Azure Blue

Protect your cranium from piercing rays and wind blown dust 'n' dirt with this item of bohemian chic dredged up from the 60's.

▸ Features
  • UPF 50+
  • HyperActive™ fabric fends off the sun without causing you to overheat.
  • Now with a stretchy cotton lycra band.
  • Flat seams for less bulk under your helmet.
  • One size only. 
  • Designed & made by us in Aotearoa | New Zealand.
▸ Tech

A lightweight summer fabric packed with technology to keep you cool and dry as. The bi-component knit backs a sharp-looking polyester outer with a smooth layer of nano-charcoal polyester against your skin. Nano-charcoal disperses sweat to accelerate evaporation and is naturally anti-microbial to fight nasty smells. The fabric dries at the speed of light - great when reduced to hand washing on tour - and even performs its quick-drying magic in the wet under a rain jacket.
  • Composition: 75% polyester; 25% nano-charcoal polyester.
▸ UPF 50
HyperActive's UPF 50+ rating extends your no-burn time by 50 times over bare skin. Designs with a stand-up collar and long sleeves maximise protection from the sun's UV rays. Yank 'em up if it gets too stifling.

▸ More than Kiwi Made
Ground Effect clothing is crafted right here in New Zealand. Has been ever since we started back in 1994. Manufacturing locally works for us. We operate a quick-response system - holding minimal stock of any one item, but churning out a few more quick-smart when the pile gets low. The upshot is that we are seldom caught with our shelves empty, so orders get despatched the same day you place them.

▸ Washing

  • All Ground Effect clothing enjoys a warm 40ºC machine wash. Try to avoid cold-water detergents and those with bleach, 'oxygen whitener' or fabric softener.
    • The cold-water varieties have little enzymes that are super-charged to brave the cold but can damage technical fabrics and cause skin irritation. 
    • Bleach rots natural fibres like merino, strips the dye, attacks laminates of waterproof fabrics and can also cause skin irritation.
    • Sodium Percarbonate (the main ingredient in oxygen whitener) can make colours run.
    • Fabric softener and stuff containing it like wool wash destroys the water repellent finish on waterproof and water resistant fabrics, and can cause colours to run. 
  • As a rule of thumb, a product that is easy on the planet is also easy on your body. Select a mild plant-based soap like EcoverEcostoreEarthwise or Aware.
  • Hand washing is sometimes the only option on tour, but a washing machine rinses more thoroughly and is preferable if you have the choice.
  • Most Ground Effect gear dries super-fast so hanging on the line or drooping over the bedpost is generally the best option. High heat can damage some fabrics so if you do take your threads for a spin, set the device on 'medium' or 'warm' rather than hot. A lap in the dryer is recommended for your rain jacket, after it has dried on the line, as it helps recharge its water repellent finish.

    I was surprised to find the Jolly Roger not only kept my follicaly deprived skull warm, reduced sweat dripping but also made wearing the helmet more comfortable big thumbs up, glad I got two

    Ordered 2. Then 4 more. Wear them every cycle day under my helmet to keep the sweat off, the sun from piercing through the helmet to my less than fully covered scalp, and keep my scalp from bathing in the residual bacteria that is in all helmet padding from the second day you wear it. Even wear them around town, on the airplane, and anytime I want to cover my head but don’t want a hat to worry about. Wash and dry quickly.

    great under a helmet

    helps keep the sweat off the helmet on hot days, and the ears warm on cool mornings . Nice thin layer, packs down when not in use.

    Have used a tube for years to protect my head from zebra stripe sunburn, but having purchased Jolly Roger I love it and use it all the time. Keeps the sun off the dome and absorbs sweat while not being too hot. Great product

    I hate the sweet running into my eyes, it pulls the sweet away , also helps to keep my head cool and stops my head from getting sunburned through the fins on my helmet
