The Bolle X-9 are sturdy goggles for snow skiing, winter biking, and other activities. They have great optical clarity and feel comfortable on the face thanks to the adjustable strap.
At 3.9 x 4.6 x 8 inches, these goggles will cover your face from the forehead to the cheekbones. They will suit medium and large but not petite faces. The weight is 0.5 pounds so they are lightweight.
The X-9 is one of the few models from Bolle with the OTH (over the helmet) fit. The same feature is also present in the Bolle Carve but, unlike the X-9, it can't offer an OTG feature. The OTG means that these goggles fit over prescription glasses. The special indents on the frame ensure that you won't feel excessive pressure on your face while wearing the glasses underneath. For this reason, they are bigger than average goggles. So, in order to get clear testing results for this Bolle X-9 OTG goggle review, I tried to put them on without my eyeglasses and found the X-9 a bit bulky on my face.
The strap is adjustable. It allows for simple regulation and helps keep the goggles in place during fast rides and jumps. Three layers of face foam are covered with a soft polar fleece providing comfort for your skin.
The Bolle X-9 OTG goggle is designed to fit most modern helmets. There is a rubber lining on the strap that provides a better grip on the helmet's surface.
The double-lens construction serves as a thermal barrier protecting you from cool temperatures and providing a better seal, so the snow and raindrops won't get inside. The lenses are generally very clear and do a great job in protecting your eyes from the snow’s brightness. They also easily block all types of UV rays.
Bolle uses its proprietary technology to make their goggles both scratch- and fog-resistant. For this, it utilizes the P80 carbo glass that has the ability to eliminate moisture build-up.
The Flow-Tech venting technology also makes the goggles breathable providing both the anti-fogging and anti-heating effects. Nevertheless, they will fog up a bit if you won't be active for a long time and there won't be enough airflow moving through the vents.
The goggles have some issues but are generally satisfying, so I rate them at 8/10.
My goggles had lenses of a vermilion color. It appears to be good for both sunny and cloudy days. However, when it starts getting darker outside, they lose a bit of their clarity. The black frame isn't flat and protrudes from the lenses (especially in the nose area), but it doesn't interfere with the view.
These goggles have a pretty classic design as for an OTG model and there is nothing fancy about them. This way, I rate the design at 10/10.
The Bolle X-9 ski goggle is a decent basic model for non-demanding riders. It will protect your eyes from heating and provide a fog-free view if you won't stay in one place for a long time and move a lot.
