So comfortable and worth the buy
Size: Large, Color: Black
So comfortable!!! There is no seam in the butt and under neath, only in the front but it is really soft and non irritating. I got these for post partum but I’m already wearing them at 8.5 months pregnant. They’re probably my favorite undies right now. The length is also perfect and the material is very soft and stretchy. The waist band is the same, soft and stretchy.

Cotton Blend Was Just Too thick
Size: 3X-Large, Color: Black
I was surprised by how thick these boxers were, thicker than my jeans, much thicker than my PJs! Thick enough that I could wear them outside the home without jeans. In spite of the thickness, they were soft and very comfortable. The 3XL is a perfect fit on my 5’2” apple shaped, short waisted 215 lb body. The boxer cut helped prevent chafing, a major plus. Menstrual pads, with or without wings, do not adhere to this material, a major minus. Ultimately, feeling like I was wearing jeans to bed or wearing two pairs of pants outside the home, was just too uncomfortable for me. So disappointed because these boxers were such a great and comfortable fit.

Love the "B00" Colors, but the "RX" colors are a totally different boyshort!!!!
Size: 3X-Large, Color: B004
The packs that have a color name starting with "B00" are fantastic! I bought the black and grey ones, and a set of the multi-colored ones, and they are the best boyshorts, ever!!! I attest to this now, after 6 months of everyday wear and wash.
This first part of this review is only for boyshorts that have a color name starting with "B00"! Read the end for my review of the ones with a color that starts with "RX". Completely different panty.
The B00 colors are sewn impeccably well, and they are a beautiful, quality material that resembles very thick, very soft leg stockings (panty hose). They stretch easily in every direction, so they hug your curves perfectly. These are not cotton! I hate cotton undies. These are nylon, or something synthetically similar.
Unlike stockings, I think it would be very difficult to put a snag in the material because of how much thicker the material is than stockings. I actually tried to snag them with my torn finger nail just to see, but the material is very strong, so I could not put a run in them.
Even though these are thick and soft, they dry remarkably fast, because of the looser weave of the synthetic material. They do not roll at all at the waist or on the legs, and I am a very curvy girl, so if they were going to roll, they would definitely roll on me.
They wash very well. I've machine-washed them all weekly for 6 months now, and also tumble dried them on the low setting, at a laundromat. No issues at all with fading, color-bleed. shrinking, ravels, and no pilling. These are definitely my everyday undies.
One really nice feature is that since these are tagless, they sewed a few raised lines of soft stitching in the back, so you'd always know where your rear-end goes.
One thing some people may not like, is that there is no separate liner on the crotch. It is pretty much the same material as the rest of the panty, but a bit thicker, with an extra light layer of lighter-colored stitching incorporated into the inside of the fabric, to make it a bit more absorbent. I actually prefer this, because it means they dry faster, and they are less likely to fall apart in the gusset, but some people may prefer the extra liner of fabric that is typical for most undies.
These are not binding at all, so not a shaper panty by any means, but they are certainly very comfortable and stay where you put them.
I would think these would be fantastic for backpacking (I love backpacking!) for all the features I mentioned. I have micromodal boy shorts by meundies that I used to wear for hiking, but I will definitely wear these instead because of the reduced drying time after washing, or when sweating. The other micromodal bamboo/cotton-like materials just hold too much moisture for hiking. Undies that retain moisture can cause painful chafing, and can even contribute to hypothermia.
I love these! I am buying more!!
REVIEW UPDATE!
Well, I did buy more. I bought the 5-pack of color that starts with "RX", and I was super disappointed! The "RX" ones are NOTHING like the "R00" ones I described above. Look closely at the pictures. Those ones with a different fabric panel on the hip are tight, not nearly as stretchy, roll instantly on my inner thighs, dip in the back, are not nearly as soft, and do not dry quickly. They are a completely different boyshort, and I do not like "RX" model of boyshort at all. I suppose if you had no meat on your thighs and you wanted a shaper-type panty, the "RX" might be exactly what you're looking for, but not for me, for sure.
