    • Great Choice for Multiple Roles!

      Carries as nicely as any messenger using the supplied shoulder strap. Tons of room (think Jansport Classic type of room). Loads more like a backpack than a messenger due to the taller size. Does great as a lumbar pack; barely feel the weight at all (my test cargo weighed in at 13 lbs). The straps on the bottom are good to hold a windbreaker type jacket, small light tarp, etc. while the front shock cord can also hold about the same. If you intend to load this out to capacity, the Mountainsmith Srappettes would be a great add on. I use this pack for both my work commute and for hiking so far; I've had a load out for a light overnighter but haven't had the weather to try it out yet (you're not taking your sleeping bag or wool blanket with this pack). I'm happy to say it's completely at home in the woods or the city.

    • Great Daypack!

      We have purchased about 10 of these Mountainsmith TLS Daypacks over the past 5 years. Without exception they have been well constructed, durable and very handy. They are all still in use. Some have been used daily for a couple of years under trying conditions throughout the world. This is the larger size 488 cu in. Highly recommend this pack.

    • AWESOME!!!!!!

      This bag is awesome! I'm a research tech and I do lots of lab and field work. I use it as my everyday "purse" and its wonderful. No issues with the zippers or the bag liner. I do have one small problem with it, and it is that there is a lot of excess strap material so it is a one size fits all, but I'm a fairly small person so I have long excess ties kind of hanging around. This is not helpful when running through wild blueberry patches to catch bugs. Other than that its great! No issues with water penetrating in the rain as well. I would buy another one its that good.
