The Giro Switchblade MIPS is a serious, ATSM DH-certified helmet, with a removable chin-bar. This helmet is a great choice for the rider who doesn't plan on wearing this lid for a substantial amount of pedaling due to limited breathability over the ears and high-cheek zone. When charging downhill with the chin-bar removed, the extra coverage over the ears and the high-cheek zone is reassuring and confidence-inspiring. This is our favorite option for aggressive riding but isn't great as an only helmet like the Bell Super DH. At $250, the Switchblade MIPS is a solid value as you are essentially buying two helmets in one.

Our Analysis and Test Results
The Switchblade is a reasonably comfortable helmet in both full face and trail mode.
Testers found this helmet to offer a great feel over the ears. While some DH helmets tend to squeeze your ears, the Switchblade is spacious. Hearing remains impressive and it doesn't sound muffled. The retention system on the back of the head sits at a nice point on the back of the head. It sits at a nice point on the occipital and really feels secure.
No matter how hard you crank the retention dial, there are no pressure points. Our only complaint is that the fit on the very top of the head is a little funky. We wouldn't call it uncomfortable or painful, but it would have been nice to have a slightly wider space at the crown of the head.
The visor is secured by two bolts. One bolt near each temple. The visor is pretty sturdy when you attempt to rock it side to side with your hands. Adjustments to the position are made by hand without loosening up any bolts. Simply pull the visor up and down into one of the three positions. There are three indexed stop points to choose from.
The visor works really well in full-face mode and serves its purpose. In the half-helmet mode, the size of the visor can be problematic. If the visor is in the lowest position, your visibility is seriously limited on mild terrain. On steeper trails, this issue is far less problematic as your looking further down the hill. In the middle visor position the issue is less noticeable and in the high visor position, it is nonexistent. That said, the helmet looks a little goofy with the visor pointed into the sky.
A second visor is included in the box. The additional one comes with a camera mount.
Our medium Switchblade MIPS hit the scales at 34.6-ounces with the chin bar attached. With the chin bar removed, the helmet weighs 24.2-grams.
The Switchblade is the heavier of the two convertible helmets we tested. That said, it is the third lightest full face helmet in the test.
The Switchblade offers impressive ventilation in both settings.
In the half-shell mode, the ventilation is mediocre. Obviously, you can breathe far better than you would with any of the non-convertible helmets. The way the shell extends over the ears and high-cheek zone limits airflow. This issue simply comes with the territory of the extra coverage. When motoring down the trail, the airflow is impressive. Plenty of air gets through when you are carrying a head of steam. Still, the Super DH is a far better choice when if you care about airflow in the trail mode.
In the full-face setting, the ventilation is impressive. The lack of fabric inside of the helmet near the ears definitely helps keep your head cool.
The Switchblade is outfitted with the Multi-directional Impact Protection System (MIPS) system. The MIPS is a layer of material underneath the pads but on top of the foam of the helmet. In the event of an angled impact, this layer moves slightly and reduces rotational the rotational forces that reach the brain. This technology has become more and more prevalent in recent years.
The Switchblade is ATSM DH 1952, CPSC, and EN1708 certified. This DH certification applies for when the helmet is in full face or half-shell modes.
Throughout our test period, we did see anything that would concern us about the durability of this helmet. Removing and installing the chin bar takes a little getting used to. We recommend being very careful not to force the mechanism when reattaching the chin bar. We could foresee some problems developing by improper install/removal.
The Switchblade MIPS uses a classic D-ring system. This tried and true method feels secure although it can be a little difficult with gloves on. When you are ripping park laps, it can be a little clunky clipping and unclipping this before and after every run. That said, you never doubt the security of the closure. It feels like there is essentially no risk of the helmet is going to come off in the event of a big crash.
The Switchblade MIPS is best served as a second helmet for the aggressive enduro rider. This does not make a great single helmet due to the not-so-excellent ventilation in the half helmet mode. Instead, this lid is best reserved for bike park days or shuttle laps where you need a helmet to do a just little bit of climbing.
Riders seeking to simply rip park laps should look into one of the regular full face helmets like the award-winning Fox Racing Rampage Pro Carbon MIPS.
At $250, the Switchblade MIPS is a solid value. This helmet offers MIPS technology and the convertible function does its job very well. If you are looking for a one-helmet solution, we recommend checking out the Bell Super DH which is a much better trail helmet that breathes very well.
The Switchblade MIPS is a convertible mountain bike helmet that gets the job done. This helmet is best used as a second helmet alongside your regular trail helmet. With the shell of the helmet covering your ears in trail mode, this isn't a great choice for long climbs or trail rides. Instead, the Switchblade is a suitable choice for shuttle laps where you still need to pedal a good bit. The extra coverage around the ears is reassuring if you decide to descend in half-helmet mode.
