Product comparison
Compared within this brand.
| Second Skin Ribbed Running Short Length: 8.25" (21 Cm): Choose this if you want a slim, form-fitting mid-thigh running short with an 8.25 inch (21 cm) inseam, a built-in micro-perforated underpant, and Polygiene® technology that is stated to eliminate odour and prevent bacteria growth. It suits runners who prefer a ribbed stretch nylon-blend fabric (80% reprocessed nylon, 20% spandex) with an elastic drawstring waist and a hidden zip pocket at the back. It comes in Black in sizes SMALL through X-LARGE, and its fitted, second-skin silhouette may not suit anyone wanting a looser-cut short.[1,2,3] | Minimalist Stretch Short With No Undergarments 7" Length: Choose this if you want a mid-thigh 7-inch inseam training short designed to be worn without undergarments or a liner. It is made of light stretch fabric (90% recycled polyester, 10% spandex) with Polygiene odour-eliminating technology, an elastic waist with inner drawstring, front slit pockets, and a hidden side-seam zip pocket. It comes in small to x-large in Black, Grey, or Mossy Green, though the minimalist design means there is no built-in liner to rely on if you prefer wearing underwear or a separate base layer.[4] | Built-In Liner Stretch Jersey Short Length: 4.5": Choose this if you want a short, two-in-one athletic short for racquet-sport-inspired training: a relaxed outer shell over a tight-fitting built-in liner, in full-stretch nylon-spandex jersey with a 4.5 inch (11.5 cm) inseam. It adds practical details like an adjustable drawstring waist, slant front pockets plus a zip rear welt pocket, micro-perforations at the crotch, and retailer-claimed Polygiene odour control. Note that Navy/Midnight Blue is offered only in sizes SMALL and MEDIUM, and the stretch and odour benefits are retailer performance claims rather than reported user results.[5,6,7] |
