+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 repellant finish.

+ Shipping
  • Items are generally packed and sent the same day your order is received.
  • Costs $9 by overnight courier within New Zealand.
  • NZ$12 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.

      i lost my old GE bandanna somewhere between the bike shed and the washing machine so bought a new one. the colours changed and so has the fabric and i think its got a bit shorter but bang for buck its the best value sweat stopper out there. does the job perfectly. my only complaint, the postage cost more than the bandanna.

      I use my "bandana" to slurp up my hard earned sweat while on my bike rides, using the knot of my choice. When I get home, I wring it out and hang it over a line to dry.Sometimes I rinse it out with water and then let it dry.


      Replacing lost ones

      Have been using these for a couple of years. Down to one, which is not enough: life is too short to put a wet, sweaty headband back on, I deserve the luxury of a dry one. So I'm getting 3 more...

      The bandanna is great for commuting in windy Wellington. A simple yet effective solution to keep the wind out of your ears and the sweat out of your eyes. I just got two new bandanas and I'm making good use out of them.

      Great news

      The ground effect bandanna is one off the best bits of kit I have,being a sweater and needing to wear seeing glasses having something to keep my face clear of sweat is important and this does. I've not found anything better or even close to it. I now have 4 . A great bit of kit you'll love it
