NEW! Funky Trunks Boys Sidewinder Trunks Melting Mayhem

Funky Trunks Melting Mayhem Boys’ Sidewinder Trunks offer a slim, athletic cut with 14cm sides and a fully lined front panel for comfort and support. Designed for young swimmers who prefer a modern, streamlined silhouette, these trunks feature a secure drawcord waist and wide elastic leg openings to stay comfortably in place. Finished with a rubber-print Funky Trunks logo, they are built for durability, performance, and standout style in every training session or race.  The Boys Sidewinder Trunk has replaced the Boys Classic Trunk.  The styling is almost identical and sizes now align with the Boys Training Jammer.  If you require a size 30 (boy's age 14 equivalent) it is now available in the men's range. 

Made from the exclusive ECO C-Infinity fabric, these Trunks combine superior quality with environmental responsibility. Constructed from recycled plastic water bottles, this 100% Italian polyester fabric offers 100% chlorine resistance and vibrant colours that last lap after lap. Its exceptional durability and stretch make it ideal for frequent use in both casual and competitive swimming.
