+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.

+ Washing
  • 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.

      Best cycling jacket I’ve ever bought

      Bought this to partner with a Berglar top for chilly cycling in Tasmania, and it has been a revelation. Brilliant for warding off a chilly Tasmanian morning and maintaining some warmth on long weekend rides, even in light rain. My only smallest of small issues is that due to its super light material the sleeves can flap a bit in the wind, but still a 4.99 out of 5 for me.

      Perfect fit and design

      Absolutely love this lightweight windbreaker! Feather light and easy stuffed into a jersey pocket, but surprisingly warm. Great for misty, windy, and chilly rides when the Anti-cyclone is too much. Got the nice orange for visibility. Not quite as swift as when I was in Welli, but shipping to the US was much faster than expected!

      Ticks the boxes

      Reflective, shower-proof, comfortable. Packs away small enough to keep in the pannier I have permanently on the bike. Bought a second bike, second panniers and so, a second Afterburner.

      5 stars for this one. Comfy, warm and very dry. Put it through it's paces riding over Arthur's Pass and it performed amazingly.

      Agent Orange /black is very stylish & highly visible. Slim fit aerodynamic & protective Ordering a size up worked out fine. Is very light and easily fits in a pocket. I am very pleased with this top.
