Featuring numerous details such as Cordura ballistic nylon fabric, waterproof reversed YKK zippers, 3Xdry coating, and heavy duty construction this bag aims to please even the most discerning consumer. I for one, applaud the use of some very nice tech specs that provide some real world useful application such as the waterproofing and ballistic fabric. The bag might be a little large for some day to day trekkers but if you've ever carried around more than a laptop, filling up 40L actually doesn't seem that difficult. Available in two colorways from BEAMS Japan. More photos of the bag in the full post.
