+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 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.

      Down and dirty

      Top marks, GE, as usual. Now I'm 70+ years and 100+kgs and off the bitumen onto the gravel, the Dogma looked the goods. And it is. I don't want to wear anything else when on two wheels. The large fit is brilliant for a large boy, but like others the side pocket, while capacious, does tend to drag things to the right, not my preferred political position. Love the colour, but hoping for some variety here. Blue is my favourite.

      Sharp look.

      Have the dogma on the back of Mr 17, unfortunately no photos. Wears well rarely off his back. Surprising neat pocket at back. Has worn well for over a year. Trim neat, great bit of kit. Regards, Peter

      Great shirt nice fit even for the ladies - always hard for us girls with a non athletic physique to find clothing that fits and feels comfortable. More colours would be nice. Your gear is well made too.

      Good on and off the bike

      Smart looking for casual and cool on the bike. Zip front surprisingly convenient and looks good. Could be a little slimmer fitting, even a small is baggy on me @ 176cm 68kg.

      Stylish and functional threads

      This shirt doesn't just look good, it works well on the trail. The material is quite fine and feels cool and comfy in the heat. Having a collar is good for sun protection. I wore it to a climate change protest on a recent very hot afternoon and it dried within a few minutes of reaching the post-rally beer stop. Unzipped the front on the ride home later for extra ventilation. I got the medium after reading that it was a looser cut - my measured sizing is between M and L. That was a good call as the shirt fits well without being tight or flappy and the fabric has a good amount of stretch. The pocket is plenty big enough for a phone, though weight will pull to the shirt to the side a bit while on the bike. All up, I'm very happy with my new fave shirt and just wanting one or two more in different colours or patterns. Top marks.
