The chart is a guide only. If you fall in-between sizes, the right size for you will depend on your body shape and how loose or tight you like to wear your clothes. It's no hassle to swap an item, if your first choice is not the best fit.

Hard wearing and quick drying nylon fabric - tightly woven to deliver bulletproof durability, with some stretch for comfort. Hi-Impact Plus is slightly gruntier than the standard brew for a nudge more urban style.

Approved clobber for terrorising the city, cruising the highways or café surfing. Unfashion garments combine comfort on the bike with sharp looks for when you hit the pavement.

▸ Easy-Rider™
Stretch hip panels and Trim Tabs™ keep Ground Effect baggies hitched up. Intelligent design reduces surplus fabric for a smoother and therefore more comfortable interface between bum and saddle. There's also less risk of getting hooked up on technical trails.

▸ HighRise™
A stretch lumbar panel and HighRise™ rear overlap with your cycle top to keep you covered. No bare skin or lewd exposure.

▸ 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.

▸ Weight

▸ 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.

Purchased a set of ranchsliders recently and really pleased with them. Just as comfortable as the many pairs of GE shorts I have except longer. Enough knee protection to keep warm but not over the top. As I'm not that tall the domes on both lower legs are useful. Would thoroughly recommend but have only been using them for commuting at this point. Cheers Tony

indestructible and comfy

I still have a pair of the Gen 1 Ranchsliders, must be over 10 years old now, still going strong but getting a bit tatty for heading down town so brought a new pair. Superb - comfy on the bike, tough, and good looking. New dome set-up on the cuffs works really well

Tough and Durable!

I waited until I really had a chance to test these before reviewing my Ranchsliders! My wife and I are are on day 78 of a cross country trip here in the US. I am fair skinned and hate sunscreen. I originally brought a 2nd pair of long trousers to alternate, but sent those home when I found I much prefer the Ranchsliders! I have worn these everyday of this trip. Our trip has included paved roads, dirt and gravel roads, rail trails, you name it. These trousers take it all in stride. I find I can go a few days without washing them and they do not get smelly. They have been through countless washes though and still look brand new. They feel a bit heavy at first, but once you get used to them, you do not notice them anymore than other trousers. I have ridden in 110 degree Fahrenheit (43 C). They are hot, but what fabric would not be at that temperature? At that temp, they get soaked with sweat, but do not seem to get heavier, as they do not seem to absorb a ton of moisture. I have had two people ask me about them so far, one I am sure has ordered. The only thing I do not like are the front pockets. They are very shallow and cut oddly (at least to me). The lining tends to poke out when I first put them on. I just put my hands in and that sorts things out. They will hold an iPhone, but barely. I do not put anything in the pockets while riding, of course.

Wonderful pants

These are great to ride in. The fit isn't perfect for me (I need to lose a few kilos), however, they are incredibly comfortable even though they are a little tight around my thighs. I love Ground Effect's gear and these pants will undoubtedly last me many many years.
