Description
xOur scientists have finally unveiled the first-ever human submarine by enclosing a thin layer of liquid in our swimwear that wraps around your body while swimming. This allows you to sink silently to the bottom of the pool and proceed to swim along the bottom like a stealth attack submarine. If you need to resurface simply blow air (from anywhere) to expel the liquid and you will rise back to the surface. The next step is to instal sonar technology and torpedo bays so you can locate and destroy other swimmers in the fast lane.
This print has been produced via the latest direct digital printing technology, which means it is better for the environment as there is minimal wastage and water consumption in the printing process.
Lighter colours in prints can reveal more of the body underneath when wet. Science hasn't yet solved how to stop light from passing through lighter fabric colours that are wet, rather than being reflected. If you're not comfortable with lighter fabrics, we strongly recommend finding a darker print from our collection.
Life's pretty simple when you're a swimsuit, especially when you're me. I've wound up my sides to give you 12cm (slightly larger on larger sizes) of real estate on your hips and a single front panel that is fully lined.
ECO C-INFINITY is the same superior quality polyester construction that you've come to trust from our 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 you swimming day in and day out in the brightest swimwear on the market.

Shop Funky Trunks Boys Swimwear →How to Measure — Funky Trunks Boys
Measure in centimetres with a soft tape measure taken directly against the skin or over light underwear. Use both measurements to find the best fit in the table below.
- Waist — measure around the narrowest part of the waistline, usually just above the belly button. Keep the tape parallel to the floor.
- Hips — measure around the fullest part of the hips and seat. Keep the tape parallel to the floor and ensure it sits flat all the way around.
- If your measurements fall between two sizes, speak to a member of staff at Allens for advice on the best fit for the specific style.

Fit Notes — Funky Trunks Boys Swimwear
- Size based on waist and hip measurements. If measurements suggest different sizes, use the waist measurement as the primary guide for trunks and the hip measurement as the primary guide for jammers.
- The Training Jammer is designed for young competitive swimmers — it provides hip-to-knee coverage and a close fit. If your child is new to jammers, check the hip measurement carefully.
- The Sidewinder Trunks are more relaxed in fit with a wider elastic leg opening — a good choice for swimmers who prefer the freedom of a trunk over a jammer.
- ECO C-Infinity fabric is 100% chlorine resistant and built for regular training. Rinse in cold fresh water after every session and allow to dry naturally away from direct sunlight.

Frequently Asked Questions — Funky Trunks Boys Swimwear
Measure your child's waist and hips in centimetres and match to the size table above. UK sizing is the primary reference — US, AUS, and France equivalents are also shown. If measurements fall between two sizes, speak to a member of staff at Allens for advice.
The Training Jammer provides hip-to-knee coverage with flatlock stitching and a front pouch lining — designed for young competitive swimmers focused on performance. The Sidewinder Trunks are a shorter style with 12cm sides, a single front panel, and a wider elastic leg opening — better suited to swimmers who prefer the freedom and practicality of a trunk for training and recreational use.
ECO C-Infinity is Funky Trunks' premium chlorine-resistant polyester fabric, manufactured from end-of-life plastic water bottles. It offers the same superior quality and performance as the standard C-Infinity fabric — 100% chlorine resistance, 50+ UV sun protection, and exceptional colour fastness — while reducing environmental impact by giving new life to waste plastics. The fabric is milled in Italy.
The Funky Trunks Training Jammer is a training swimsuit designed for regular pool use. It is not a FINA-approved racing suit and should not be used for competition. For competitive racing, a World Aquatics-approved racing jammer is required. The Training Jammer is, however, an excellent choice for club training and squad sessions.
Rinse in cold fresh water after every session to remove chlorine and salt. Allow to dry naturally away from direct sunlight — do not tumble dry or wring the fabric. The ECO C-Infinity fabric is 100% chlorine resistant and designed for regular pool use. With proper care the prints and fabric will maintain their quality for longer.
The boys' size range covers sizes 22 to 30, corresponding approximately to ages 6 to 14. However, children develop at different rates and age is only a rough guide — always measure waist and hips using the size table above for the most accurate fit. Size 30 transitions into adult sizing for some styles.
Flatlock stitching is a technique where the seams lie flat against the skin rather than creating a raised ridge. This reduces rubbing and irritation during long training sessions, making it particularly useful for young swimmers doing high volumes of pool work. It also contributes to a smoother, more streamlined feel in the water.
