I purchased this pack in the spring to use for day hiking and daily commuting via Bicycle. The pack is very well made I as I have come to expect of Osprey products. I am a larger guy but find the pack to be very comfortable. The air mesh along the back does a great job of keeping you cool and keeping air flow up. The water storage is great and easy to access for refill. Capable of carrying plenty of water for day hikes. Although a little heavier/bulky than my Atmos pack, I see no reason you couldn't do a longer hike, shorter section hike with this pack. The only complaint I have is the bite valve snapped off the first week I had it. I replaced it with a Camelback bite valve as my local retailer carried no spare parts for Osprey Hydration bladders. I prefer the Camelback bite valve to the Osprey version anyway.
