+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.


  • 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 EcostoreEarthwise 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.

      I purchased another Brand (No Good). Found Groundeffect Bandannas the best. I Purchased 4 I would have preferred the color to be Black. or Dark Blue

      Why grey?

      I love these bandanas - have been wearing them for years on almost every ride I do. However, why go to this horrible grey colour? Can we go back to the blue please?

      Hi Chris, Thanks for your feedback. Because we buy this fabric locally (for local manufacture), when we ran out of the blue fabric our choices were grey marle or grey marle! Hopefully we might get more of a selection on the next roll over. Pedal on, Ernie.

      Great for under your helmet to keep all that sweat from dripping into your eyes.

      Ground Effect Bandanna

      have only used my new Bandanna a couple of times. Summer doesn’t seem to be in action in Melbourne this year. That said it has made all the difference to stinging eyes from beading sweat running down my forehead. Love it!

      This is my 4th Bandanna over several years (so they last). Recent Bandanna is excellent quality but would prefer black or blue bands to light grey. Previous bandanna (3rd) was of inferior quality material (after a few washes ended up hard & discoloured).
