www.amazon.com, www.amazon.com

Promising review: "Great fan. Used while in Disney over the summer, and it was strong and lasted all day. I really like that it tells you the percentage of the battery, so I could judge how much longer I had to use it while we were out in the heat all day. There were a couple of days I used it all day on various speeds and still had 25% left by the time we got to our room at night. Great battery power. Small enough to carry or wear with the strap around your neck. Strong air flow, and it wasn’t loud. I would buy again." —AWright

Get it from Amazon for $9.99+ (available in nine colors). 

2. Or, a neck fan if you want to go hands-free and enjoy the nice breeze without even lifting a finger. This has three adjustable speeds to choose from, and the LED screen on the side lets you know how much charge you've got left. Plus, reviewers say it's super comfy and lightweight! 

www.amazon.com

Promising review: "We purchased three of these neck fans for a summer trip to Greece. I really like that the fans have a display with the battery charge percent as well at the fan speed setting. There are three speed settings. Recharging was easy with the included cable that plugs into any USB outlet or converter. The fans are lightweight, easy to use, relatively quiet, and comfortable to wear. They kept working for hours while we toured ruins in the hot sun." –Jarrid Z.

www.amazon.com, Amazon

Promising review: "I have been carrying these with me everywhere I go for over a year. It's easy to throw a couple in a pocket or a handful in your bag on the way out the door. They take up virtually no space. Since each individual portion of Purell is completely self-contained, I can keep them in my car during the Arizona summer with no chance of heat expansion or evaporation. Also, a must for travel!

Amazon

Psst — you should definitely "patch test" this on a small area of skin before putting it on to ensure you don't have any reaction! 

Promising review: "I saw this product on TikTok, and I decided to give it a shot since it was only like $20 for 10 wipes (that's 10 weeks, 2.5 months) of no underarm sweat. It worked! I was so happy to finally be able to wear all the shirts I own that are not black!" —Nes172011

www.amazon.com, www.amazon.com

Promising review: "A friend of mine told me about these. Brilliant, I can't believe I lived without them for so long!

www.amazon.com

Promising review: "I used these several times for the past year, traveling for business and leisure. It is always a challenge to find an outlet at the airport since some airports do not offer a charging station. Using those types can also be a security risk. That's why I love using these portable chargers. They are lightweight and fit in my travel handbag or small backpack pocket. The portable chargers take about 30–35 minutes to fully charge if dead. Once charged, they charge fast and hold a charge for many hours." —J

Stay Away is a small business that specializes in pest-removing and repelling products. 

Promising review: "DEET doesn’t work for me, but this does! I’m the person who gets bitten while everyone else is fine. They follow me, and most repellent isn’t very helpful. This worked great! They came near but didn’t bite. The smell isn’t bad either! I didn’t mind it, and my sister has requested some also (she gets bitten even more than I do). I would have preferred a continuous spray nozzle, but I’m very impressed with how well it kept those dang mosquitoes away in Texas! I did sweat a little, and it didn’t change how well it worked." —eve

Get a four-pack from Amazon for $26.99(also available in other packs). 

10. A folding mini hairbrush because the sunshine calls for an all windows down type of drive to the beach or the backyard barbecue with the fam. This won't take up a lot of space in your purse and is great for touching up any knots or tangles in your wind-blown hair.

Promising review: "There’s probably not too much one can say about a traveling hairbrush, but this one is really smartly designed and well-made. Does not take up a lot of room, and the hinge is good quality, so the item stands up to repeated use. It just does not feel flimsy like other travel hairbrushes." —B. H.

www.amazon.com

Promising review: "These lemon GoMacro bars are so good. I feel like I'm eating lemon pound cake and not a protein bar. Is that a bad thing? But seriously, we've been eating these bars for quite some time now, and I'm so glad we finally found the lemon ones. If you need a pick-me-up, a yummy snack, or just some extra protein, try the GoMacro bars; they're all really good. You will not be disappointed." —PJM

Promising review: "RUN to buy this, I repeat...RUN. I bought one of these about two years ago, and it’s STILL going strong. Aquaphor is amazing. We all know that. Buuut the convenience of having it in a tube is life-changing. It truly is as easy as one, two, three. It can easily be applied to anything you could possibly need.

Jasmin Sandal / BuzzFeed, Amazon

Alleyoop is a woman-owned small business that specializes in functional makeup products. 

Here's what former BuzzFeeder Jasmin Sandal has to say about it: "I gotta say, I love the concept of the Pen Pal from Alleyoop! After using all of the functions (eyeliner, highlighter, lip liner, eyebrow pencil) and as someone who LOVES makeup but was applying as little as humanly possible during lockdown, I think it’s a great tool for anyone looking to streamline their routine. It's ideal to use for touchups come the end of the work day, or a subtle, minimalist way to apply makeup in the a.m. The brow pencil is particularly soft and pigmented, and filled in my eyebrows quickly. I just adore the ease of application of each product, and appreciate the universal, does-it-all-for-you concept. Plus, it saves me so much room in my already-overflowing makeup bag!"

