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.


  • 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. 

+ 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.

      New bandana

      I’m happy with it however after having 2-3 of the blue ones over the years this one is slightly shorter and difficult to tie. Would’ve preferred a darker colour too

      Stop the drip

      I've been using an original GE Brown one for many years and wanted a black one, but may have missed that option by a decade... The grey one works great and stays put with minimal tightness. Soaks up the sweat and fits well under the helmet. Another great GE product. I agree that logo could be better placed, maybe at the end of the bandana to leave a smooth front surface.

      Hi there Michael, thanks for your review. Just to let you know that the next run of bandannas will be using a softer label. Hopefully this fixes the trouble you are having with it. Pedal on, Ernie.

      Bandanna numbers

      Bandannas were near extinction for awhile, having been discovered and poached by younger family members. Now they have left home it was time to restock. Never without one. Hat, coat, gumboots and bandanna. Serious control of sweat!

      Bloody good product. I've bought 6 of them now (they seem destined for the same place in the universe as your "other sock"), and will probably buy more. BUT they don't quite qualify for 5 stars... The latest grey and previous blue ones are a bit on the short side. And I don't even have a particularly big head. The older black ones were just right for length. I get why you put a GE label on them, but the nature (thickness) and position of it really messes with my helmet, so the first thing I do is take it off. I'd much rather help you promote your wonderful brand by proudly wearing it. Maybe a re-think is in order...

      Hi Alistair. Thanks for your feedback. Fire an email if you'd like to return the Bandanna. Pedal on, Ernie
