Boston is loud in all the right ways.
The hum of the start in Hopkinton. The scream tunnel at Wellesley. The crowds that carry you through Newton when your legs start negotiating. The final turn onto Boylston when the noise somehow gets even louder.
At just 1.7 ounces, the ultra lightweight Unicorn Standard Hyper G Hat is built for moments like that. With laser-cut venting throughout, it pulls heat and sweat out fast so you stay cool from the early downhill miles to the late-race grind.
Fang-style panels give it an aerodynamic feel with barely-there structure, while the built-in sweatband handles the effort when things get serious. Finished with a comfort stretch closure for a secure, bounce-free fit — so the only thing you’re thinking about is the next mile marker.
From the first cheer to the final straightaway.
Light enough to forget. Fast enough for Boston.

"I bought this hat from the HyperG series (assuming there was a difference in sizing), but as a larger headed gentleman I find this barely clinging to the crown of my noggin. I’m gonna wear it regardless because it’s such a sick hat, but if it was just a tad deeper and sat closer to the top of my ears, I’d be the happiest lad this side of the Mississippi. Otherwise lovely product!"
"Crowns on these hats continue be too shallow for men’s heads (I am size 7 1/2). Well made but don’t fit deep enough."
"Love! Im not a runner but play a ton of outdoor pickleball in the hot florida sun. These hats are perfect to keep your head covered and cool! The lightweight material and holes make it perfect for wearing for hours. Highly recommend. In also have a smaller head and the adjustable sizing still works! Awesome hat"
"Super disappointed in this hat. I wear a fitted size 7 1/4-1/2 • and this hat asjusted to the tightest fit… stays flying iff my head while *jogging :/ the only way it stays on my head is literally brim over brows. Not a fan."
"Great fit, easily adjustable. Love the colors."
"Lightweight snd breathable. Love the colors"
"Great vented cap for running. Would like it in additional colors."
"I have both the OG and the HyperG hats and definitely prefer the HyperG in terms of wearability and for runs mainly because of the stretch closure- stays on my head without having to adjust the backstraps every time I wear it. That being said, I wish it came in the same fun designs as the OG hats! Or maybe put a stretch closure on the OGs, or even better a stretch closure and more prints in the women's ponytail hats!!!"
"Perfection!"
"The photos do not do justice fo how vibrant and pretty this hat is!!! Super amazing and perfect for my sweaty head. I always have to remove my hats during my run when I start getting too hot, but this is perfect and breathable. The only thing I would change is adding a top hole with an adjustable button for people who wear their hair and ponytails."
