+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.

      My 11yo has been riding the short. Positive feedback from him. "Good shorts but could do with a zip pocket and a loop to keep the waist strap tidy"

      Great shorts

      Wow these are great shorts, sturdy, sensible size and length and seem like great value. After assessing the other kids shorts out there these look to be the winners!

      Excellent Shorts

      My son absolutely loves these shorts! The pull tie in the waist band is great for his 'skinnyness' yet they don't feel too baggy or big for him - hes 12 about 160cm and bought the KXL which should fit for a bit. Great weight and easy to dry between rides. Really recommend and will be getting more for my other son :-)

      Shred wear for the kids

      Bought two pairs for the kids. They love them! Ten and a twelve year old. Bought the 12 youth in large, and they are a large fit, so should get some good use out of them.

      These shorts were purchased for my grandson and he loves them they have been comfortable from the first time he wore them and if allowed he would wear them everywhere
