I have purchased Kelty Redwings through all of Kelty's iterations of design change. So, after flat wearing out several over the past twenty years, using them for work and play, I can't praise Kelty enough for developing a comfortable, versatile, practical, and stout pack. Plenty of room allows you to stuff more than enough gear. Mine has successfully carried 40 pounds of archeological survey equipment, food, water, foul weather clothing, etc. for hundreds of miles in the Chihuahuan desert. At the end of the day, my legs are tired but the pack rode all day like it was part of my body. Great pack - highly recommend it.
