The size is okay , as it turns out. There is a pouch on the shoulder strap that would be perfect for a phone, but it is too small for my Samsung T404<a data-hook="product-link-linked" class="a-link-normal" href="/Samsung-T404G-Prepaid-Phone-Net10/dp/B0053GQO1U/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Samsung T404G Prepaid Phone (Net10)</a>&nbsp;which is smaller than most smart phones. I wanted a simpler bag than I had, as it was floppy and stuff got lost in it. This is an improvement in those directions. The color is neutral and pleasant, and the strap is oriented well. I can wear on one shoulder, or loop it over my head, cross body fashion. I usually carry vitamins and supplements, some earplugs&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Etymotic-Research-ER20-High-Fidelity-Earplugs-White-with-Clear-Stem/dp/B0015WNZ9K/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Etymotic Research ER20 High-Fidelity Earplugs-White with Clear Stem</a>&nbsp;an iPod(which it has a special weatherproof earphone port for), work gloves, poop bags for my dog, maybe some water and a sweatshirt or thin jacket. I keep losing and/or dropping my phone, so I had hoped for a built in pocket for that. In the future I might be carrying a netbook, which would easily fit,  probably a smallish laptop would fit. I'll likely add something on the shoulder strap for the phone. I DO like the un-complicated exterior, and the bag holds its shape without being overly stiff. The bag has taped internal seams, and is constructed durably. The part that goes against my back is lightly padded.

Update: 7-9-2013:
On further use,I have found that the strap slips down my shoulder easily. If it had some grippy rubber stuff on the strap that might prevent it doing so.
