Fast and bright for commuting to and from work or taming the tarmac as the light gets low. The Trifle weighs next to nothing and compresses into its own pocket to form a tiny package - easy to slip into your rear pocket or top pocket of your backpack.
  • Full length front zip.
  • microFoil™ front and back deflects cold wind and light drizzle.
  • Stretch fabric and slim fit blocks chilling winds without any flap.
  • Hi-visibility Agent Orange or Limelight help you stand out in dim light.
  • Hazard! reflective trim dazzles others at night.
  • Zipped hipster security pocket turns into itself to form a tidy bundle about the size of a small rodent.
  • Designed & made by us in Aotearoa | New Zealand.

  Weight: 90 gm

Gossamer-light Pertex® shell fabric weighing just 49 gsm. Tightly woven 20 denier semi-dull nylon blocks wind while a water repellent finish resists light drizzle. There is no coating for enhanced breathability. Mini ripstop weave with slight mechanical stretch ensures a performance fit.
  • Composition: 100% nylon.

Outskirts™ garments are designed specifically for women. However If you're struggling to find exactly what you need in the Outskirts™ women's range, check out our men's products for further size options. Jackets, tights and baggy tops often fit both men and women equally well.

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.

Ground Effect tops are cut with extra length in the back... and in the sleeves too. So when you stretch out in search of the perfect downhill position, neither your shirttail or sleeves will ride-up to expose your back or wrists to the elements.

+More than Kiwi Made
Ground Effect clothing is crafted right here in Aotearoa | 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.


  • 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. 

  • 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.

      A must have bit of kit

      Super lightweight yet effective against the windy Wellington weather and the colour is nice and bright for my commute.

      Trifle Review

      I recently purchased this product. Now I am a lover of all Groundeffects gear and this is no exception. However size 8 wasn't available in yellow and I purchased a size 10 which I needed to put darts in the front to make it fit around the hips. So for me this product was generous in sizing. Groundeffects clothing lasts for ever and I use mine regularly. Pam Thompson South Otago

      Spectre Shell wear

      Perfect fit and shape for my wife who loves the protection and warmth on these stunning autumn days. Excellent breathable product - fit for purpose.

      Not a mere Trifle

      The trifle has been an excellent addition to my bike wardrobe for autumn. It keeps me warm at the start of a ride then packs down small to stow in a pocket as the day and I warm up. Sizing is true and it fits snugly. Another winner from Ground Effect.
