| 5" Mario Uniform Boxer Brief: Choose this if you want a playful, logo-forward boxer brief from Undz (in association with Le 31): it has round yellow UNDZ badge prints on the front and rear hips, a red elastic waistband and yoke panels, and a vivid royal blue body. The breathable stretch Maxvent polyester jersey (95% Maxvent polyester, 5% spandex), double-layered front with defined pouch seams, and 12.5 cm (5 inches) inseam suit those preferring a fitted mid-thigh cut in sizes small to X-large. Note that Patterned Red is the color listed for this variant, so it may not appeal if you're after a plain or neutral look.[1,2,3] | 5" Kong Boxer Brief Polyester: Choose this if you want a slim-fitting, 5-inch-inseam boxer brief in stretchy, ultra-light Maxvent polyester (95% with 5% spandex) that wicks moisture and dries quickly. It suits those who like bold graphic styles, with a full-coverage jungle print featuring bananas and apes, a double-layered front, and an elastic waistband. It is only offered in Patterned Green, so pass if you prefer a subdued or solid look.[4,5] | 5" Tiger Boxer Brief Polyester: Choose this if you want a statement pair from UNDZ's street-art-inspired designs: this variant has an all-over tiger print on a dark background with yellow contrast stitching and a plain black elastic waistband with a small yellow UNDZ label. Made of ultra-light, stretchy Maxvent microfibre (95% polyester, 5% spandex) that wicks moisture and dries quickly, with a 5-inch inseam and double-layered front; the listing records it in size SMALL only, so it suits shoppers needing that size.[6,7,8,9] |
