A technical tee that delivers enduro attitude without breaking into a sweat. HyperActive fabric dries fast and the nano-charcoal layer against your skin keeps you sweet. Mix and match with your best-baggies or a pint of best-bitter.

  Regular Fit - middle-of-the-road comfort for all-purpose riding. Not too tight or too loose - just right for most cyclists in most conditions.

+HyperActive™
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.

Haywire is awesome!

I love this shirt - it looks smart, but is super practical with great performance fabric that wicks moisture - paired with my slim jims I basically can spend my whole day in them whether I'm riding, gardening, or at the pub!

Haywire Review

This T-shirt rocks! Great fit and feel, both on and off the bike. It is my go-to top for the mtb and also increasingly just as a great looking casual top.

On and off the bike

very happy with my Haywire, use it for riding to work on the odd warm day in Wellington, but it also doubles as a running top or slack around on Saturday shirt. Performance fabric does a good job of keeping you comfortable. If I could make one request I'd make it an inch longer in the body. Its more a standard t-shirt length than the overlapping draught proof fit of some GeF tops.
