Here's what Simms has to say about their waterproof (really it is) backpack:
Set sights on multiday maneuvers down the Gunnison Gorge. And navigate
pressure-washer weather en route to Skeena steelhead with the stay-dry
confidence of Simms’ bomber, fully-submersible Dry Creek™ Z Backpack.
Powered by impenetrable TPU-coated fabrics and brick-wall radio
frequency welds, these guide-tested bags blend waterproof and
lightweight performance with uncompromising durability. Considered
features include: submersible TIZIP® zipper for cavernous access to all
your gear; interior stretch-mesh storage pockets for intuitive
organization; exterior lash points and stretch cording for wet storage;
and roll-up strap retainers that annihilate line-catch points. Fully
loaded with waypoints on lock, source plush comfort from cushioned
shoulder straps and a no-sweat back panel with breathable,
water-resistant foam.
Features
- Fully waterproof welded constuction with submerisible TIZIP® zipper to give you full access ot your gear
- Interior stretch mesh storage pockets, exterior lash points and stretch cording for wet storage
- Fully cushioned shoulder straps and back panel with breathable, water-resistant foam
- Roll-up strap retainer reduces line catchers on all adjustment straps
Here's what we have to say:
Simms finally has a truly waterproof backpack that doesn't rely on a roll-top. This is a great design as far as features go for use out in the field. The zipper is the best waterproof design we know of out there and last, but not least, it's about $75 cheaper than the equivalent (almost) from Patagonia.
Great for a Steelheader's day pack, in the boat, or really good for rafts.
