NEW! Funky Trunks Boys Sidewinder Trunks Wildermess

I’ve got a drawcord to keep me locked in position and a wide elastic leg opening and waistband for added comfort around your hips and legs. Compared to my other trunk friends, I’m a skinny runt but still very comfortable to have around and I’ll go the distance to be with you as long as you keep swimming.

Made from the exclusive ECO C-Infinity fabric which has the same superior quality polyester construction that you’ve come to trust from the C-Infinity fabric, but manufactured from end-of-life plastic water bottles. Providing 100% chlorine resistance and exceptional colours, ECO C-Infinity gives a new life to waste, reducing our environmental impact and keeping our customers swimming day in and day out in the brightest swimwear on the market. It 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.

Available in boy's sizes 24-28.  See size guide for further information. 

The Boys Classic Trunk is being replaced by the Sidewinder Trunk.  The styling is almost identical and sizes now align with the Training Jammer. 

Approximate equivalent sizes are as follows:

Size 24 = age 8

Size 26 = age 10

Size 28 = age 12

If you require a size 30 (boy's age 14 equivalent) it is now available in the men's range.
