We are back from Copenhagen where we spent Christmas and New Years. I used this pack daily for 10 days and carried each day a large bottle of water in each side plus what ever else I needed for the day. I didn’t take off the pack at all for at least 8 hours each… day. You can see that I was bundled up with 5 layers of clothing because the temp was about 25F with the wind chill running about 17F. I could sit easily without removing the pack. I was amazed at the ease of carrying a moderate “load” one would expect to have on vacation. I can assure you that you will never have a customer any happier with your product than I am. It was wonderful not to have to take a day pack off every time I sat down. We rode city busses, subways and commuter trains hundreds of times and it was great to have the comfort and luxury of leaving the BackTpack on. Thanks again for a great product. Bravo BackTpack.
