Over 2,000 UV Days in Sydney, and Counting
We launched Crazy Arms in National Skin Cancer Action Week 2018. A lot has happened in those 8 years.
There's been a lot of hard work, a lot of fun, and it is great to see that more people than ever are "slipping" on Crazy Arms.
There have been a lot of sunny days too (more than 2000 days in Sydney where the UV index was over 3, and sun protection was required). “It’s not just about super sunny days,” says co-founder, Martin, whose 2016 BCC operation prompted the business start-up. “It’s about having simple reliable sun protection whenever you're going to be exposed for over 20 minutes.”
Sun Safe Habits for a Lifetime
Adding to earlier studies by Michael Kimlin on under-18 UV risks, recent research by QIMR Berghofer research (29 June 2026) has shown that sun exposure and potential UV damage is cumulative. Protecting our kids for the long-term was our founding motivation.
Unlike sunscreens that require frequent reapplication, Sun Sleeves offer consistent, day-long protection. Add some fun patterns, and Crazy Arms can make sun protection part of an enjoyable daily routine for kids.
Indeed, the National Skin Cancer Action Week 2026 theme this year is "sun safe habits last a lifetime" to encourage Australians to consistently use sun protection, and pass the message on.
Fun in the Sun
“We wanted to encourage this kind of 'dress up with purpose' while our kids were little” comments Design Director, Steve. “Designs like 'Unicorns', 'Aliens', and 'Mermaids' remain best sellers, and we've since added adult designs too.”
Crazy Arms soon realised it was not all about the kids. Outdoor workers, Golfers, Cyclists, Bowlers were also asking Crazy Arms for products in fun or practical colours for all sizes of arms. This year, Crazy Arms partnered with interns from the University of Delaware Fashion College on a new range of limited edition prints like "Fishies" and “Meadow” are already top sellers.
Producing with the Planet in Mind
Producing with the planet in mind is core to Crazy Arms. “Our kids wouldn’t have it any other way,” says Product Supremo, Jason. Crazy Arms uses lightweight, moisture-wicking fabric made with yarn from regenerated waste, including ghost fishing nets. Favoured by top swimwear designers, this fabric offers ARPANSA-tested UPF 50+ protection. Crazy Arms are packed and dispatched in recycled packaging.
Sales have grown each year since 2018. “It’s now a significant commercial hobby for the three of us. We’re not trying to create the next big sportswear brand” says Martin, “but hope that we can make a difference both here and across the globe”
Because UV damage is cumulative, the team will never really know if Crazy Arms saves lives, but helping people have fun in the sun doesn’t seem like such a crazy idea.
