▹ Man vs Wild
Merino is unrivalled for comfort as a body layer. It absorbs more moisture than synthetic fibres, mopping up excess sweat rather than letting it settle and cool on your skin. However high-aerobic activities like cycling will often overload ordinary merino. Heatwave's polyester component repels moisture to avoid total saturation of the fabric - so it dries faster to keep you toasty.
▹ Snug-as-a-Bug Fit
Heatwave™ Merino tops are intended to hug your body, ensuring the fabric sits against your skin to wick sweat away - keeping you dry and not chilling out.
▹ Hot 'n' Cold
As a single garment Heatwave™ Merino regulates your temperature through a wide range of conditions. Delivering comfort in all but the hottest climes. Yet it is versatile enough to layer under a WindFoil™, microFoil™ or HydroFoil™ shell in winter.
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.

▹ Why is Heatwave Merino so comfortable next-to-skin?
Heatwave combines the comfort, warmth and low-odour properties of merino wool with the durability of polyester. Merino wool absorbs more moisture than synthetic fibres like polyester or polypropylene. This makes it very effective in dealing with excess sweat - it is absorbed into the fabric rather than settling (and cooling) on your skin. The polyester component repels moisture which avoids total saturation of the fabric - helping it to dry faster. The strength of the polyester also maintains the shape of the garment and minimises wear 'n' tear and pilling.
The Baked Alaska, Popsicle and Hot Toddy are intended to be used as a stand alone cycle top in cool, as opposed to cold, conditions.
The Thermos, Ristretto and Submerino are all base layers - best worn directly against your skin.
The Median Strip, Berglar and Hoola are riding jerseys, with additional features including three rear pockets and long front zips. For use in both hot and cold climes and versatile enough to wear as an insulation layer in winter.
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.
Middle-of-the-road comfort for all-purpose riding. Not too tight or too loose - just right for most cyclists in most conditions.
