+Heatwave™ Merino

A bi-component thermal fabric combining merino and polyester yarns. Superfine 18.5 micron merino wicks sweat away from your skin while the polyester provides a durable, non-pill outer. Mid weight at 170 gm/m2 and machine washable.

• Composition: 51% merino; 49% polyester

+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.

+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.

+FAQ

▸ Why are Heatwave and Lightwave Merino so comfortable next-to-skin?

• Heatwave and Lightwave combine 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.

+Heatwave™ Merino vs InfraRed™ polyester?

• Your base layer is a critical part of your clothing system in cold conditions. Its primary purpose is to move excess sweat away for your body to minimise the cooling effect of any dampness against your skin.
• Heatwave™ Merino is sensational when you're on-the-go in cold, dry conditions. It keeps you warm by absorbing and dispersing any sweat, letting it evaporate faster. However you can 'overload' the fabric with prolonged use or in wet conditions. At that point it no longer has great thermal properties. So, an excellent choice while you're moving and expending energy, but can cause you to chill out if stopped for an extended time.
• InfraRed's polyester fibres absorb almost no moisture - so the fabric dries considerably faster when you stop exercising. A moisture management treatment plus a brushed finish against your skin helps disperse sweat (but not quite as effectively as merino does). In addition the FarRed™ mineral print against your skin reduces 'far infrared' heat loss. A good choice in wet conditions and if you anticipate any faffing around on your ride, or on multi-day adventures when you need your clothing to dry overnight.
• Heatwave™ has the additional benefits of the low-odour properties of merino wool. The FarRed™ mineral print also disguises smell - but to a lesser extent in our experience.

+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 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. 

• Wash colours separately.
