  • Embrace Truly Sustainable Style, with our natural fabric swimming trunks, meticulously crafted from organic cotton. We’ve used safe, non-toxic dyes for vibrant colours without harmful chemicals.
  • Outer fabric: 100% organic cotton for eco-conscious comfort.
  • Inner briefs: 98% organic cotton, 2% lycra blend for a flexible fit that maintains its shape. The lycra used is free from Pfas and BPA
  • Our organic cotton is sustainably sourced and safer for both your child’s skin and the environment. Significantly reducing microplastic exposure and pollution compared with conventional polyester or nylon trunks, which shed millions of tiny plastic particles with each wear and swim.
  • No mesh lining inside; instead, enjoy the comfort of a soft, itch-free cotton brief.
  • Each pair comes with a convenient cotton drawstring bag for all your summer adventures. 
  • Enjoy the sun safely: Our swimwear is rated UPF 50+, offering excellent UV protection for peace of mind during those sunny day adventures.

Beautifully soft boys swim trunks

I didn’t think swimming trunks could be so remarkable! The fabric, both outside and in is so soft to the touch and beautiful quality. The print is joyful and tone of green feels really considered compared with a lot of other ‘primary coloured’ kids’ clothes. My son is quite particular about how clothes feel and was delighted with these. Thank you Pure Earth Collection for another gorgeous product

Grandchildren live the swimsuits. They have worn the suits everyday since the received them

Fabulous trunks - beautiful quality & lovely design

These are really lovely! My boys are very happy with the feel of the fabric, they adore the print and colour and are thrilled that there isn’t any mesh inside! & instead, it’s a lovely organic striped fabric inside. Couldn’t recommend these highly enough!
