+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.

  • 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.

    Lucifer Socks from Groundeffect

    Bought these by mistake in that I thought I was getting boot covers. But glad I made the mistake, Really warm and useful when I am out on the tractor on cold frosty or wet days.

    This product is satisfactory between about 2 and 8 degrees. Once temp gets into negative my toes still go numb. Service and delivery no problem

    Do the job

    I got these as my riding shoes let a lot of air in. I found that after a decent ride my toes were numb. The Lucifers have fixed this issue.

    Toasty toasty

    Got these to keep my toes warm during my winter commute and am very pleased indeed. The San Francisco East Bay winter may not be as cold as some places, but days can be damp, cold, and windy. These socks, in combination with my usual shoe covers, are quite effective. My previously popsicle toes are now toasty toasty. I’ll be ordering a few more pair.

    Good quality but didn’t keep my toes warm

    Bought these after reading the reviews as I get cold toes on the chilly mornings on my daily (40 min each way) commute during the winter. The quality is good and the wind blocking fabric has meant the top of my feet are definitely warmer but the seam sits across my toes so they haven’t had the effect I’d hoped for and my toes are still as cold as they are without the Lucifers. I’ve paired them with Footsolders and thicker Zigzags with the same outcome. If the Windfoil fabric was extended to wrap around under the toes I think they would have been perfect, so my rating reflects that they didn’t solve the problem I purchased them for. As I said above the quality is good. My feet are UK11, Euro 46, I purchased Large size and they fit ok (albeit with the seam across, not under, my toes). Can’t win them all I guess.
