Why a Throw Bag Belongs in Your Anchor Kit
A throw bag isn't just for tree climbing or rescue work. When you're building an anchor on a ledge or hanging belay, a throw bag lets you get a line down to the next stance without hauling a heavy rope coil. It also helps you pass branches or rock edges cleanly, saving time and reducing snags.
The Jet 250g and Jet 300g throw bags are designed with a double-layer construction that holds up to repeated use, and their streamlined shape helps them slip through tight spots where a bulky bag would hang up.
Throw Bag Options for Climbing Anchors
- Jet 250g Throw Bag: Double-layer construction gives the JET throw-bag excellent longevity. Its streamlined shape facilitates passage through tree branches. For anchor work, you need a bag that won't split after a few throws and that slides past rock edges and branches without catching.
Jet 250g Throw Bag - Jet 300g Throw Bag: Double-layer construction gives the JET throw-bag excellent longevity. Its streamlined shape facilitates passage through tree branches. The 300g version gives you a bit more heft for longer or windier pitches, while keeping the same durable build and easy-past profile.

Choosing the Right Weight for Your Anchor Line
Both the Jet 250g and Jet 300g throw bags cost the same at the catalog level, so your choice comes down to conditions. The 250g bag is lighter and easier to carry on a harness all day, and it's usually enough for a single-pitch anchor line. The 300g bag gives you a little more momentum when you're throwing through wind or across a wider ledge.
If you mostly climb single-pitch sport or trad routes with straightforward anchor stances, the 250g bag keeps your rack lighter. For multi-pitch routes where you'll be throwing repeatedly or dealing with stronger breezes, the 300g bag can make the difference between a clean toss and a frustrating re-throw.
How to Use a Throw Bag for Anchor Setup
These steps assume you're at the anchor station and need to get the rope or tag line down to the next belay ledge.
- 1. Attach the bag to your line: Clip the throw bag's carabiner or loop to the end of your rope or tag line. Make sure the connection is secure and won't unclip during the throw.
- 2. Coil the line loosely: Hold the bag in your throwing hand and flake the rope into loose coils in your other hand. Avoid tight loops that can tangle mid-air.
- 3. Aim past your target: Identify the spot where you want the bag to land. Aim a little beyond it to account for the bag's arc and any rope drag.
- 4. Use a smooth underhand or sidearm toss: A pendulum-style underhand throw gives the most control. Let the bag swing forward naturally and release when it's at the top of the arc. Avoid a hard overhand throw that can cause the bag to tumble.
- 5. Let the line run freely: After release, let the coils feed out without tension. If the bag stops short, gently pull it back and try again with a slightly stronger toss.
Recovering the Bag After the Throw
Once the bag reaches the next stance, you can retrieve it by pulling the line back up. If the bag gets stuck in a crack or behind a flake, a nut tool like the one from the same catalog can help free it. The Nut Tool's slim design fits in thin cracks, and its hook can snag webbing or cam triggers if the bag's carabiner is out of reach.
If the bag is truly wedged, try lowering it slightly and giving the line a sharp tug from a different angle before resorting to climbing down to retrieve it.
Care and Maintenance Tips
The supplied records don't include specific cleaning or storage instructions for the Jet throw bags, but general climbing-gear care applies: rinse the bag with fresh water after use in saltwater or muddy conditions, let it dry completely before storing, and inspect the fabric and stitching regularly for abrasion or cuts.
Climbing equipment is designed for climbing use only. Always check your gear before each trip and retire any piece that shows signs of damage.
