Size

Avoid being boiled alive when the sun turns up the volume. The Rock Lobster boasts its own theme song for company, plus a stand-up collar and long sleeves for shade on those long exposed days on the road.

▸ Features
  • Stand up collar for UV protection.
  • UPF 50+
  • Long front zip for maximum venting.
  • Long sleeves protect your forearms from both the sun and the cold (how does it know?).
  • No-elastic hem for warm weather comfort.
  • Rear security pocket coupled with elasticised pockets for on-the-go access.
  • 'Backpack-friendly' rear zip slider garage.
  • Sewn in emergency tube repair patch, because you can never be too well prepared.
  • S and XXL sizes in selected colours only.
  • Designed & made by us in Aotearoa | New Zealand.
▸ Tech

▸ 
A lightweight summer fabric packed with technology to keep you cool and dry as. The bi-component knit backs a sharp-looking polyester outer with a smooth layer of nano-charcoal polyester against your skin. Nano-charcoal disperses sweat to accelerate evaporation and is naturally anti-microbial to fight nasty smells. The fabric dries at the speed of light - great when reduced to hand washing on tour - and even performs its quick-drying magic in the wet under a rain jacket.
  • Composition: 75% polyester; 25% nano-charcoal polyester.
▸ UPF 50
HyperActive's UPF 50+ rating extends your no-burn time by 50 times over bare skin. Designs with a stand-up collar and long sleeves maximise protection from the sun's UV rays. Yank 'em up if it gets too stifling.

▸ WhaleTail™
Ground Effect tops are cut with extra length in the back... and in the sleeves too. So when you stretch out in search of the perfect downhill position, neither your shirttail or sleeves will ride-up to expose your back or wrists to the elements.

▸ 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.

▸ 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.

Great spring and summer top for the trails. Lightweight, good sun protection and cool; especially in the lighter colours.

Rock Lobster cuts the mustard!

Had my new Blue lobster for over a month and can’t stop wearing it! It lives up to the hype and I meets all my expectations and more. Even noticed that it doesn’t smell even after a sweaty time in the saddle.

Rock lobster in Queensland

Shirt is beautiful. Would wear it out to pubs if it wasn't a bike jersey. Have worn it on 80k+ rides in the sunny coast sauna and it is perfect. Highly recommended.

A Great Top

Good to find Ground Effect still in business 15 or so years since I last needed cycling gear (says a lot for their product & customer service) and also good to see some familiar product such as the Rock Lobster. I hate when other 'local' clothing companies drop a good product from their line forcing the customer to try the new thing which may or may not work. This doesn't seem to be the case with Ground Effect. Having had 3 short sleeve Rock Lobsters from ~20 years ago which had always worked well, I decided to celebrate my return to cycling with a (ahem) more appropriately sized shirt for the modern me. Long sleeves were available back in the day but seem to be the only choice now in these sun-smart days. I go along with that and given it is not quite summer yet, the added layer is nice under a GE fleece top in the morning and light & breezy as a single layer in the afternoon. The material is great at wicking sweat off the skin to where the wind can evaporate it and it should be called 'Sweat-Be-Gone'. Dries without getting smelly too! It has a nice feel and is very comfortable. The long zip is a must and is a feature that was a fundamental from the very start and is as justified today as it was when the first shirt was made. A non-negotiable feature. Congratulations on a great product!
