  • Composition: 100% polyester with PU membrane.
  • 100% windproof.
  • Durable water-repellent (DWR) finish on face fabric.

+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.

  • 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.

    Absolutely a fab product (as usual from Groundeffect

    Gets a little chilly on the early morning rides and wearing snow skiing gloves and overly thick socks just doesn’t quite cut it riding the bike. I bought the Lucifer socks and Chipolatas gloves. Wow! Just the right comfort of warmth on both tootsies and fingers. Although not bulky they offer exceptional dexterity and …. did I mention comfort.? Another winner from Groundeffect

    Get warm on Heaphy Track

    Recently biked the Heaphy. First day...buckets of rain Day 2 bit of rain then sun came out. Lucifers handled both days and my feet were thankfully warm and dry. There was a bit of pushing uphill and my socks were blisters. I’m a women’s 8.5 , bought the Smalls which fit well over the first sock layer. Comfortable with or without another layer.

    The key to warm feet

    I have trouble keeping my feet warm on the sub-zero winter morning rides here in Canberra. These socks provide a thin extra layer between my socks and shoes that work better tHan overboots to keep the wind out. Combined with overboots they make a big difference in keeping my toes warm. Great product, good price, high quality!
