The chart is a guide only. If you fall in-between sizes, the right size for you will depend on your body shape, height and how loose or tight you like to wear your clothes. Measurements refer to your body not the garment. Jackets and baggies are sized to fit over under-layers - so you should be the same size in both. It's no hassle to swap an item, if your first choice is not the best fit.
This colour/size is temporarily out of stock. For orders placed today we'll get one to you in about a week... or consider another colour if you can't wait.
Splash through streams 'n' puddles... and sneer with derision in the face of track-splatter with these composite baggies. HydroFoil™ Plus keeps your rear dry while Hi-Impact Stretch™ delivers bulletproof durability up front. The perfect second pair of baggies in your wardrobe for when the tracks are damp and muddy.
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: 23,000mm hydrostatic head with water repellent finish on face fabric.
These baggies are supremely versatile. Add the Innuendos, Underdogs or Stowaways lycra mesh liner to deliver no-nonsense performance in the saddle. Whip ‘em out for washing or when moving into après ride mode. Winterise by using a pair of Geronimos or three-quarter length shorts as the liner.
Ground Effect clothing is crafted right here in Aotearoa | 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.
A stretch short will always deliver more performance than a baggy number as there's no surplus fabric bunched up between your bum and the saddle. However, baggies are the default choice of battle-hardened cyclists off road, on tour and around the streets. They combine a loose but not super-baggy fit with an optional mesh liner and moulded pad... providing the performance benefits of conventional stretch shorts with minimal compromise.
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 repellent 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.
I really like most things about these shorts except when I'm bent over they seem a bit short at the back - maybe I should have a got a size bigger. I would prefer two pockets as well but I did know the water resistant option came with 1 pocket!
Very good quality, not particularly breathable, seem to slide down a bit with steep seated climbs. Appear rugged. Mistakenly thought they’d have some padding. Will review further in 6/12 after a bunch more gravel rides
Great fit and comfy. They replace some super tankers that have done thousands of K’s and only the waste dome gave up in disgust.
Love how thighs get uv cover good air movement and undercarriage kept dry brill.
Plus I get colour
