Lightweight but durable construction. First Lowe Alpine daypack I bought is still going strong after 15+ years no busted seams tears or zipper failures. The eclipse is a huge step up from the old school lowes with plenty of pockets, exterior straps and loops, water bottle pockets and takes a bladder. Best features are the raincover and especially the unique hiking pole holder system keeps them secure so you don't have to worry about them falling off or moving around on you while you climb. Also is not just a top loader the zipper runs all the way up and down the sides of the pack making access quick and easy.
