Osprey is known for good packs, and I was surprised at the price point on this one, as they are also known for pricey packs. I thought maybe cuts were made, but if they were, I don't see them. This is a bit of a "hybrid" pack, small enough for as a day pack or a commuter pack, but featuring a semi-rigid back panel and hip belt like serious camping pack. Speaking of back panels, if you have never experienced the AirScape, you owe it to yourself. Especially on a smaller pack like this, it really really lets your back get airflow better than anything else I have worn. As for material, this is definitely not super rugged dyneema or anything, and it probably snags a bit more than I like if you are bushwhacking, but it's light and otherwise durable. The pocket layout seems well thought out, and the hip belt pockets are extra large (my 60L doesn't fit as much). The helmet hanger thingy only works if you have a ventilated style bike helmet, and it's not the most secure thing, I would personally have just preferred more webbing for versatility and security. That's all very nitpicky, but needs to be said if you envision this as the perfect bike bag. My other gripe is my biggest but also very specific. I got this in extended fit for a larger woman. I don't mean heavy (I understand that is demo that is often neglected in outdoor gear and I am glad to see it being available), but large, like Wagner opera valkeryie large. She's over six foot and is the sort of gal that can firemen's carry most firemen. The added length in the waist is there and is great. But the info on extended fit also mentioned for longer torsos as well, but the size chart and her experience did not reflect that. It just ends up being a bit more snug on the shoulders and looks a bit tiny. If it were a backpacking pack and I was genuinely putting enough load in it for the lifters to matter and want more weight distribution adjustment, it would be a deal breaker. But as is, she can rock it and it emphasizes her giantess nature in nature.
