Made from 95% cotton and 5% spandex, the Amazon Essentials Bikini Briefs check off the first box on our list of requirements. Cotton is as breathable as it gets, so wearing them all day is a breeze. The packs include adorable color and pattern varieties, whether you’re looking for solids, stripes or fun animal prints — which brings us to number two on our list: cuteness. As for comfort and fit? We’ll let the five-star reviewers (all 101,000 of them!) speak to that.

Feels like wearing nothing

“They are so comfortable and give me full coverage so I feel secure,” writes a five-star reviewer. “The fabric is so soft and breathable, I never want to take them off! The waistband is thick and doesn't dig into feels like I'm wearing nothing. They come in a variety of colors, so you can get one that matches any. Highly recommend these!”

The search is over

“I came back to buy more and saw my last order was placed over 2 years ago, and I’m wearing them as I write!,” writes a satisfied shopper. “For weekly wear for over 2 years they’ve held up better than most underwear I own! I really love them because my scrub pants sometimes irritate the skin on my behind if I wear a thong, but I hate panty lines, and these are PERFECT. The simple cotton makes my skin happy and the thin elastic edge hides panty lines beautifully. They’re comfortable, don’t dig in at all and don’t slide down.”

Perfect fit

“Perfect fit for my tush!” says an enthusiastic reviewer. “I hate hate hate buying underwear but decided to take a chance and just order a pack this time. These are the perfect, most soft breathable pair I have worn! Normally I going commando as quickly as possibly but with these I hardly pay attention to having them on.”
