Better Never Stops

relentlessly committed to pushing the boundaries of performance sportswear

Technical weatherproof protection

Patented warp knit fabric treated with High IQ, provides a hydrophobic finish on the outside and hydrophilic finish on the inside to give enhanced water and dirt resistant properties and unrivalled breathability.


The patented warp knit fabric construction means that despite the high number of grams per metre, our specialist fabric is 50% thinner than other fabrics of similar weight making it highly breathable, lightweight and durable.

Aerofit hood

The Castore ergonomic stormhood is designed to provide ultimate protection in all weather conditions. Treble bonded brim and self locking adjusters secure tightly and provide full coverage without restricting visibility, while the microsuede lining provides additional warmth. The hood packs away and stows nicely into the crafted bonded slit.

    Love the fit I’m training for a marathon and run over 10k a day - the kit has held up well so far for the first 6 weeks. No chafing at all which is a big plus and super light compared to my other running jackets

    Great jacket but please bring out more colours! Wear all day every day and can't fault it one bit. Super comfy and lightweight whilst also withstanding the British changeable weather. Got all the pockets you need (which also stop your phone jumping about as you run) and the hood packs away. Just now need you to bring out more colours
