Perhaps this is not the traditional type of backpack posted here, but I was thinking that someone on geartrade might be interested in a Deuter Giga Bike EL bike commuting backpack that also can do double duty as a hiking day pack.

Price: $90 shipped in USA.

This is the Extra Long version for taller folks (6 ft+). I have owned this for a few months and used it off and on, mostly for bike commuting but also for some day hikes. Condition is good, shows very few signs of wear except some light scuffs/stains on the front of the pack. No other damage. I really like this pack and its features, but selling because this is pretty large (32L) and I don't need the large capacity on most days, so looking for something a bit smaller. The side pockets will fit a Nalgene, the laptop compartment is plenty large for a water bladder, and the main compartment has plenty of space for a day's worth of gear.

Let me know if you have comments or questions. Thanks.
