They are soft and well-made, but they are definitely NOT SEAMLESS, which was my whole point in buying them. There are two cross-seams, as well as a fairly thick hem seam on the legs. If you have a problem with inner thigh or genital chafing, you may want to look at a different brand. Otherwise, these are comfortable and well made. FYI, the ones I received had a matching inner liner, not a white one as some reviewers have noted.

Buying another package

Size: Large, Color: Multicoloured D (5-pack)

Oh my gosh, I love these!!! They are very comfortable and not overly tight. The material is so thin and breathable, very comfortable. Love the colors. Am buying another package! I'm in perimenopause and these definitely keep me cooler than my tradition cotton underwear.

Comfortable but Runs Small

I got the wirarpa Men’s Cotton T-Shirt 2-pack in XX-Large (Black/Gray) and while the shirts are really soft and breathable, they do run small. The XX-Large feels a bit tighter than expected, especially after washing. The cotton material is great and comfortable, but I would recommend sizing up if you’re looking for a more relaxed fit. The classic crew neck design is versatile, and the shirts are well-made. They hold up well in the wash and maintain their softness. Even though the sizing is a bit off, the quality and price are still excellent for the value. If you’re okay with a slightly snug fit or decide to size up, this is still a great purchase!
