I LOVE this backpack. I just ordered my second one - the first one has lasted me almost 5 years of daily use, but is starting to get some rips in one of the pockets, hence the replacement. It’s not very large, but fits everything I need for a day hike/ride. It’s also perfect for folks like me who prefer a backpack to a purse/satchel. It’s super lightweight and comfortable, and does a decent job of repelling rain. It has multiple compartments that are very handy, and I love the built in helmet holder (which works well, but can be a little loose if the backpack is empty - in that case I’d just put my helmet in the backpack instead). One thing that isn’t a downside for me but might be for some folks is that the zipper for the main compartment goes up and down only one side of the backpack (rather than the top and both sides like most backpacks). I haven’t had any problems with this, but I am careful to shift my bag onto its side when I open it so that things don’t spill. Overall, I highly recommend this product.
