Military workwear purveyor maharishi is introducing a versatile day backpack for Spring/Summer 2015. What makes the pack unique is its use of High Frequency Welding to ensure utmost waterproofing and durability. Traditional accessories manufacture process uses stitching, which creates holes in the fabric that might allow water to seep through. High Frequency Welding, on the other hand, is a technique more commonly used in military, medical and emergency service applications, and joins fabric panels together by sending High-Frequency radio waves that intensely vibrate the fabric at a molecular level, causing the panels to join together. Other features include low profile shoulder straps, quick access top pocket, zipped internal mesh pocket, an internal suspended padded lap top sleeve and glass bead reflective maharishi branding to complete the look.
