Overview
The Heatwave MXG-250 is a goggle with a classic shape, a minimalist aesthetic and plenty of tech to ensure it performs well out on the trails. Heatwave has predominantly been focused on sunglasses until this point, but their MXG-250 is the brand’s first foray into goggles.
There are a variety of frame and lens options to choose from. Whether you’re after a subtle look or going for more of a ‘party person’ vibe, they’ve got you covered. At Flow, we’ve had the ‘Stealth Black’ version along with the ‘Icon White’ and ‘Hyrdocraft Aquatic’ colour variants strapped to our helmets to put them to the test.

Key Features
Frame
The Heatwave MXG-250 has quite a classic look to it and it was instantly a feature we really liked. The sharp angles and stealthy asethetic were a crowd favourite at Flow HQ. The goggles feature a smart vent structure under the eyes, either side of the nose piece. This allowed for plenty of airflow and helped to keep the goggles fog-free during testing.


The nosepiece can be a contentious issue with goggles. We’ve ridden goggles before that squeeze your nose to the point that it sounds like you’ve been sucking on helium. Thankfully, that’s not the case with MXG-250s, they’re firm but by no means tight.

The frames are quite thick, compared to other mountain bike specific options out there. This adds to the overall the depth of the goggle but hasn’t caused any intrusion with fit or comfort. The thicker padding makes for a comfortable fit, and we didn’t have any compatibility issues with this on our TLD D4 or Smith Mainline helmets.
The added depth of the goggle can largely be attributed to the thick foam used. It’s extremely comfortable and absorbs sweat well. We’d say this is important in a moto goggle as you may often ride for an extended period of time. In comparison, most mountain bike trails are only a few minutes long and then you remove your goggles for the uplift back to the top. The size may be an issue of style for some, but there is no arguing about the comfort and sweat wicking performance. We should also add that we didn’t find the thicker foam to obstruct our field of vision at all.

Lenses
We were stoked to see two lenses included with MXG-250 goggles. There is a tinted and a clear option included, both with what they describe as “extreme-condition anti-fog coatings”. Certain colour offerings come with a reflective tinted lens as opposed to the standard tint, colour matched to the style of goggles.

The tinted lens worked great in sunny conditions, but doesn’t have the same low light capabilities of lenses like Oakely’s Prizm or Smith’s Chromapop technology.

Available Colours
The MXG-250 goggles come in eight distinct colours, among them the sleek Stealth Black highlighted earlier. The Flow team has also tested the stylish ‘Icon White’ and ‘Hydrocraft Aquatic’ options to add a splash of colour, with the latter including a reflective tinted lens that complements the goggles’ aqua accents.

Flow’s Verdict
The MXG-250 is a goggle with a clean aesthetic as well as plenty of great tech features incorporated into both the frame and lenses. There are 8 colourways to choose from as well as multiple lens options. For Heatwave’s first ever goggle, MXG-250 is a strong contender and we’ve been thoroughly impressed with the fit and comfort.
