The CYBEX Sirona S is the only Convertible Car Seat in the U.S. to feature an innovative 360° rotatable seat with load leg stability, linear side impact protection, and SensorSafe™ technology. The rotating feature makes it super easy to get your child in and out, and also convenient for switching between rear-facing and forward-facing positions. The load leg helps decrease rotation of the car seat while the side impact protection system absorbs impact forces in certain crashes. Built into the chest clip, SensorSafe provides app alerts when potential unsafe situations arise. These features offer advanced safety protection for children and greater peace of mind for parents.

So comfortable!
Color: (3 Pack) Skin, Size: Large
These boyshorts are so comfortable. I'm really glad I got them. This is actually the second order I've gotten. I ordered them before & got a size larger. The seller was so kind in making the exchange. Originally, I went to return them via Amazon & was told that I couldn't exchange them & that I had to return them. After sending a note to the seller I received a very nice message back from the seller & he sent me the smaller size. I was very grateful, especially because they'd been on sale when I first purchased them & they were no longer on sale, so repurchasing them would have cost more. I highly recommend this seller. It means a lot to me to be able to work with a merchant who is customer-centered & was willing to work with me in getting the right size.
The underwear is made from the softest, silkiest fabric. Seams are heat fused, so they don't have the typical ridge where the seams are located & they don't show through your clothing. The crotch portion is a bit odd. The cotton panel goes side to side, rather than front to back. I'm sure they're designed that way because it's more efficient to make them that way, but they don't accommodate a pantiliner very well. Since pantiliners are attached front to back, you have to attach it to the fabric of the panties in front & back, rather than have it attached to the liner itself. The crotch has regular fabric on the outside & a piece of cotton on the inside. The two fabrics aren't always well matched, so sometimes the outer fabric is rumpled because it isn't flat against the cotton liner. I took off a star for that.
That said, these are the most comfortable underpants I've ever worn. This style is not designed with tummy control, just so you're aware. I didn't want tummy control because I find it uncomfortable. It conforms nicely to my bumps & bulges. LOL.
They are so smooth & soft. Clothing slides over them effortlessly. Honestly, you can barely tell that you're wearing them. They wash beautifully with no need for special treatment. I just throw these in the washer & then the dryer afterward. When you pull them out of the dryer, they beautifully smooth & wrinkle-free.
As I mentioned above, this was my second order of these. After putting on those I first purchased, I knew I wanted more & I'm glad I got them. They're so comfortable to wear & are not visible through your clothing. I'll be back for more when I need some.

Finally, a pair of boy shorts that fit well, have a gusseted crotch and are so comfortable. I hope they keep making these because they are great.

Buy them!
Color: (6 Pack) 2-black 2-beige 2-white, Size: Large
Better than I was expecting! Its hot and humid here, while also being windy, so wearing sundresses is necessary, but scary. Lol These cover everything and are so silky soft. They're also stretchy enough for you to not feel like you're wearing anything at all. So comfortable. 10 out of 10.

Boy Shorts for comfort, stretch and just enough firmness ( but not too much.)
Color: (3 Pack) Black, Size: X-Large
Finally a perfect boy short in every way! I have ordered and returned so many boy short brands up to now. SHARICCA BoyShorts Panties are comfortable, soft, stretchy and the perfect length for me. I wear an XL and am 5’5”. I just reordered the 6 pack and these will be my go to for underwear! Thank you customers for your reviews which helped me decide to try.

Very comfortable, right length
Size: Large, Color: Black,grey
This product arrived as described. I like the trunk length, not the boxer brief length. They are comfortable. Hold up well when worn and washed. I don't seem to sweat as much. These were ordered to replace ones ordered about 2-3 years ago due loss of weight, had to down size. The waist band doesn't roll as like other brands.
