just the job!

Bought these, along with the matching running leggings for my 9 year old to wear at his new running club. He was delighted with them. They look great, wash well, brilliant price... and he feels like a proper runner!

My son loves this top. Would live in it if he could!

Ordered 2 of these for my daughters and they are very happy! Great quality, slightly fuzzy inside which will keep them cosier than I expected. Accurate sizing too. They have thumb-holes, which everyone seems to love! The orange is MUCH brighter than it appears on screen (fluorescent) but that makes them even easier to spot from a distance! Unfortunately both arrived with some slight staining but as I live in Ireland, returning would be too much hassle so I'll just hope they clean up in the washing machine!

Brilliant for kids' clothing

My youngest loves dressing for Jr Park Run.

A high-tech children's jersey made out of plastic bottles

Polyester is made from oil-based chemical derivatives. The CO2 emissions of this material are significant and resources are used up in the production process. It is important to provide a solution to the environmental concerns of sports users through innovation in industrial processes, recycling and the circular economy. That's why we have chosen to make this product out of recycled polyester made from plastic bottles.
