COMPREHENSIVE LAB TESTS PROVE LAYERING UP WON’T IMPEDE SWINGS
Tests described as ‘the most vigorous ever conducted on garments in the history of the golf industry’ have validated a longstanding Galvin Green pledge – that wearing multi-layers of its lightweight and breathable golf clothing in the most trying conditions will not impede the swing.
THE GOLF LAB FACILITY in Toronto analysed more than 300,000 data points collected from the full swings of ten accomplished golfers and found that rotation degradation amounted to just 1.14 degrees across the entire sample set, while club head speed was slowed by less than 1 mph!
“Both the accomplished players who took part and staff who devised the tests were amazed by the lack of restriction in the swing, as they’d anticipated at least 4-5 degrees of degradation and much slower club head speeds,” said award-winning coach and club fitter Liam Mucklow, who founded The Golf Lab in 2009.
“They simply couldn’t believe it when they’d hit driver wearing all three-layers and still their club head speed stayed the same. I’ve never heard of a garment company that uses objective technology to perform human-based trials to evaluate the degree to which a garment changes the golfer’s swing – but Galvin Green deserves credit for its no compromise approach and that’s coming from someone who hated wearing outerwear during my professional golf career,” he added.
The golfers, including scratch Canadian PGA and category-1 players, were asked to hit balls with their regular driver for two hours wearing three layers of complementary tops - a VENTIL8™ PLUS shirt, an Interface-1™ hybrid jacket and finally a GORE-TEX® waterproof jacket with C-KNIT™ stretch fabric, like the one being worn by Team Europe at the forthcoming Ryder Cup matches.
Focusing on the impact on club head speed from 10 full swings as each garment was added, an optical tracking system using eight cameras captured a 3D motion at 2,400 images per second, while body sensors calibrated to two-tenths of a millimetre made it possible to accurately measure ribcage rotations as the golfers generated club head speeds around 100mph (160.9 kph).
“Less than two degrees of degradation is really an insignificant amount of loss, given the general perception of what adding two more layers could mean in terms of swing restriction,” said Carson Hau, the Golf Lab’s Director of Technology, who ran the tests and usually measures speed impressions on club shafts.
“We put the Galvin garments through the most vigorous testing ever conducted in the golf industry and the precise data we gained showed there was hardly any ribcage rotation degradation.” he added.
Some players actually rotated more when wearing all three garments, with an average loss of just 0.22mph (0.35kph) of club head speed as they automatically turned their shoulders more to generate additional power. “One player said he would now be pleased to play golf in a Galvin Green rain jacket all year round, because he actually gained more distance with his greater rotation,” said Carson.
But how do the modern stretch fabric garments compare with those of the past? When a five-year-old Galvin Green rain jacket replaced the latest C-KNIT™ jacket in the test, there was a loss of 3.5mph (5.6kph) in club head speed, which equates to about 10 yards of distance off the tee.
“We’re delighted with these results and how they validate our belief that Galvin Green garments when worn together help serious golfers perform at their best,” said CEO Christian Nilsson. “The comparison with the older rain jacket also shows just why existing Galvin users should look to update their rain gear to keep up with the new lightweight stretch fabric technology that we’ve been able to introduce in recent years.”
