Great hiking backpack

This backpack worked great for a day trip hike in the BWCA. I love the hydration resivor and feel like it kept my well hydrated because it was so easy to use. The pockets on the belt are great for quick access items. I could easily pack my lunch, snacks, extra layers, hydration, and first aid kit in there. Solid backpack, I will for sure be ordering more from this company.

Increíble travel companion

Purchased this bag for a trip to South America. I have been traveling with several different packs over time and always seem to have a major complaint about each. This pack solved most issues well. When wearing two packs, it wears well on your chest. The straps are small and yet padded well. I can fill it with things, hike for ten hours and because of the hip straps my shoulders are not completely worn out. Most packs of this size do not offer the hip straps. Also the bungee on the back is perfect for stuffing a puffy jacket. It fits all the essentials for a long day out. The ventilation on the back is pretty good, and is stiff enough to transfer load to hips. Overall have really liked it.
