Hyperlite 3400 Windrider Pack 55L

The 3400 Windrider has made a name for itself as the ideal Appalachian Trail thru hiking pack with its massive mesh pockets that help to dry wet gear on the move, and its adaptable carrying capacity as supplies accumulate and dwindle along the route. Ideal for weekend, section, or thru hikes where resupply points are less frequent and/or for equipment flexibility. When the extra volume is not in use, the 3400&&';;s top can roll down enough to make the overall size of the pack similar to the 2400, but that additional space can come in pretty handy when you need it.
