  • 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 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.

  • 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.

      Shindigs. Buy 'em.

      Just buy them. At $29, admittedly discounted, it's a no brainer. Just buy 'em.

      Looove my new socks

      Admittedly I haven’t biked in them yet but keeping my feet warm in the office. They stay up well. Have good elasticity. Like that they have their size stitched in on the inner band (son has same in different size). Recommend them!

      Great for commuting and winter mtb

      Wearing these for the ride to work, great to have long socks that give full calf coverage and nice "huggy" feel without being too tight. Held up well over a long day in the rain riding Whakarewarewa. These size a little larger than expected, my Ls would be an XL in other brands. Quite long in the foot and wide in the toe (my feet are a short wide UK9/US10) they did bunch a little when fully soaked (my shoes were buckets) but I only noticed that standing in the shuttle queue watching a riding buddy literally wring out their thinner cotton socks. Shed mud quickly and hosed off clean!
