I also had tried the Vertx Gamut prior to the Evade 2.0 It was bigger than I expected, but for me it was actually a pleasant surprise because of intending to use for travel. It actually holds a lot more than the Gamut and an REI Trail40, which I had currently been using. The bottle pockets are great. I also carry either a 40 or 32oz insulated bottle and have had issue with them fitting in the Gamut as well as other bags organization and water bottle pockets. The organization is what I love. So many backpacks I’ve tried do not include a lot of organization, so you need numerous added cubes and pouches to achieve. I like a combination, but prefer the built in especially for smaller items I want ready access to. Organization is another area I think the EV2 surpasses the Gamut. The Gamut has a lot of great organization, but when used it significantly decreased space in other areas, like the bottle holders. So you had to choose between using the organization or bottle pocket rather than both. The EV2 organization is designed to not interfere with the bottle holders and also doesn’t take that much away from the internal space either. Hopefully, once you use yours for a while a get it set up as you want, you will find it works as desired.
