▸ 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.

▸ 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. 

  • 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.

Thanks For Your Review

We value your feedback. If you're stoked with your Ground Effect kit then you might like to share it (the review not the gear) with your mates. Thanks again.

Back in black...

After my family forced me to stop wearing my old shorts held together with duct tape, it was great to pull on a new pair of Supersonics and jump back on the bike without fear of an indecent exposure incident. The Supersonics don’t make me go as fast as Concorde, but they’ve got the right amount of padding in the right places; the seams are well positioned; and they’re close enough fitting to be comfortable rather than feeling like you’ve been shrink wrapped. Here’s to the next 5-10 years of wear. Cheers, Groud Effect - another happy returning customer.

Super Supersonics

I've tried others but have always come back to Groundeffect nicks for road riding comfort - even on century rides. I've been wearing their gear for 20 years and will continue to for as long as I can swing a leg over (my bike that is -saucy!).

Supersonics are super comfy!

I have 3 pairs of Supersonics, all are very comfortable. Have ridden them on long days in the saddle without any issues whatsoever. The only caveat is that the sizing chart tends towards the smaller size. I am a slim 6'2" and for tops, the medium size is perfect for me, but for the shorts I would go XL.

Hardtailed the Heaphy

Great pair of shorts and as a result had no problem with the fact that we had hardtails on the Heaphy track. Keep producing quality gear. Thanks
