Gonna say things shorter. Overall good. Definitely gonna not fit in some airlines and this happened on the second of two flights I've used this on and weight sensitive airlines are going to be a struggle with this bag. Not as big as I thought it would be but that's a good thing. Doesn't seem 4 liters larger than my other backpack even putting them side by side but again that's good in my view. I have some minor grips but they don't make me hate the bag and I do like the layout it offers over other bags.
First: not as rigid as I thought. It will definitely slump over if not sufficiently filled. The level of full it takes to not get the caved in dimple on the front is more than my daily commuter carry. I know it's not a commuter bag just a statement about the rigidness.
Second: the sternum strap is too high even at the lowest I can take it.
Third and largest complaint: the luggage strap is too low in the bag causing it to hang. Doesn't sound annoying but you feel a constant drag towards the leaning direction and are constantly applying pressure to keep it straight. Also looks like a less overall clean setup which to some may not matter but for the price it does matter. Applying the sternum strap kinda worked but means I'm adjusting it every time I wear the bag or put it on my luggage which is annoying and frankly should be handled well enough by the luggages strap.
My other complaints are minor. That third one I really think you guys should do a refresh of this bag or a light tweak to the design that you ship because that was annoying having the balance of my luggage off.
