I’m selling my vintage Sierra Design Flex Capacitor 25-40.  It has been used on a few day hikes. It has no tears, holes, rips, blemishes and is in near perfect condition. I just don’t use it enough to justify its space in the gear closet and I know someone will want this piece of backpacking history.

 

Currently this pack retails for $113 to $199.   I’m asking for $75 (incl. shipping within the continental US). PayPal

 

Sierra Designs’ description:

 

“Meet the versatile pack that hauls it all. The Flex Capacitor 25-40 is a beast of a backpack, constructed from durable nylon for rough conditions in the backwoods or backcountry and built with adjustability in mind. Loosen the expanding horizontal gussets for an additional 15-20 L of cargo capacity on longer backpacking trips, or cinch it tight for smaller, compact loads on fast summit days. Plus, ample quick-stash solutions on the straps, sides and bucket lid ensure there are plenty of places to store your mid-trail essentials. However you pack it, the Y-Flex suspension adds support so this lightweight backpack can hit well above its weight class.
