The Kelty Redwing 3100 (c.i.) makes a good large day pack if you need to carry a lot of stuff, but it doesn’t have the features or the volume for multi-day backpacking trips. I use mine mainly for leisure travel and going to the beach.
Weighing in at only 3 lbs 6oz, the Redwing provides a lot of value for under $100. The pack has internal aluminum stays which can be reshaped to fit your torso. It also has an internal hydration pocket and two side mesh pockets that will fit 32 oz. BPA-free Nalgene bottles. The hydration pocket is quite large and is big enough to fit an IBM Thinkpad laptop or a 3L platypus bladder. There is however only one hydration port on the pack which comes out between the shoulder pads and is a little awkward if you plan on using a hydration hose. Most larger backpacking packs have a left and a right side hydration port so your hose slides down from your shoulders, not over and around them.
The shoulder and hip pads are well padded and the pack has a sternum strap. The hip pads are attached to the pack using velcro and can be removed to lighten pack weight if they are not needed.
The pack has a very large main compartment and two large zippered side pockets tand are useful for gear or snacks that you want easy access to. A large back pocket is also provided that has organizational sub-pockets for your wallet, pens and pencils, or travel documents as well as a clip for securing a key chain.
The Redwing 3100 provides several other features that are unusual on packs in this price range. Compression straps are provided to reduce the volume of contents in the bottom third of the back and a daisy chain, ice axe loop, and lash tabs make is possible to use this pack in winter conditions or for easy rock climbing trips.
