Boy have I bought A Lot of Underwear
Size: Medium, Color: Black,navy,melange,london Blue,burgandy
These are my favorite boyshorts so far. The little stripes kill me, they're so cute. I am now an expert on boyshorts. You should know, I always buy the color packs with boyshorts with a make-up that look like static on the tv. Not sure how else to describe that but they tend to be the same across the board and I think they're super cute, personally. The solid colors may be a different story. SO-Here's what I've learned: They're all basically the same, minus the material and how you like them to fit. You want to look at what the exact material content is. Do you like super soft, almost gauzy and you're not concerned with possibly snagging them? Then you'll want to find boyshorts with a high percentage of polyamide. These are not them. These are about 50/50 polyamide and polyester, which is firmer and has less stretch. Not gonna snag them in regualr situations. Still lots of stretch, though. Just more support and more excercisey material feel. But, there is enough polyamide in them to still feel soft. I prefer less plush and more support. There is a dash of spandex in there and that's good to accommodate many bodies and to hold their shape over time. I know some gals are looking for a softer, stretchier, plushy boyshort. They're easy to find. Look at the material listed. Okay, about sizing: These are stretchy. Not SUPER stretchy, like the gauzier underwear, but stretchy, and you'll fit in most of the sizes. The fit will just be different, obviously. I'm a large in regular pants typically. Size 12. Ten in a good month. I'm 48, 5'5 and 165 pounds. I've got a booty, but not super-duper bangin. Just big. Anyways, I've gotten my "true" size (L), sized up (XL) and sized down (M). Sizing up (XL) is too "poochy" feeling and just mildy wads up around where my legs meet my bits. Comfortable, and stay on but saggy feeling to me. The true-to-size, size large, are less "waddy" and fit fine! Loose enough to almost forget they're on. I've sized down to medium, and that's where my preference is. They fit like I have work out shorts on, just very short ones. More support but don't look ridiculous. I don't look like a sausage in them. Size small would be that on me-the sausage shorts. I mean, I'm wearing these around the house in the summer so I don't have to crank my A/C., and for bed. They aren't gonna be seen my many. Either way these are going to roll up (super skinny gals without thigh gap...do boyshorts roll up on you too? Always wondered that) but the smaller size on me seems to roll less, and that roll doesn't bother me. A roll is different from a "wad". Actually I wouldn't even call it a roll, I'd call it a "fold over". Ha ha I hope this helps and you understand my lingo. FYI I have found personally that most of these brands are the same exact thing from China, packaged and branded differently. The material is the big factor. But these are the only ones I've found with little pinstripes. CUUUTE. Good luck out there!

Great product
Size: Medium, Color: Black,navy,melange,london Blue,burgandy
I adore these! They're so comfy. When they first arrived they felt a little snug in the waist and leg holes, but I gently stretched them out before putting on and have had no problems since, even after washing/drying, i just put on delicates cycles. The slight snugness normally wouldn't bother me at all and most of my other undies are tighter, but I had surgery for endometriosis back several months ago so I need/needed something comfortable. I'm used to wearing hip huggers or bikini briefs.
I was concerned that boyshorts would ride up or that the legs would roll-which they do roll up slightly, but it's easy enough to adjust when putting on clothing and then I have no issues!-Once I tried these, they've become my favorite underwear. They're very soft and "seamless" and I like the fact they have no elastic. I have pain down my inner thighs that makes seams or elastic leg holes uncomfortable, but these undies are long enough and soft enough to provide coverage/protection in that area when wearing pants or leggings with inner seams, and makes it so much better to deal with.
I just ordered another package and I'm excited to have more pairs to replace my old undies with! Really happy with this purchase.

A Bit Too Smooth
Speaking as a petite person, these following boyshort underwear passed so many comfort levels down from the fit, stretch, fabric feel, and describe shape of the material. When it comes to undergarments and living in a hot desert, breathable clothing is a necessity. It maybe "just underwear", but they are very complementing on the body and invisible in your movement.
The crutch however, while the soft fabric maybe great with skin-contact - results with little grabbable or stickable surface for pads or panty liners that I own. Not having tried alternate pad or liner brands, I can't give a thorough idea of "Does it stick?" when it comes to this underwear. It's not to say it is completely unstickable, it'll will stick, but you really need to press in place. Major movement will crunch the pad/liner and you'll have to replace later in your day because you will feel it amiss.

Incredibly comfy and sexy but watch for health variables
Size: Large, Color: 2 Black,2 Blue,light Coffee
I love these so much. Incredibly comfy and no more awkward panty lines (with no awful thong string needed).
I would have absolutely loved a grayscale-colored pack (black, gray, ivory). The gray ones are fantastic and subtle if the top band sticks out a bit with jeans (I thought the blue ones would blend better, but they stand out in a weird way? Maybe a darker denim color would be less noticeable.) These are SO comfortable I actually enjoy getting dressed in the morning more, lol.
My husband also really likes how these look. I feel way more everyday-sexy than regular cotton briefs or bikini-style underwear or the like.
*A big thing to be aware of is that these do not breathe the same way as cotton, so you need to make sure your netherparts get adequate opportunity to air out so you don’t get a yeast infection. Your vaginal ecosystem will get out of balance if it’s too hot and/or compressed on a regular basis (like with yoga pants or etc.), so make sure to trade off with other more breathable underwear and give your body time to breathe and cool down.
If this same company also made 100% cotton boyshorts in a multipack, that would be all I’d ever need!

10/10 would recommend
Size: 3X-Large, Color: Light Coffee,grass Green,blue,orange,black, Size: 3X-Large, Color: Light Coffee,grass Green,blue,orange,black
I have bought 2 packs of these now, I love them! I wear them mostly to bed or under sweatpants, they're super comfy and good coverage. I don't really care about how these look, I just like not feeling like my underwear is too small for me with my belly or my butt hanging out! I followed the size chart and 3XL sounded way too big but these fit great, tight enough to stay up but don't hurt or leave marks on my thighs/stomach. (for reference: 5'5, 200lbs, waist 32, hips 46)
