YES PLEASE
i just can't afford luxury brand underwear (100% organic washed cotton panties in this economy!? lol!) and took a chance on these amazing underwear after buying random pairs of all different brands, fabrics, and cuts for years and always being so disappointed and uncomfortable with most budget-friendly underwear's suboptimal fit, annoying feel, and lack of moisture wicking that i would literally just opt to go commando. i hated wearing underwear. BUT THEN... i tried one pack of these, mostly based on the price point, and was instantly converted. i wear these literally every day. i have like 30 pairs. i threw most of my other underwear out. these are my holy grail of incredibly affordable underwear. these are so soft and so cozy in the leg and waistband that i don't feel them at all during the day. not a single pair has gotten holes or frayed or changed texture in the wash after maybe over a year of wear, they only got even softer and nicer. they didn't stretch out and get those annoying ripples in the hem when i gained and lost weight (5'2 from 130lbs-150lbs and back down), size M bikini cut totally accommodated my weight gain and never felt tight, and now that i've quickly lost weight again they still fit my body perfectly to form. my weight fluctuates a lot because i have PCOS and other brands of underwear i've tried just don't cut it in that department like these do, so fear not yo-yo weight ladies. the price point is actually insane for the level of comfort and durability. you will be shocked. i do hereby put in a request that amazon essentials make a line of 100% cotton underwear because i think they would be wonderful, BUT i have to say the 5% elastane in these hasn't made me feel sweaty or stuffy. this underwear wicks moisture pretty great, even in the dead 95° of summer. if you are into 100% natural pads (not like L. or Honey Pot mainstream organic ones, the ones where even the GLUE is 100% organic plant based) just be aware those pads will not stick to these no matter how hard you try, maybe because of the elastane, but honestly it could just be bad performance of the organic glue itself. i wouldn't know because I DON'T EVER DEVIATE FROM THESE UNDERWEAR! P.S. i have a friend that also literally only wears these underwear. when we found out about our mutual underwear obsession we raved about it together for like 5 minutes straight. that's legit how good these underwear are. thank u amazon essentials underwear designers whoever u are for my 10/10 underwear. :3

3 years after 1st purchase- Great quality!
Another update: I’m shocked, I think the cotton fabric got BETTER. The newest set that I bought seems both softer & a tiny bit thicker than previously! I finally did have one pair get elastic fray after 3.5 years, but so far, these are really top quality if you just want basic cotton unders. I have noticed a decrease in skin issues in the area. Update: Do be cautious on sizing. I just realized I buy M & they fit perfectly, but I’m a solid US small (size 2-4, 5’4”, 115-120 lbs). Amazon rex S, which do fit, but just barely. The M are not loose, BUT I am a bit hippy. If you are lean in the hips/midsection probably S, but if you are a skinny person who lost weight via illness, surgery or glp-1s, maybe buy a small set at first to test size. It’s a small price to pay for this type of quality at the price point. i just realized I hadn’t bought new underwear since I stocked up on these in 2023, a major feat for me. And none have torn or frayed or gotten holes - the iron on tag hasn’t even come off. I’m just buying more because I’m moving to a three week laundry rotation. I bought these because I’m post-menopausal & still get night sweats, and because I have a staph carbuncle and cotton keeps our parts the least sweaty & bacteria-y. These are not no-show undies, they are just regular cotton underpants, but if that’s what you need - highly highly recommend! Both Walmart & Target versions were lower in cotton, and had lace that tears off within months, & those are the ones that give up & have to be tossed.

basic undies
mostly cotton, these are breathable for comfortable all day wear. the elastic bands at waist and legs aren’t covered, but do the job of keeping the panties in place. i’m a grandmother; having “granny panties” is fine by me. my only issue is that they shrivel up when laundered. they stretch flat again for folding, it’s just an extra step i could do without. at that price point, i ordered two packs. they’re worth the money, but i wouldn’t pay more for them.

Perfectly Soft cotton undies
Super happy with this purchase! I am preparing to deliver our second baby and as many moms know or may have experienced, child birth recovery is not easy by any means- whether you have a c-section or ‘regular’ birth, and wearing thongs is out of the question (at least for my experience) for at least the first 2 weeks postpartum while your body down there recovers. So these soft undies are going to be such a gift for the lady parts! lol they run true to size (I ordered a size medium based on the size guide) and they fit great, feel great on my body, and look even cuter with the little floral designs! The thick (*sigh*) hospital pads they give you to wear after giving birth are a huge pain and just not the most comfortable so these undies will go great with those and keep them in place without sliding around or coming off. The cut is perfect not too high or too low and the booty coverage is perfect too. Overall great product from Amazon and I’m most likely going to be buying more in the near future!

Best bikini underwear!
My wife has gotten 3 packs of these so far - the gray, white and black. These are her favorite bikini style underwear as they don’t cause of a line under her clothes. She says they’re very comfy and fit very well (she’s very picky with clothing and its comfort). Very breathable and soft also!

Comfy and breathable but don’t last the longest
Love these so comfy and breathable but they started falling apart after a couple of months so don’t last super long.

They are my daily wear undies
I've purchased these multiple times now and they've been my daily wear undies for probably a year and a half now, maybe longer. I've yet to see any of them have holes or seams coming apart and I do laundry with them 1-2x a week using hot water. They're comfortable, breathable enough for being cotton, & they're stretchy. I almost never get wedgies because they're truly full coverage. I also don't get overstimulated from them. I have major sensory issues when it comes to underwear and it took me years to find ones that didn't put me in a bad mood. I would definitely recommend these for all those reasons. The ONLY downside is you'll likely have visible panty lines wearing 90% of pants lol.

Super Comfortable & Great Value – Perfect Everyday Underwear
I ordered the multipack and all the colors were cute and simple. They fit true to size, and I love that they don’t bunch or dig in — you kind of forget you’re even wearing them, which is a win in my book.

Comfy, breathable and stay in place
These are so breathable, not restrictive but feel supportive at the same time- stay in place so you don’t have gathering in between bottom. Also super soft- for anyone who prefers comfort.

Comfortable and good quality
These underwear are comfortable and soft. They are well made and wash extremely well. They do not chafe or dig into your skin. And they cover all your bits and pieces while not resembling your grandmothers underwear.
