This BRODDLE jockstrap is made of thin, soft, silky nylon-spandex fabric, with the waistband, the nether straps and the reinforced edges of the pouch being of a more sturdy material. It’s very well made, with no faulty seams, missing or loose stitches or any other noticeable flaws. It seems as robust and durable as any such item of clothing can be.The pouch is seamless--a nice feature, and a welcome difference from the many other jockstraps that I’ve received through the Vine program, most of which have a thick seam at the center of the pouch--and it’s the perfect size, shape and volume for my anatomy. ‘Nuf said. YMMV, of course.The waistband is slightly but not overly stretchy, so it’s important to choose the appropriate size; there’s not much room for error. The sizing info says the Medium that I ordered fits waists from 31 to 32 inches; it fits comfortably, if just a little snugly, on my roughly 32-inch waist.If you’re a fan of this style of wedgie-resistant underwear, this BRODDLE version is a great example of the genre. I rate it at five stars for design, materials and quality.
