Cool Cotton Trunk 4"

About this find

These Tommy John Cool Cotton trunks have a 4-inch length and are made from 86% Pima cotton and 14% spandex. The Pima cotton gives the fabric a soft, premium feel, while the spandex adds stretch so the fit can move with you. They are designed for daily wear, so they slot right into your regular underwear drawer.

The fabric is breathable and moisture-wicking, so sweat can evaporate quicker. These trunks keep you 2-3x cooler and dry 4-5x faster than regular cotton, thanks to more breathable, efficient fibers. That makes them a smart pick for warm days, busy schedules, or any time you want a lighter, drier feel.

The horizontal Quick Draw fly opens sideways for fast, easy access, instead of the vertical or no-fly openings some underwear uses. The curved contour pouch is designed for comfort and control, supporting your natural shape without restriction. The stay-put waistband won't roll, bunch, pinch or leave marks, and the tagless label keeps things comfortable against your skin.

Machine wash cold and tumble dry low. The model is 6'2" with a 32" waist and wears a size medium, which gives you a handy point of reference when choosing your size. Pick the size that matches your waist measurement, and you will have a pair built around the fabric, fly, pouch and waistband details above.
