This pack is perfectly designed in a suitcase style with a great fit and extra little features you only figure out once you have it!
The main pack is a great size for everything you could possibly need! I traveled for a year around nz, oz, and south east Asia and never had a problem. We also took a tent, so I carried half a tent and my partner took the other half and I still had enough room for two weeks worth of clothes and two pairs of shoes and toiletries! And I didn't fall over or over balance with the stability of the extra adjustable straps.
I'm fairly small (5"3) but found it a pleasure to carry. It's not a hiking pack but that's not why I got it! It fits perfectly in a basket above your seats in a boat, coach or bus. Another great thing is that the cover at the back which zips over the straps means that you can avoid your pack being cling film wrapped at the airport!
The day pack was a great size with plenty of different pockets for everything from your passport to wet swimming costume.
I would highly recommend this pack to anyone who wants to travel easy and conveniently! It's amazing!
