"The Black Ember V4 is for sure the best travel bag I have ever used! So much thought and care were put into the design of the V4. Highly customizable and modular. Super well built with high quality materials. Most comfortable straps that I've ever worn hands down!"

"Hey! I ordered a backpack and just got it. It’s fantastic, just wanted to let someone know. I’m an architect and designer in NYC and have designed a lot of things – from installations to buildings. Love good design. Thanks and good job."

"Loving my pack. I’ve taken it as my one and only piece of luggage to London, Barcelona, Rome, San Francisco, Las Vegas and New York. This Spring, it’ll be on my back to Berlin and Moscow. Thanks for bringing a great product to the market."

"I’ve taken nothing but my backpack on multiple week long trips to Japan, Canada and Taiwan. And I’m wearing it everyday to work."

"Great experience, walking 40+ km through 2 days with it fully loaded on my back was nice, and expandable storage through pouch is really nice for gadgets (for smartphone and my RX100 and micro tripod), and then attaching my jacket rolled with the straps!"

"I just want to tell you that I love it. Great looks, good design, comfortable."

"I just wanted to reach out and praise your company on the quality and thoughtfulness that went into producing this back. I am in love with the modularity and build quality of the V4 bag. The straps are the most comfortable straps I have ever used and it blew me away that they were removable or concealed into the back!"
