+Tech

+HydroFoil™
Specifically developed for high aerobic activities, HydroFoil™ Plus combines a lightweight ripstop nylon shell with a composite membrane that is completely waterproof, totally windproof and extremely breathable. The outer fabric is the latest new-generation Pertex® Shield+ membrane. It is more than twice as breathable as most other quality waterproof-breathable fabrics, and has a small amount of stretch allowing a closer fit. The outer fabric is treated with a durable water repellent finish that encourages rain to bead up and roll off, while there is a lightweight tricot mesh on the inside for greater durability and improved moisture dispersion.
  • Composition: 100% nylon with PU laminate.
  • Waterproofness: 23,000mm hydrostatic head with durable water-repellent finish on face fabric.
  • Breathability: 33,000gm per sq.m per 24hr.

+FAQ

+Benefits of 3/4 vs full-length over trou?
We've extensively tested both full-length and 3/4 waterproof pants over the years. In our experience 3/4's provide the best trade-off between functionality and performance in most conditions - especially for mountain biking, bikepacking and touring.
  • They are easy to whip on and off over your shoes.
  • Repel rain from the most exposed areas - your bum and thighs.
  • Avoid 'chain suck' at your ankles.
  • Minimise overheating when pedalling hard.

However full-length over trou are sometimes best - notably for commuting when you want to keep your long pants dry, or when touring to really cold and/or wet places.

+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. 

  • Wash with any of the plant-based products listed above. You can also use a specific sport wash like Grangers Extreme Cleaner, Nikwax Tech Wash or Atsko 'Sport Wash'. Around NZ$30 from most outdoor shops. Any stubborn stains should be dabbed not rubbed clean. For grease spots you can use a degreaser like Swarfega. It's aggressive stuff though so take care - it might be best left alone as added character.
  • Keep it clean, but don’t wash too often. General wear along with washing progressively removes the water repellent treatment from the outside the fabric. This treatment helps rain to bead and run off - and enhances the overall performance of the fabric. Dirt, body oil, sunscreen and sweat also attack the water repellent treatment and can cause the waterproof-breathable membrane to delaminate. Wash frequency depends on how often and how hard you use your garment. We suggest washing after a particularly grubby ride or after say a dozen sessions in the rain. Use your judgement - if the garment looks dirty, the fabric is 'wetting out’ too quickly, or feels clammy then it's probably time for a clean.
  • You can help restore the water repellent treatment after washing by line-drying your jacket, then chucking it in the dryer using a warm (not hot) cycle. This 'recharges' the treatment so it lasts a bit longer. When this trick no longer does its magic you can beef up the original treatment to some extent with a product like Nikwax TX Direct - $39 from Ground Effect. A bottle is good for two or three rounds with your jacket. The effectiveness of this process depends on the age and condition of your jacket. Expect ok results if the fabric is only 'wetting out' in patches (the 'mid-life' crisis). If the entire jacket is 'wetting-out' rapidly in light rain then it already has one-foot-in-the-grave and beading is unlikely to improve much from the treatment, the money may be better put towards a new jacket. Note that while the fabric's wetting-out impairs performance, particularly breathability, the HydroFoil laminate should still be waterproof.
  • Always ensure your HydroFoil garment is completely dry before storing. Putting it away damp can destroy both the DWR and the waterproof coating. Hanging on a hook or coat hanger is best. Take care of your gear and it will take care of you.

      Good looking essential item.

      Have not worn these yet, waiting for a wet winters day however good fit and nice length and comfortable fabric. Would have liked slightly more room round the waist. I purchased WXL. Perhaps you could consider adding a gusset at waistline with a couple of domes or Velcro for us larger lasses with expanded waists.

      Best shopping experience

      It’s when things go wrong and how they are fixed that is the measure of a great company and these guys get a+++ for couriering replacement Monsoon pants to arrive within 24 hours when our first two pair got delivered to wharf road west Auckland instead of wharf road Waiheke - and they checked our measurements and sent different sizes than original order which turned out perfect. Thanks for great service.

      Do the job and then some

      Perfect. Bought for my wife to help keep her nice and dry on the daily commute to work. Did what they said on the label - good fit, easy to get on and off. Then, surprise surprise, they did excellent double duty on a snowy day across the tops on the Kepler Track.
