Excellent backpack for everyday use and day trips. It looks amazing and people dig the recycled materials story (I live in California). Straps are very comfortable, it is easy to readjust the straps on the fly even when carrying uneven loads. I like the pockets arrangement, there is plenty of room for lots of stuff and I like the fact this backpack looks great both when fully loaded and when lightly loaded (it sits well and doesn't sag). The two side mess pockets for water bottles hold them secured even when running. The only issue I found was it's hard for me to pull out or place back big water bottles without switching the bag to one shoulder - however it's a minor issue for me and this product is definitely 5 stars. It is hydration pack ready (I didn't see that on the product description page facts) - there is a dedicated partition inside the main compartment with concealed port to insert a water tube out. That took care of the only caveat I had... ;-)
