Leading American men’s underwear retailer International Jock has expanded three collections of their in house brand, John Sievers, to include more colours just in time for spring. The Sleek, Highlite and Solid lines of briefs and boxer briefs come in more colours than ever to include steel grey, racing red, pastels and neon hues among others. The underwear designs by John Sievers feature the “Natural Pouch” which has a special, deeply-contoured shape that conforms perfectly to your male anatomy and leaves your genitals hang gently and naturally in the pouch.

Enjoy below some of our own recommendations but do make sure you see the collection in full before you buy. In the exclusive to International Jock photos, model Francesco Brunetti is posing in the new designs.
