I have an upcoming 10 day trip to Tuscany and am looking to get a backpack that can accommodate my modest gear (Canon digital Rebel, 18-55, Sigma 55-200, a few filters) in addition to my Macbook 13" and random things like water bottle, snacks, a book... odds and ends.I do have my tripod as well, but have come accustomed to "hinging" it to the strap of my Tamrac Tek 4372. I love this little pack for wandering around the city and short hikes, but it only accommodates the camera gear strictly. I have been researching the Tamrac Adventure 9 5549 and 3380 Aero 80 all morning and am having a hard time choosing. I am not opposed to other brands/models, these just seem to fit my needs the best. I need the laptop option as this bag will be my carry on and its just easier to combine camera and laptop. Seeing as I am a woman and traveling in late May/early June I am hoping someone can tell me if one of these will work for me in terms of comfort as I am 5'8" and will likely be in tank tops and the like. Will either of these be very warm/causing excessive sweat? Too bulky? Im not planning to bring the Tek, but if it fits I wouldnt mind. Any insight would be greatly appreciated.
