+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 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: 23,000 mm hydrostatic head with water repellent finish on face fabric.
  • Breathability: 33,000 gm per sqm per 24hrs.

+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 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 repellant 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 at least a couple of times a year - certainly after a muddy mission, an especially sweaty ride, or say half 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.
  • When the fabric starts 'wetting out', it's time to apply some love. 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.
  • 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 water repellent finish 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.

      Monsoons review

      I have just completed a winter trip around the K500 loop in Kahurangi and used my monsoons. The monsoons performed really well. They fit well and we’re easy enough to pull over my cycling shoes. I only had a couple of hours of light rain and the monsoons wete waterproof enough. I would like to see how they go with a full on day of rain. I only gave it 4 stars because I would like to see how this monsoons performs over a 2-3 year (and beyond) time period.

      I typically size around 10-12 and got the 14 which are generous around the leg for layers. I wanted them like that so I could use them for commuting. The waistband is seems to fit well over layers but is a bit on the smaller side. Maybe fully elastic rather than partially elastic on the next model?. Very lightweight and packs down well. Material seems pretty durable. Have only used them a handful of times and so far happy with the product overall.

      Commuting Necessity

      These are lightweight and comfy. I got the size based on my riding shorts and I find them a bit snug around my waist but that could be the higher fit.

      Monsoon Rain Pants

      The Monsoon rain pants are the best I have ever owned! I wore them in a 12 hour adventure race recently and they kept me dry the whole time. Love the tapered legs so you can ride with them - but also that they zip open to go over shoes if needed. They are also really good to paddle in..

      Women’s or not

      Would usually buy a 12 or WS but after reading reviews purchased 14. The articulated knee is way down my calf! Much too long. The waist is firm, with “male” fastenings! Maybe they were mislabeled. Do keep you dry but wish the fit was more for women.
