Speed-of-light wind protection for hammering the tarmac or commuting to the coal face. This ultra-lightweight vest scrunches down to nothing. Its mesh sides let the hard work escape, and aspirant Houdinis can wriggle in and out of it while cruising at the back of the bunch. Hi-visibility limelight option keeps you in the spotlight.

▸ Tech

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

▸ 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.

▸ WhaleTail™
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 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.

Thanks For Your Review

We value your feedback. If you're stoked with your Ground Effect kit then you might like to share it (the review not the gear) with your mates. Thanks again.

    Does what it says on the tin

    Great for blocking the chill air from your core. Fleece needs a layer like this unless its the tight knit windstopper type. Size is a bit of a juggle: big enough to be 'comfortable' round the guts can leave the upper sides loose and flapping distractingly noisily. A smaller size may fix that but be hideous for any bystanders to witness. And yes, it becomes small when rolled up. The breast pocket is great for stuffing the beanie in when that has to come off.

    Really tidy, wearable and light. Fab colour. Fantastic service, guys, thank you.

    Noisy Vespa

    My new Vespa is great in all aspects, except that it is very noisy going downhill. So much so that it is not practical to wear as it makes it impossible to hear the cars or the birds. I bought size small, as I am usually a size WM in GE gear.

    My wife has owned one for several years. It Is a great fit and has worn exceptionally well. I want to look and feel as good as she does so I bought my own.

    Brought the Vespa with the view of being more visible during daytime riding and use it daily for riding to and from work. The fit for me is true and the vest is light as and the chest pocket is real handy for keys. I'm very happy with the Vespa and know it will last..
