Keep Your Cool This Summer With the Sony Reon Pocket Wearable Air-Conditioner

If it seems like the summers just keep getting hotter, you’re not imagining things. Last year was the third-warmest on record, and the summer of 2019 was the hottest since we started recording such things more than 140 years ago. The right fabrics can, of course, help keep you cool. But, sometimes, that’s not enough. That’s why Sony is using its considerable ingenuity to throw technology at the problem with the new Reon pocket air conditioner.

The Reon Pocket is an ultra-portable “wearable air conditioner.” The sleek, all-white device is smaller than a deck of cards, so it’s designed to be almost invisible. The wearer slides it into a special pocket sewn near the top rear of a corresponding lightweight Sony undershirt. Through a bit of clever science, it promises to drop the wearer’s body surface temperature up to 23 degrees Fahrenheit in hot weather. In winter, it can act as a miniature heater by raising the surface temperature as much as 14 degrees Fahrenheit.

A companion smartphone app (for Android and iOS) controls the Reon via Bluetooth. Users can manually set their preferred temperature, or switch to auto to let the device handle the heating or cooling for them. In auto mode, Reon reads the wearer’s activity level through built-in motion sensors, then dials the power up or down accordingly. It charges in around two hours through a standard USB-C plug and lasts up to three hours.

Reon might sound like a silly “As Seen on TV” novelty, but it’s based on sound, 19th-century science. It uses the Peltier effect to raise the temperature on one side of the device while lowering it on the other. When pressed directly against the skin with the built-in silicone pad, it can actually regulate body surface temperature. It also works as a handheld device, though not nearly as effectively.

The Reon is primarily available through the Sony Japan online store for around $120 (¥13,000). Add another $20 for the matching V-neck shirt (available in small, medium, and large). So far, however, it’s been so popular that Sony is having a hard time keeping it in stock.

If a fancy wearable gadget isn’t enough, check out our roundup of the best portable air conditioners to keep you cool this summer.

3 things I wish I knew before buying my first mountain bike
3 considerations for buying a mountain bike
Opening and beginning to build the Canyon Spectral CF 8

I bought my first mountain bike in the early 2000s. Back then, there weren’t as many mountain bike options, and they certainly were not nearly as expensive. I worked an entire summer and spent the entire $750 on a new mountain bike.

Fast forward to 2021, and I was getting back into the sport after a long hiatus. Mountain bikes had changed significantly—for the better—and I was quickly playing catch-up. One thing that had certainly changed in the nearly two decades since I purchased my first mountain bike was the price.

Best 4th of July grill deals: Save on Traeger, Blackstone and more
An opened Classic Joe III with food cooking, from Kamado Joe.

Are you ready for the full intensity of the summer ahead? We can already predict that this summer will be hotter than usual, but that also means that it will likely feel longer. As a result, there are going to be more evenings and, later, great autumn days to be outside and spend time with our families. At least, that's what we hope. Taking advantage of 4th of July grill deals, then, will be an excellent way to celebrate. Whether you're looking for traditional grills and smokers, charcoal grills, or even gas grills, there are great deals to take advantage of right now. The following are our favorite for this season.
Coleman 4-in-1 Portable Propane Camping Stove — $70, was $125

This one is a bit tinier than the rest, with only a 100 square inch cooking surface, but its got a price and versatility level to match. With a tripod base and a small 14.4 x 10.5 x 13.9 inch body, you can easily take this will you and set it up on any bench. It has versatile cooking modes that include a grill, grill, wok, and even stove. It's recommend for groups up to four, but with a bit of raw veg and good drinks, we're sure you have the ingenuity to stretch the meal to five or six. This is not an advanced grill, but it doesn't have to be if you're looking to be on the go.

Home Depot 4th of July Sale 2024: Best home and garden deals
The Magic Chef 27-lbs Countertop Ice Maker next to iced drinks.

The 4th of July marks America's Independence. For adults, who haven't been firmly out of school for several weeks by the approach of the holiday, it also marks a sort of in-your-face realization that summer is truly and actually here. And for manufacturers and retailers, it marks one of the best times to attract customers to buy things for the outdoors. That could mean the best Blackstone cooker, a different 4th of July grill deal, or even an outdoor Jackery solar power generator. Yet it could also be the time to finally get one of the best cordless drills and start your wireless, battery-powered power tool collection off to a good start. Whatever your plans this summer, you should know that Home Depot is having a pretty massive sale to celebrate. Here are the home and garden deals that you should be on the lookout for to get your summer moving.
Magic Chef 27 lbs. Portable Countertop Ice Maker — $99, was $159

It's summer, and if you haven't used your refrigerator's ice maker in awhile, you may notice that it's pretty yucky smelling at the start of the season, slow, and extremely non-portable. This stainless steel ice maker goes with you and starts making ice fast, very much unlike sticking a try in the freezer. Just put some water into it and within the next seven minutes you'll have your first nine cubes. Not 27-pounds itself (that refers to the weight of ice it could, theoretically, make in a day with constant use) this little ice maker is a mere 12.1 x 9.5 x 14.1 inches (HWD), making it perfect for small spaces.
