  • 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. 

  • Wash colours separately.

    Perfect for those chilly winter rides

    Tested these out in cold weather and light rain and the wool material always works so well, they do not slip down and they act like compression tights, highly recommended.

    Best sporting socks.

    This is my second pair of Shindigs. My last pair has lasted nearly six years of mountain running and cycling. They were savaged by a gorse bush and had to be retired. Had they not suffered this injury, I have no doubt that they would have lasted another six. This new pair has the perfect amount of compression, warmth and comfort that I am familiar with and are worth EVERY dollar.

    Great socks

    Purchased these for my wife . She normally takes a women's medium size and ordered the medium size socks. I should have read the sizing chart !!!! my fault. As when the socks came they were way to big for my wife. But they fitted me perfectly and I am now the proud owner of the socks. They are great to ride in and keep my feet nice and warm. Thank you for the great product and super fast delivery ,highly recommended.

    Have bought several pairs over the years - they are warm in winter, nice and long, hardy, they breath well, and the merino wool is comfy.
