  • 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.

      Wore these on cold mornings ( around 0degsC) on Clutha Gold and Alps to Ocean in May. Wore thin merino socks underneath and running shoes. My feet stayed warm. I don’t think they would have been enough on their own at that temperature. But worked well for me.

      Lucifer Socks

      These are one of the best purchases I've ever made. Winter riding leaves you with cold feet, I've tried two pairs of socks but they are too tight in my shoes so my feet go numb. Tried Skins, while they work to some degree they don't fit snuggly, a bit thicker so a little tight and let air in. I have found the Lucifers to be light, 99% warm, snug and fit nicely in my shoes. Even after river crossings where your feet are spongy wet my feet were cold but not the usual frozen. Would definitely recommend.

      Lucifers are Hot!

      I gave these to a friend who was upset to have lost her first pair. Having cycled through pedal-deep water and ending up with wet feet, by the end of the ride her Lucifers and her feet were dry and warm. The perfect cycling sock!

      Warm toes

      I found the Lucifer's stopped all wind chill when the temperature dropped well into the single figures early in the morning. If I was still out when things warmed up I just swapped over to the footsoldiers. Great range of socks.
