+FAQ

▸ Should I wear underwear with these shorts?
Hell no. You want to have as smooth an interface as possible between your bum and the saddle. The seams on your underwear will inevitably be in the wrong place - causing rubbing and saddle sores. Also underwear is generally cotton - nice for everyday use but damp skin below is more susceptible to chaffing.

+Hitching up ya britches?
  • The challenge in fitting 3/4 length shorts and tights is the inherent tension of the fabric between your hips and knees. Even with stretch fabrics this can encourage your pants to creep down off your hips so the pad no longer fits snugly against your bum. It's more likely if you're lucky enough to have a longer-than-average femur.
  • The trick is to inch up the fabric below your knees so there is less tension along your thighs. If you are a girl, think about how you pull on your fishnet stockings. If you are a boy, think about something else.

+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 EcostoreEarthwise 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. 

  • With shorts in particular, cold-water detergents and those with bleach or fabric softner can cause 'nappy-rash' so if you're experiencing issues in that department try a warm 40ºC machine wash and a change of cleaning brew. 
  • A washing machine rinses more thoroughly and is preferable if you have the choice.
  • UV rays accelerate the decay of lycra. Our fabric is knitted so the lycra component lies on the inside of the fabric - shielding it from the sun when you're out riding. Consequently you should avoid drying these shorts inside-out. It's not a bad idea to do so occasionally as the sun does help keep the pad hygienic - although it is treated with an anti-bacterial finish anyway. But drying in this manner is a trade-off with the damage done to the Lycra.
  • It's common practice to not wear underwear with your riding shorts so you need to wash your shorts daily. And it's recommended to give your shorts an initial wash when they're new - the eXo™ pad in particular becomes less stiff after the first wash.

  • Wash colours separately.

      The Geronimos arrived promptly, and looked great but the Medium size was just too small around my legs, so hard to pull on easily. I am not usually a L size and usually fit the GE M sizing fine. The Large size was much better when it arrived, perhaps slightly big around the top of waist but good enough. I found though the front is much lower than my previous pair which I have had for over 10 ten years, and felt a but odd. A Tuesday night ride on the Port Hills in cold winds was their first outing and they performed well, nice an warm if thinner than the previous pair.

      Geronimo, geronimos!

      Having worn my gernimos on several frosty morning rides on the trails around Hanmer, I don't know how I ever did winter riding without them! Paired with knee-high SealSkinz merino socks, I am toasty warm no matter the weather. Same chamois as my summertime Innuendos so perfectly comfortable. The cuffs keep them in place. The usual GE high quality I've come to expect! Buying another pair because I like a fresh chamois each ride

      I donned my new Geronimo's in the predawn light for my early chilly commute and was immediately impressed with the fit and comfort they provided.Arriving at work an hour later I realised I was wearing my old pair!!

      Tried my Geronimos on the Paparoa trail recently and found them to be fantastic. Liner was super comfortable and the extra length leg was perfect for extra warmth and kept lower legs clean. "Love em" - ride on Ground Effect. Great product - highly recommended. Cheers Pete - Nelson.

      These replace a pair that I bought at least 10 years ago and where the elastic had started to fail. I bought the new pair as I have learned to rely on the Ground Effect quality.
