We are all familiar by now with Columbia’s Omni-Heat Reflective and similar technology from other brands that use titanium prints on the inside of garments to reflect your body heat back at you to help keep you warm. Rab has taken this concept one step further — instead of a print or overlay, titanium coated strands are woven directly into a fabric to not only add a level of breathability, but it also won’t wash out over time.
The make the fabric, nylon fibers are individually coated with titanium through a process of vaporizing and then condensing the element. These coated fibers are then woven into a soft-against-the-skin fabric that works to reflect your body heat back at you.
This new titanium weave fabric can be seen in the company’s Mythic Ultra line of sleeping bags for Spring 2020. Stuffed with 900-fill certified RDS (responsible down standard) down, the 32-degree Mythic 180 ($550) weighs just 400 grams. And while it is rated to 32-degrees, Rab found the titanium strands mean that the bag feels 14 degrees warmer than its official EN rating when used out in the field. The Mythic 360 ($650) is rated to 20-degrees and weighs in at just 606 grams.
Another piece of crazy light gear from Rab for next spring and summer is the Phantom rain and wind jacket. Made from Pertex Shield fabric and fully seam taped, this 2.5-layer jacket weighs just 3.1 ounces and packs down to nothing.
Needless to say both of these pieces of gear would be awesome for any bikepacking or backpacking adventure you have planned next summer.
