The Training Jammer is perfect for regular training with flatlock stitching, comfortable leg opening, drawcord and rubber print Funky Trunks logo. It’s a popular choice for swimmers and triathletes and offers and extra layer of warmth in open water when a wetsuit isn’t an option.

Made from our exclusive C-Infinity fabric, a 100% Italian polyester that is a colourful breakthrough in chlorine resistant fabric technology! The superior choice for swimmers, C-Infinity has exceptional strength and can retain its durability far beyond other elastane swimwear fabrics. Ideal for frequent pool use for recreational and performance-based swimming. 

Our mission to create renewable energy from our active customers just took a giant leap forward with the invention of our power generating trunks. Every stroke taken creates enough energy to power a light bulb for 1 second. So when our planned takeover of the global swimwear market occurs we will be able to power a single household from the combined efforts of our millions of customers.
