I have a love-hate relationship with bras and underwear, and I really think it's because I just can't seem to find many that are comfortable. The struggle spurred my curiosity about the kinds of undergarments other shoppers are turning to for comfort and support. The weird but genius bras and underwear you won’t believe people are buying on Amazon run the gamut from cozy to athletic — but they’re all surprisingly practical in some way.

If you have a desk job or travel often, it can be a challenge to find bras that don't feel like they're poking at your ribcage while you’re sitting yet still give you the support that you need. (I know that when I find a truly comfortable bra that does its job and fits correctly, I usually buy more than one.) It can also be a hurdle to find sports bras that actually support larger busts, regular bras with straps that stay put, and options that you can wear with backless, strapless, or low-cut tops.

And then there's underwear. From moisture-wicking fabrics to designs that won’t ride up, there are a ton of underwear designed with comfort in mind. Amazon shoppers have also raved about undies with more unexpected features, such as pockets to stow away valuable when you travel or padding for riding a bike.

You might be surprised by all of the unexpected and ultra-practical bras and underwear on Amazon. Scroll down to check out 22 options that Amazon reviewers have tested and loved.

1

Panties That Prevent Leaks During Your Period

These period panties have an absorbent, leakproof layer, so that you can wear them either alone or as backup with a tampon, pad, or menstrual cup. They're also constructed with a moisture-wicking, breathable bamboo fabric that reviewers have confirmed is soft to the touch.

  • Available sizes: XX-Small 6X-Large
  • Available styles & colors: 8

According to one reviewer: “I bought these because I don’t like to sleep in tampons, but sometimes that’s when I have my heaviest flow. These were perfect. Comfortable enough to sleep in. Absorbent enough to keep me and my sheets clean. They don’t feel soggy like I thought they would! Easy to care for. SO glad I got the three pack.”

A Bra That Lets You Go Backless And Strapless

If you're wearing a backless style, a silicone "sticky" bra is a great alternative to going braless. The adhesive cups stick to your breasts and stay in place all day, but come off easily when it's time to remove them. They're great because you can customize the amount of cleavage and push up you want by simply adjusting the placement of the cups.

  • Available sizes: A — E
  • Available styles & colors: 3

According to one reviewer: “The sticky bra stayed in place all night, even in 100° weather! It was easy to put on and very comfortable.”

These Moisture-Wicking Panties That Keep You Dry

If you know you'll be working out, opt for a pair of moisture-wicking panties instead of cotton ones. They dry faster and are more breathable than cotton. Plus, these are made with odor-preventing materials as well, to help you feel fresher after a visit to the gym. These seamless and tagless panties come in packs of three, and there are 15 different packs to choose from. Prefer a thong style? Try these Balanced Tech underwear instead.

  • Available sizes: X-Small — X-Large
  • Available styles & colors: 15

According to one reviewer: “I absolutely love these undies. [...] I do HIIT kickboxing 4-5 times a week and only wear these undies. They NEVER smell bad, never bunch or roll down, never feel uncomfortable, slight show lines through tights but nothing much. These are my go to underwear!”

4

A Seamless Bra That Almost Feels Like You’re Wearing Nothing

This bra is beloved by customers for its seamless design. “I love how comfortable this bra is,” one reviewer raved. “I can wear it all day and night and it feels like I’m wearing nothing.” It’s made with a soft, stretchy nylon-spandex material that feels as good as it looks. Plus, it does away with a thick band, which can feel constricting, and also features wide straps and removable foam cups.

  • Available sizes: X-Small — 3X-Large
  • Available styles & colors: 17

According to one reviewer: “This bra is so soft and comfortable. It is hard to go back to a ‘regular’ bra.”

This Underwear With Secret Pockets To Keep Your Things Safe

If you travel a lot, you should think about picking up a pair of undies like these, because they keep your important belongings safe inside their hidden, zippered pockets.

If you find yourself dealing with under-boob sweat throughout the day, then you'll love this everyday moisture-wicking bra.

7

This Shorts-Style Underwear That Prevents Chafing

Chafed thighs are a painful, but totally avoidable, problem. Shorts-like underwear made with a smooth fabric, like this pair of AmazingJoy’s panties, can allow you to move around without causing friction and protect against thigh-irritation.

  • Available sizes: X-Small — 3X-Large

A Bra That's Perfect For Low-Cut Necklines

A Sports Bra With Double The Support

If you have larger breasts, you might find it hard to find a sports bra that provides you with the support that you want. If you’ve ever resorted to wearing two bras at once, you might try this full-coverage one instead. It has a double-layered design to offer extra support while you work out.

  • Available sizes: 34C — 50J
  • Available styles & colors: 10

According to one reviewer: “I love this! It fit perfect and I love how high up it goes in the chest area. If you have a shirt/top that is a bit low it looks like a shirt/top underneath. Like you’re wearing two tops but you aren’t. It’s soft and very comfortable. I had a shoulder injury and straps always hurt, these don’t and are very comfortable.”

The Underwear Equivalent Of A Padded Bra

Super comfortable underwear/panties.”

A Pair Of Padded Underwear For Bicycling

This pair of undies is made with cyclists in mind. The nylon-spandex underwear with flat-lock stitching is made to wick away sweat and minimize chafing. The coolest feature is the padded liner, which helps keep you comfortable on long rides. While the liner provides support, it won’t show underneath shorts or leggings.

  • Available sizes: X-Small — XX-Large
  • Available styles & colors: 6

According to one reviewer: “Have another padded pants that works well, but is almost too much padding. When not on the bike, it feels a bit awkward and at times even uncomfortable.
