Is this bag actually waterproof?

Yes. The bag is made from Dyneema Composite Fabric 1.3 with fully taped seams, so water won't get in through the material or stitching. The roll-top closure with side-release buckles seals the opening when closed properly, keeping contents dry during rain or creek crossings.

How do you use the rock bag?

Fill the rock bag with a fist-sized stone you find at your campsite, tie your throw line to it, and toss it over a high tree branch. Once the line is over the branch, attach your food bag to the line with the included carabiner and hoist it out of reach. The rock bag makes it much easier to get line over a branch compared to tying line directly to a rock or throwing by hand.

Which size should I choose?

The 10L size works for day hikes or overnight trips with minimal food, while the 15L size accommodates multi-day expeditions or larger groups. Consider how much food and trash you need to store—bear bags should hold all scented items including toiletries, so err on the larger side if you're uncertain.

Can I use this for something other than a bear hang?

Yes. The waterproof construction and roll-top closure make it suitable for storing any gear you want to keep dry—electronics, first aid supplies, dry clothes—whether you hang it or not. The taped seams and durable fabric hold up to rough use beyond just food storage.

Why it's on GiftsFeed

Complete backcountry food storage with hanging hardware included

Most food bags sold separately from hanging hardware leave you improvising with paracord that stretches, carabiners heavier than they need to be, and no good way to throw line over a branch without twenty attempts. This kit pairs a waterproof bag with a purpose-built rock bag and a choice of low-friction or abrasion-resistant line designed specifically for bear hangs. The result is a system that works the first time you use it and keeps working trip after trip, rather than a collection of compromises you cobble together from the hardware aisle.

Good gift when

Backpackers camping in areas where bear hangs are required or recommended
Anyone who's struggled with improvised food storage systems in the backcountry
People who want a complete solution without sourcing components separately

Skip it if Requires trees with branches high and strong enough for a bear hang, so it won't work in alpine zones or desert campsites without suitable anchor points

The details

Hanging your food in bear country means you need a bag that seals tight, a way to throw line over a high branch, and hardware that won't let you down at dusk. This kit bundles all three.

The roll-top bag uses Dyneema Composite Fabric 1.3 with fully taped seams, so rain and creek crossings won't ruin dinner. Magnets inside the roll-top hold the closure in place while you fasten the side-release buckles, and a stiffener keeps the opening rigid when you're loading or retrieving food. Choose between 10L and 15L depending on trip length and group size.

The rock bag simplifies the hardest part of a bear hang: getting line over a branch twenty feet up. Fill it with a fist-sized stone, tie on your line, and toss. Once the line is over the branch, clip the included mini carabiner to the bag and hoist everything out of reach.

You pick one of two throw lines. Lawson Ultraglide Bear Line is uncoated Dyneema SK75 that slides over bark with minimal friction, and a 3M reflective tracer woven into the line catches your headlamp beam when you're taking the hang down after dark. Samson Zing-It! has a Samthane urethane coating that resists abrasion and stretches almost none, so it throws cleanly and holds position. Both lines measure 50 feet and handle the pull of a loaded food bag without fuss.

Everything packs small and weighs little enough that you won't begrudge carrying it on day hikes where a bear hang is overkill but peace of mind is worth the ounces. For multi-day trips, the waterproof construction means you can stash trash inside without worrying about leakage, and the taped seams hold up to repeated stuffing and hoisting.

Questions

What's the difference between the two line options?: Lawson Ultraglide Bear Line is uncoated Dyneema SK75 that glides smoothly over bark with minimal friction and includes a 3M reflective tracer for visibility at night. Samson Zing-It! has a Samthane urethane coating that resists abrasion and near-zero stretch, which makes it durable against rough bark and easier to throw cleanly. Both are 50 feet long and strong enough for a loaded food bag.
