+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 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. 

  • Cotton shrinks. Your shirt or tee may lose a couple of centimetres after its first wash.
  • Dry cleaning or ironing screen prints or rubber labels will cause irreparable damage. Best not too.

    Zamboni Style

    Another awesome GE product, perfect for the casual ride to local café or even wear out anytime. Super comfy and sizing is spot on.

    Zamboni should see me out.

    I have just returned from a week in sub tropical conditions in jungles of North Wales (UK) Believe me it was hot and sweaty in Bala, this has not been my experience in Wales before but climate change is throwing us some hot sticky stuff. Poor packing skills meant that I wore the Zamboni non stop for 5 days and have just retrieved it from it's first wash looking fab. If it lasts as long as the other gear that I have from GE I shouldn't need to buy another but may just becuse I like it. Any chance of swapping prime ministers?

    Get your Zamboni on!

    These shirts are outstanding, I now have three! Funky patters (my latest was covered in owls!), a great fit and discrete reflective edges to ward off the road monsters. Highly recommended!

    Andy Shallice memorial shirt

    I bought the Zamboni shirt as a memorial to Andy Shallice, a worker for social justice everywhere a cyclist, runner and hill walker, but also a wearer of the best patterned shirts available When the weather is good enough in Yorkshire I will wear it with Andy in mind.

    I bought this for my son's birthday and he loves it. Beautiful material, very well made and great attention to detail. Why the white button at the top? There must be a reason!

    Hi there, thanks for your review. The white button at the top and on the back pocket are there to match another colour on the shirt and help signal you are part of the cycle revolution. Pedal on, Ernie.
