Geronimo Prism Trunk

The Geronimo Prism Trunk is a men's trunk in solid-colour cotton modal with a loud, multicolour print waistband. Each of the six colourways pairs a single-colour body with a pixel-block print band in matching tones. The White trunk adds black contrast piping on the pouch seams and leg hems. Yellow, Pink, Orange, Purple and Black keep the seams tonal for a clean block of colour. The knit is soft cotton modal with a touch of elastane, so the trunk stretches as you move. Wear the Geronimo Prism Trunk under jeans, chinos or gym shorts for colour that shows at the waist. Browse more men's trunk underwear or shop the full Geronimo range at Underwear Expert.
