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.

    • Full length front zip.
    • Silver mesh sides for maximum breathability.
    • microFoil™ front and back deflects cold wind and drizzle.
    • Hi-visibility Limelight option helps you stand out in dim light.
    • Hazard!™ reflective logo at rear, and reflective piping on chest and back.
    • Zip chest pocket for cell or shades.
    • XS size option (approx. women's small).
  • ▹ 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.

    • 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 Ecover, Ecostore, Earthwise 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.

Cool Vespa sleeveless top

I thought the Vespa top was a bit of cycle that was nice to have rather than something I use a lot. I was wrong. For my commuting I use it most trips and it keeps a bit of chill off me in late spring. It is also nice and bright for others to see. Finally, it is really light and fits into a tiny space in my bag.

Great garment but sizing might be an issue

This is a great garment. I purchased it as a birthday present for my son, about to start cycling to work in Auckland traffic. He loves it, but found the size indicated by his chest measurement too small. A return and replacement was quickly and easily organised - can't beat Ground Effect for service.

Vespa size L

I can't remember what my earlier vest was called but this one is a bit snugger, but thats ok cause i wear it mainly on the road bike now. I like the pocket on the chest and it rolls up compact for stuffing in a pocket.

Good fit, handy pocket, robust zip

Has definitely made me more attractive to the opposite sex too.

A wind proof torso.

This is a great little jacket, with many pros: It packs down super tiny, fist size, so you can always take it with you. It has mesh sides which vent well hill climbing or in warmer weather. Has a full length zip for serious cool down. Nice bright colour, like a high viz vest. Keeps you dry when it's showering with rain. And only one con: it is so noisy. It flaps like a machine gun in your ear on down hills or head winds. And I live in The down hill head wind capital. The flapping comes from the shoulders so it's right by you ears. And it's so loud, I am not sure what to do myself. I have the right size because I started with M and L to check.
