BARE have incorporated the Celliant Infrared Technology into their new Ultrawarmth Base Layers.
We saw a real difference between a 5mm glove with the technology and one without, and so we were interested to see how it worked in a base layer.
As with most base layers, the advanced stretch-breathable fabric draws moisture away from the body to create a dry zone, while moisture is dispersed over a larger surface for quick evaporation. However, where the Ultrawarmth Base Layers come into their own is through the use of that nifty Celliant Infrared Technology.
While the fabric draws the moisture away from your body, the thermo-reactive minerals that are embedded into the material capture your escaping body heat and then reflect it back at you. Having this advanced fabric covering virtually all of your body under your main undersuit and drysuit makes a massive difference to your comfort and warmth underwater. I definitely felt warmer than usual after two one-hour dives in sub-5 degrees C waters.
The Ultrawarmth Base Layers are soft and stretchy, and very comfortable next to your skin. They are not bulky at all, so you could wear these under a neoprene or trilaminate suit and benefit from that Celliant Infrared Technology.
They are so light and comfy, I even pressed them into cycling wear when I headed up into the Welsh hills for a spot of winter mountain-biking. There was a serious frost on the ground when we set off, and I was sure glad I had the BARE Base Layers on, but they actually proved to be too warm, and within 30 minutes I had to shed the bottoms, and then a short while later the top went into my rucksack too. They went back on double-quick when we completed our ride and headed into the café for a hot chocolate, though!
As we head into the colder months, I’d be checking these out as a New Year present to myself!
