Either you/your boy already loves long swimming trunks - or you don't. However, after massive development and testing of these Watery Surfy Eco Jammers for boys, we're pretty sure that no matter what camp you or your boy is in today, any boy will fall in love after trying these on.

The model in image 1 is 144cm tall / 10 years / 65cm around the waist and wears a size 10-11 years.

These long swimming trunks for boys are made from our unique signature material AquaFlex Eco, which consists of 100% polyester (55% of which comes from recycled plastic bottles), so you/your boy get the only available pair of jammers in sustainable materials that are also ultra chlorine resistant (+500 hours in water).

The design is also kept simple and stylish with a discreet white logo in the top left corner and nice details that spice up the swimming trunks, as well as a side length that ends slightly above the knee. After +90 tests on boys aged 3-15 years, we have managed to hit the sweet spot on the length, where they are neither too short and thus sit halfway up the thigh, but also not so long that they sit above the knees. You or your boy will definitely experience the instant gratification that this gives anyone who has tried the opposite before.

Surfy Eco Jammers are great for any water activity - they're cool enough for the beach and ultra chlorine resistant for the pool. And you won't feel a thing (and that's what makes them so special).

Special sustainability and durability combined in these Surfy Eco Jammers

These long swimming trunks are produced in our unique Aquaflex ECO material consisting of 100% polyester, of which 55% is recycled from plastic bottles made from repreve yarn and 45% is PBT polyester.

This composition offers several specific benefits:

  • 100% chlorine and UV resistant, so both fit and colors are maintained through +500 hours in the water
  • UPF +50 UV protection
  • A uniquely high level of breathability
  • Equipped with a 4-way elastic fabric that gives you the necessary feeling of freedom in your swimming trunks.
  • Oil and sunscreen resistant and antibacterial, so you don't have to wear a heavy pair of swimming trunks covered in various oils and sunscreens that stay fresh again and again
  • Water-repellent and water-resistant, so they don't absorb water and won't become heavy to swim with and you'll find yourself floating more naturally through the water.
  • The fact that the swimming trunks are actually made from recycled plastic bottles that have been collected from the world's oceans is possible because of a demanding post-collection process. This involves crushing the bottles into small flakes, going through adaptive heating and cooling and ultimately becoming the strongest and most durable recyclable sewing thread in the world. But while this process is demanding, compared to a brand new virgin fiber, fewer emissions are emitted. emissions, less water is used and only new crude oil is used along the way.
  • The elastic at the top edge and the sewing thread around the leg cutout of the swim trunks have a major impact on their durability, as they often become loose after trips in chlorinated water. In Surfy Eco Jammers, the particularly chlorine-resistant Fratelli Leoni ® elastic is chosen, which retains its elasticity up to 3 times longer than normally used swimwear elastics due to the special pre-treatment of the silicone. In addition, the sewing thread used in the swimming trunks, Alterfil ® T, is particularly soft against the skin and gives a nice finish at the edge.

The swimming trunks are produced in Europe under the highest OEKO-TEX standard 100 certification, which is given to products that have passed tests against harmful chemical substances.

Designed with the small details in mind

  • Ranging from 31 cm to 37 cm in side length (depending on size). These lengths were chosen after +90 tests on boys aged 3-15 years to find the optimal length where they don't go halfway up the thigh or go past the knee. This results in a length that ends slightly above the knee.
  • Equipped with a waist drawstring so you can quickly and easily tighten or loosen your swimming trunks
  • The typical sewing seams on the front are omitted, giving Surfy Eco Jammers a completely flat look from the front and avoiding unnecessary disturbance to the little guy.
  • Added a discreet white logo on one side to maintain the classic look
  • Comes in a free (value: 99 kr.) and reusable wet/dry bag (see it here) that the swimming trunks can be put in to and from training, so the rest of the swim bag doesn't get wet after the swim.

In addition to this popular model in the form of Blue Picks Blue, Surfy Eco Jammers are also available in a Orange Corner, Blue Corner, Blue Picks and Green Corner model.

Delicious bathing suits

I bought these bathing suits for my son, who is really happy with them and he thinks they are sitting really well and are good when he is swimming.

Anne S.
Good bathing suits

Super good bathing suits. They sit well close to the skin so that no air comes in and makes air bubbles under the pants as with other similar products. Sitting comfortably.
