    ▹ 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 Ecover, Ecostore, Earthwise 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. 

    • Wash colours separately.

Great socks for a really cool morning.

I've worn these once since I go them here on the NSW north coast on a chilly morning - zero degrees. They are warm. I'll be wearing these next week when I do a three day ride up Armidale way which will be chilly. Ground Effect gear is great, I love it.

This is my second pair of lucifers as I went through the big toes on first, which was entirely my fault for not purchasing the correct size.. they are fantastic at keeping the cold out on these sub zero mornings as I still ride to work 5 days a week. Highly recommend, no need for outer shoe covers when using lucifers. Cheers Jeff

Little Lucifers

Training throughout the Taranaki winter..had to get some wind proof socks. I wasn't keen on toe covers.Ah ha, my bike buddy told me about these Lucifers. They keep the wind chill out..and we get the strong southerly winds here. They aren't bulky inside the shoes! Yahooo! Maybe I could wear one on my head too..hmmmm

* Lucifer Socks!

* Bought these as a last resort after wasting money on 'Thermal' toe caps. Riding conditions are between 0 and 3 degrees most mornings and my toes were the bits that were suffering the most, with the discomfort after 30 min or so impossible, so the bike was getting abandoned. The Lucifers were bought after hours trawling the net, and am really happy to say that that have made a massive difference and enabled rides on these winter mornings. This morning was 2' and I was able to complete 90 mins with just a bearable level of discomfort. Groundeffect - thank you for a product that does exactly what it says - keep up the good work!
