 Enduro-verve coupled with hot-weather performance for clocking laps at the bike park or sweating out a liaison stage. HyperActive fabric dries fast and the nano-charcoal layer against your skin keeps you sweet.

▸ Features
  • UPF 50+ HyperActive fabric.
  • Designed & made by us in Aotearoa | New Zealand.
▸ Tech

A lightweight summer fabric packed with technology to keep you cool and dry as. The bi-component knit backs a sharp-looking polyester outer with a smooth layer of nano-charcoal polyester against your skin. Nano-charcoal disperses sweat to accelerate evaporation and is naturally anti-microbial to fight nasty smells. The fabric dries at the speed of light - great when reduced to hand washing on tour - and even performs its quick-drying magic in the wet under a rain jacket.
  • Composition: 75% polyester; 25% nano-charcoal polyester.
▸ UPF 50
HyperActive's UPF 50+ rating extends your no-burn time by 50 times over bare skin. Designs with a stand-up collar and long sleeves maximise protection from the sun's UV rays. Yank 'em up if it gets too stifling.

▸ 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.

    This tee shirt fitted great. It was true to size. Unfortunately I sent it back as I just wasn’t happy with the colour for road riding.

    Great fit. Great colours. Great fabric. Bright enough to be seen, subdued enough to visit the café. Would buy again but not the black one, not bright enough on the bike. Thanks for a great item.

    Jellybean top

    Have worn this a couple of times now, really happy (especially as it was on sale ) Very comfortable in a hot Queensland summer. Fits well and is not clingy.

    Jelly bean top

    Have just given my jelly bean top it's first tour. I was a bit worried I wouldn't like it as I hate cycling in anything with sleeves, usually finding it too hot and bothersome, preferring the cool air on as much of my skin as possible. But, my sleeveless top was worn out and there wasn't a new design to replace it. I found the jellybean top very easy and comfortable and not the least bit clingy or sticky, even in hot and humid temperatures. And it was good to have my upper arms covered and not having to lather sunscreen on them. It also dried very quickly so could be washed overnight and put back on in the morning. I'm not sure whether I could have gotten a smaller size but it was nice being loose and non restrictive. Great colour, would love it in just your beautiful blue.
