Tried and Tested: 37.5 Technology

Posted on 16 July, 2018

In June 2018, 36 of our staff from Castle Donington and Long Eaton took on the Lyke Wake Walk challenge. The Lyke Wake Walk is a 40 mile hike across Yorkshire moorland, it must be completed in under 24 hours, and the going is tough and unforgiving.

The 28th June dawned on our team of walkers and the Met Office put out a weather warning for extreme heat in excess of 30 degrees Celsius. It was one of the hottest days of the year and our team certainly felt it… With the exception of Fabric Technical Assistant Paul who completed the walk wearing a 37.5 suit, complete with shirt, trouser, socks, tie, blazer and cap!

“Working in the technical team we see a lot of fabric innovations we love to try before offering them to our clients. After seeing an article in the Dimensions magazine about a man running a marathon in 37.5 fabric, I thought that hiking 40 miles in a 37.5 suit in both the freezing cold and blistering hot would be the perfect opportunity to put the fabric to the test ourselves.”

37.5 has had a lot of publicity and in 2017 Felix Mayerhoefer ran the Hamburg marathon wearing a 37.5 suit, and set a new Guinness world record! Tests have shown that when athletes are wearing 37.5 garments their performance is improved by 26%. Despite these impressive findings Paul was still a little sceptical.

Paul explains, “In all honesty I was probably the most sceptical out of the team. I’d said beforehand I was getting a little concerned, so just in case I also packed a shorts and t shirt! I was aware that it’s not a magic fabric, so if I got too hot I wanted to have other options but luckily I didn’t need them. As daft as it sounds I could have gone further… Don’t test me on that though!”

37.5 Technology is cutting edge, designed to be responsive to the wearer, cooling when it’s hot and warming when it’s cold. The temperature of the Lyke Wake Walk fluctuated between 8 degrees at the coldest point in the night, to 31 degrees at the hottest part of the day. With no shelter up on the moor, the walkers certainly felt the wrath of the elements.

Paul said; “During the night part of the walk, the temperature was low and my colleagues were wearing jumpers, scarves and snoods. I didn’t need to wear anything else, my suit kept me at a nice temperature. In the heat the suit wicked moisture away from my body and left me feeling cool, I don’t think I would have been any cooler in shorts and a t-shirt.”

Currently we have bespoke 37.5 uniforms being trialled by a leading UK bank, and two international travel and transport companies. An impressive feature of the fabric is that recovery time is sped up after a period of exhaustion and Paul was pleasantly surprised by these findings and remarked that he was keen to get going after rest breaks and didn’t feel as exhausted as he expected.

In fact, Paul was one of the first back and completed the walk in the amazing time of 16 hours and 15 minutes and was delighted to find out he won the much coveted “Best Dressed” award too!

“In short, I really do think that 37.5 Technology really lives up to its claim. This is really exciting for my team especially as we are always looking for the next innovation in fabric. I honestly wouldn’t hesitate in recommending a client to use 37.5 Technology for a reactive workwear.”
