1. A pair of reusable nipple pasties for those summer 'fits you just don't wanna wear an uncomfortable bra with (an extra layer is just extra heat). These have thin edges that don't appear under clothing and use a medical-grade adhesive that's gentle on skin.

www.amazon.com

Promising review: "So I decided to put these to the ultimate test for 4th of July underneath my white, semi-sheer swimsuit. I wore them out in the Florida heat in the ocean all day, and they did not budge or peel off. I thought for sure these would take skin off by the time I got home because I just couldn't believe they stayed on the entire day (humidity is real). I was able to remove them with ease. I washed them with warm water and soap and let them dry, and the next day, they were super sticky, like they were brand new out of the package again. Buying these forever." —Marisa

Get it from Amazon for $26.50+ (available in two sizes, two styles, and five shades).

Psst — it's also gluten-free, soy-free, and dairy-free! 

BuzzFeed writer Elizabeth Lilly swears by these:

"I always ALWAYS pack this stuff for trips. I recently visited Vegas for ~48 hours for an outdoor music festival. I drank one in the morning before boarding my flight, then once I got checked into my hotel, and then the next morning before the music festival, where I was outside and guzzling tall boys of beer. And I felt great when I woke up the next day! Drinking Liquid I.V. also meant I didn't have to guzzle plain water (and then stand in line for the bathroom a ton) to stay hydrated for the 12+-hour festival." 

Promising review: "I’m a tile setter in South Texas, and Liquid I.V. has made a significant difference in my ability to stay hydrated in these 100+ degree summer days." —Colton F.

www.amazon.com

Promising review: "This is one of those things that I wish I'd found years earlier. I've suffered from mortifying stress-induced under-boob sweat for most of my adult life. Also, I'm a lifelong Seattle girl who gets upset when it's warmer than 65 degrees outside. So when I stumbled upon this product, I was curious enough to buy a small pack. And yes, I've come back for MORE! For real, I won't put on a bra without one of these liners now. It absorbs all the moisture from heat and stress. And because it's a really soft bamboo/cotton mix, my skin is finally not feeling tortured under there! To the makers of this ingenious, life-changing product: thank you, thank you, thank you! Sincerely, all the grateful ta-tas you've helped to care for." —Niko

Promising review: "I was hesitant to buy this product because I wasn’t sure if it would work or not, but WOW!!!!! It works!!!! Amazing!! I’ve been to a music festival for the past two years, and from walking too much, I’ve gotten the worst chafing. This year, I decided to buy this and use it during my two days at the music festival. No chafing whatsoever!!! I did reapply a few times (because I was walking tons/sweating). But seriously, this product is wonderful. I tried deodorant last year, and that was no help for me. This is my new go-to, and I’m excited to use it more this summer! Buy this!" —Queen268

Amazon

Promising review: "I have always suffered from bad odor on my underarms since I have very delicate skin, so I can't use strongly scented deodorants. I'm always trying out cream deodorant or gels, but it either irritates my skin or it doesn't stop my bad odor. THIS IS THE BEST INVENTION EVER. I LOVE IT! I can't believe that something finally works! My armpits don't smell bad. I can finally move my arms freely. The scent is wonderful; I love the smell, and it's not harsh on my skin. Even after a long day, my underarms are still smelling like coconut." —Vicky Reyes

Dries quickly, lasts longer, does NOT make your skin stinky, applies evenly, and you get a fair amount of product!! Other tanners I've used become VERY noticeable when they start fading.

Promising review: "This stuff is legit amazing. Mississippi heat down here — 'real feel' is 111 most days. My hair usually starts to look frizzy and sorta funky wavy in some spots as soon as I leave the house due to the ridiculous humidity we have here. I am so impressed. Somehow, it gave my usually flat-to-my-head hair some volume as well. All I did was shampoo, conditioner, towel dry, and then blow-dry with tension like the back of the bottle says." —ChrisandLeslie

Amazon, www.amazon.com

Promising review: "I have super oily skin and am always looking for something to help control it during the day. The linen squares are good, but you have to keep them around (and keep replacing them), and they end up in the landfill. This little contraption really works, and I just rinse it at the end of the day and start over again the next. I kept one on my desk and bought a second for my purse.

I'm in the big heat wave, and it's been over 100 every day for the last week with no sign of it letting up any time soon. These are quick and easy, and the cold water bottles have been the only thing helping me sleep in a room anywhere between 80–90 degrees at night. I love the lids!
