I'm a professional traveler in my day job and I absolutely love great bags. I use the very best I can afford; Tumi, LL Bean, TravelPro, etc. Having the right bag is an essential part of being super efficient and effective. That level thinking applies even more to backpacking and Osprey is unparalleled. I've been a backpacker since I was a Boy Scout, 25 years ago. I'm not an ultra-minimalist, but if I don't need it, I don't take it. I was carrying a Kelty bag for some time, had a North Face, and then, on a trip with my brother, he showed me his original Osprey. I fell in love with its simplicity and ease of carry as well as the customer service from Osprey. I ordered the Kestrel 38 about 4 years ago and can honestly say, I've never carried a more comfortable bag. Size your bag correctly and Osprey will carry better than any bag on the market, whether loaded down for a weekend or lightly loaded for a hike with the kids. The size is perfectly versatile; forcing you to think about your load on long weekends, and leaving plenty of room for day hikes. The long and short is that this is the best hiking back I've ever owned and based on the quality, build, and longevity; when it comes time for the next one--I'll be buying an Osprey.