Get it from Amazon for$20 (available in three shades).

The tools are all things you might find yourself searching through a drawer for and are useful in a pinch. It fits comfortably in your wallet and will help you open a beer or tighten a screw. The coolest feature that I couldn't find on most other similar products was the credit card phone stand. It is great for planes and other travel applications (I haven't had trouble bringing this on a plane anywhere I have traveled, FYI)."—Mary

Unlike other brands (IYKYK), this is designed with a lockable straw so you can just toss this in the passenger seat of your car or your purse without a care in the world.

www.amazon.com, www.amazon.com

Promising review: "I own three of the "popular" brand stainless tumblers, but they leak like a sieve. And they are heavy! I have many chronic autoimmune illnesses, and hydration does help me, so I always have a full cup. I was interested in Brumate because I could lock it and throw it in the seat for extra water, as I tend to empty a cup every 90 minutes. It is sleek, fits my cup holders, weighs less, and is absolutely leakproof. It is a bit top-heavy, and the straw has become detached a few times. My main issue is that despite handwashing and careful handling, it has a chip in only two weeks of use." —Marissa Pro

Get it from Amazon for $39.99+ (available in 22 colors and two sizes). 

23. Or, a collapsible silicone water bottle because even though you love your refrigerator-size Stanley Cup, you sometimes need something a lil' smaller for your adventures. This is refillable and rolls up to be super compact when you're done sipping. 

Elizabeth Lilly / BuzzFeed

Promising review: "I got this the day before a cruise, and it made it so easy to throw into my carry-on and was able to fill once I got through security at the airport. I used it all through my cruise as well, and when I was done with it, I folded it back up, and it went right back into my purse at each port. People asked where I got it, and I honestly loved it. It’s a little bulky, so it isn’t slim for small purses, but my backpack and having it was nice. I will not use it for day-to-day use, but it’s another great travel find for those who travel often :)" —Mary

Get it from Amazon for $9.99 (available in six colors/styles).

24. And, a Springer leak-proof pet water bottle so even your furriest of friends can be hydrated throughout the day.

Springer Pets is a woman-owned small business run by a mother-daughter duo (and the dogs who love them). They were also featured on Shark Tank! 

Promising review: "I am extremely happy with this purchase! We have two medium-sized dogs (30 pounds and 42 pounds), and this was a LIFESAVER. We beat the heat, car anxiety, and quenching thirst by providing our fur babies with much-needed water breaks. This bottle is "mess-free" and was absolutely easy to provide water to our dogs even while we where driving. No water spills, no need for extra plastic water bottles or collapsible bowls. Throw some ice cubes in there, and you'll see it holds cool and fresh water for a good amount of time." —Tatiana

Get it from Amazon for $21.99+ (available in nine styles/colors). 

25. A belt bag that's basically a Lululemon look-alike, but for way cheaper. This has tons of storage and can be worn crossbody or fanny pack style.

www.amazon.com, www.amazon.com

Promising review: "I’m SOO impressed with the quality of this bag! I’ve worn the Lululemon belt bag and I gotta say, this is pretty similar. Almost identical, except the Lululemon is a tiny bit smaller size. The Lululemon one also has a plastic zipper but this Amazon one is metal. I prefer the plastic but this one is OK. It might be better than Lululemon JUST for the fact that they have so many color options!" —Em

Get it from Amazon for $12.98 (available in 39 colors). 

26. A pack of flushable wipes for when you're going to the bathroom and see that the public restroom conveniently ran out of toilet paper. (UGH!) Keep these individually wrapped wipes in your purse or pocket for those emergency situations, so you can go about your day without having to use a toilet seat cover as toilet paper (sad, but a reality for some). 

www.amazon.com

Promising review: "These are great for travel and when you’re at a poorly stocked public bathroom (or behind a tree, whatever the case may be). It is also great for hand-washing and removing sunscreen in a pinch. They are even gentle enough for the face.

Promising review: "Wow. I took this on vacation, during which we walked about 20,000 steps daily. And, of course, my shoes begin to rub against parts of my feet, terribly. But I smeared this on, and it was amazing. I did have to reapply a few times a day, in public, but I highly recommend this!! I used it on my toes, ankle area, etc., and my feet felt great (normal)." —Y.

Promising review: "This is the best product ever! I’ve always been an excessive sweater my whole life. As you know, that can lead to being stinky.

Promising review: "I was really surprised by how great the quality was on these sunglasses! The packaging and included accessories were good quality, too. I usually don’t care much for the extra clutter that comes with a new pair since I have many cheap pairs, but the cloth and bag were really nice material too. These sunglasses fit perfectly and have a bit of weight to them, thus keeping the quality of a great new pair!" —Amazon Customer
