Summer weight arm 'coolers' take the edge off a chilly start to your ride, and let you seek shelter from the midday sun.
+ Features
  • Gripper elastic around top of arms.
  • Lycra speed stripes.
  • Designed & made by us in Aotearoa | New Zealand.

  Weight: 50 gm

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.
  • Weight: 139 gsm.
+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 Aotearoa | 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.

  • 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 Ecostore, Earthwise 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. 
+ Shipping
  • Items are generally packed and sent the same day your order is received.
  • Costs $7 by overnight courier within New Zealand.
  • NZ$7 by tracked airmail to Australia.
  • Around NZ$15-25 by tracked airmail to destinations elsewhere in the world - calculated in our shipping cart as you check out. 
    • More shipping and tax details in our FAQ.

      Totally love them

      They really do keep you cool when riding on a hot day. It is also great to not have to slather yourself in oily sun screen. I got mine caught on a branch and the fabric pulled a little, I’m not happy with that, but it is a small price for a NZ made product.

      Great product

      Bought these for my husband but got the wrong size. I know they will be great as we have had the black cold weather ones and they are great. Highly recommend them

      Does what they say on the tin

      I was initially skeptical about these but after having used them I can honestly say they work really well both keeping your arms warm in winter AND cool in summer too. Don't know why but they really do work!

      Fit Well

      I'm using them as super light arm warmers rather than sun protection and they work well. I'm 5ft 7 and 68kg and size M fits perfect.

      Allsorts Arm Warmers

      Really well made and good quality. I bought them in autumn. They are an ideal weight for cooler rides at that time of the year but feel a bit heavy as summer weight sun protection. I am a 'normal' medium male and bought medium size. I found them slightly too short for me and fairly tight around the upper arm. I should have bought large.
