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. We're making more as fast as we can. Give us a call for more information or order today to get in the queue.
A technical tee that delivers enduro attitude without breaking into a sweat. HyperActive fabric dries fast and the nano-charcoal layer against your skin keeps you sweet. Mix and match with your best-baggies or a pint of best-bitter.
Regular Fit - middle-of-the-road comfort for all-purpose riding. Not too tight or too loose - just right for most cyclists in most conditions.

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.
I love this shirt - it looks smart, but is super practical with great performance fabric that wicks moisture - paired with my slim jims I basically can spend my whole day in them whether I'm riding, gardening, or at the pub!
My 2nd Haywire, as the first one was so good decided to buy another, same awesome quality , relaxed fit , great breath ability and always washes and dries well.(my original one still looks great after 18 months)
very happy with my Haywire, use it for riding to work on the odd warm day in Wellington, but it also doubles as a running top or slack around on Saturday shirt. Performance fabric does a good job of keeping you comfortable. If I could make one request I'd make it an inch longer in the body. Its more a standard t-shirt length than the overlapping draught proof fit of some GeF tops.
Thanks for your review and comments Jack. I have passed on your feedback to the Designer. Pedal on, Ernie
