. Both versions are available in several colours – check the range out right here

The same beautiful styling from the regular A1 is present on the A1 MIPS – and there are several striking colours. We love the simplicity of this grey model, but there are some insanely loud models too!

The A1 MIPS Vertigo comes with a storage bag, and features the same high quality aluminium visor screws and retention system as the other models.

There are 8 intake vents, and 8 exhaust vents – which work very well, though there is a large part of the side of the helmet with no vents. This does make the A1 MIPS a touch warmer than other similar helmets – but really does make it feel a lot safer in use.

The MIPS system is attached to the inside of the A1 MIPS shell via rubber mounts that allow the liner to slide.

Inside is the same incredibly comfortable one-piece liner, that can easily be removed and washed (we recommend placing inside a pillow case so it doesn’t snag on other items, and avoid tumble drying to keep it in one piece). Instead of hook and loop fastening direct in to the helmet, the liner attaches to the MIPS system.

MIPS (multi-directional impact protection system) is a sliding cradle that is suspended inside the helmet, which allows the helmet to move slightly around your head. This is to combat the rotation of the skull that can happen if your head strikes the ground at an angle, and grips – rather than slides.

Out on the Trail

The A1 MIPS is incredibly comfortable once you’ve bedded it in – and the extra protection is a nice peace of mind. I like to put my glasses on the rear of helmets for climbing – the MIPS system does make this a little more tricky compared to the regular model though.

One of the things I love so much about the A1, is the incredible fit. It’s the only helmet that fits me perfectly – so I was concerned about the MIPS system, as although thin – still takes up room inside.

Feeling a tiny bit more snug than my usual A1, the A1 MIPS also felt like it sat up on my head a tiny bit more – the first ride left me with two marks on my forehead where the padding would push in to my head. I ended up adjusting the position of the cradle out back to compensate, though as the liner wore in the fit improved and it’s now nearly as comfortable as my usual A1.Troy Lee Designs A1 MIPS Vertigo Helmet

In use it doesn’t feel much different, although I’m sure the venting is hindered very slightly by the MIPS unit inside. The vents are all in the right places on the MIPS unit, but I’m sure the air flow is very slightly restricted – I noticed when running it back to back with my regular A1.

However, the peace of mind offered by the additional protection soon makes you forget about this.


We Say

Though the regular A1 still offers great protection, it’s nice to have the A1 MIPS as an option. 

Whilst there’s no doubt sure the MIPS system is effective in many situations, it particularly appeals to me for urban environments – like commuting. With the types of crash that you are subject to around tarmac and concrete, I see MIPS as a massively valuable addition – and well worth factoring in.

The A1 MIPS takes an excellent helmet, and increases the protection. What’s not to like?
