Oakley's performance gear is unparalleled — which you'd understand if you ever tried the brand's premium shades. Now's the time — a ton of sunglasses, including the speedy Flak Beta Rectangular Sunglasses, are upwards of 50% off during Amazon Prime Day.

Happy Prime Day, fellas. For those of you unaware, Amazon kicks off its sale bonanza today, which includes literal thousands of deals on gear, garb and gifts. Top of our shopping list is a pair of Adidas Gazelle's, cousin to the Samba and the perfect retro trainer to rock this summer.

The graphite/black version of the Fitbit Charge 5 fitness tracker is currently $50 off at Amazon. And it's not just useful for exercise — the Charge also tracks stress, recovery, sleep, heart health and more.

The July Window Air Conditioner is nearly unrecognizable as an AC unit. That’s due to its discreet, stylish cover available in a multitude of colors and “premium materials,” along with inconspicuous buttons situated at the top of the unit and a nearly obscured vent.

This uniquely designed neck pillow is the only thing that has helped us sleep while in flight. Now 25% off on Amazon, the TRTL travel neck pillow is lightweight, easily fits in a carry-on bag and accommodates all different sleep preferences.

Right now you can save up to 40% off at Allbirds, makers of those extremely comfortable and colorful slip-ons. Note: Sizes and colors widely vary.

As much as we hate to admit it, Prime Day kind of rules. Where else can you get a two-pack of cooling, sweat-wicking Hanes X-Temp Tank Tops — the cornerstone of any solid summer outfit — for just 11 bucks? Find us a better deal...or, just grab a pack for yourself in a variety of basic colors.
