Familiarity: I've used it once or twice and have initial impressions
I just received this and only tried it out once so far. Initial impression are good. I'm an archaeologist and needed a new day pack for field jobs. The size is good and the fit is comfortable. I'm 5ft5in and 150 lbs and the sm/med fits like a dream. There is plenty of room for ALL of my gear without being bulky. I have looked for quite a while for a new pack and everytime I tried one on that could hold everything, it was big and bulky and obnoxious which is awful when working long days, every day. I like the loops for holding things (yay, tool holders!). My one complaint: Please, more pockets on the outside! I am really happy that I found a day pack with 3 decent sized separate compartments/pouches. However, for my job, it's really important to have quick access to everything in my pack and for things to stay organized. I thought this pack had a stuff pocket on the front, but after getting the bag and checking the info on BC, I was wrong, there is not even a daisy chain. Pictures and pack information from Backcountry show that there are shoulder strap pockets, but it doesn't. I'm particularly disappointed that Backcountry would state that there are shoulder strap pockets when they are not on this pack. I know companies are streamlining their bags more and more because backpackers like streamlined bags. My hope is that someday, a backpack will be made with field scientists in mind. For now, I may just void my warranty and sew on my own daisy chain and buy some bungee cord. I haven't decided yet. I don't think I will find a better pack for my needs, but there are still features I wish were on this pack and info stated by BC about pockets were big selling points.
