▸ Hazard!™
Night travel is a spooky experience. Many Ground Effect garments feature our Hazard!™ reflective logo and piping to help remind traffic that we're on the road too.

▸ 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.

▸ Washing

  • 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.

    Half pipes review

    Great for commuting in spring when it's a bit chilly in the morning. When it warms up just take them off and put them in your back pocket

    awesome pipes for keeping your pegs warm in the coldest of Tassie winter mornings. Easy to pull on/off with the inbuilt zips, and they stick to your legs and stay in place perfectly

    These puppies are really warm - and so much better than the typical lycra legging pull-overs I’ve used previously. Really good for those rides where there’s a bit of moisture around. They’re pretty grippy too so stay up. Good bit of kit.

    Bought these for my wife, and found them a little too long. Difficult to size without a leg length measurement, however worked well on the Timber trail.

    These pipes are smokin'

    Used these on a tour we just finished in Tasmania. We had a couple of cold mornings which don’t do my knees much good but the pipes did the trick keeping my knees warm and the pain at bay. I also used them overnight as I’m big on layering both on the ride during the day and in the tent at night. As with most merino products they have a wide thermal comfort range so I didn’t overheat when the workload increased on the infamous Tassie hills, and was able to wear them until the early afternoon before removing them.
