If you want something that’s not to long, and not too brief, these mid trunks sit quite nicely in the middle. Made from our ultra comfy Merino+ fabric, (it’s the same epic fabric we use in our Ultra range of tops!), they deliver all the comfort and performance you’ve come to expect from our premium merino fabrics, in a classic mid trunk fit. So they’re shorter than our Altitude Boxers, and longer than our Ultra Trunks. Tag-free labels, flatlock stitching and a flexible, ultra-soft ioMerino elasticated waistband help eliminate chafe and bulk and maximize comfort. Say goodbye to ordinary undies, and go with Men's Ultra Merino Mid Trunks.
