FlowT & Grand Baggy Rope Bags
for serious canyoneering—light, fast-draining, and tough enough for years of abuse in tight slots and big drops.
FlowT (medium and small) can be outfitted with an optional foam insert for floatation.
XLPE closed-cell foam insert is lightweight and converts your FlowT rope bag into a floating rope bag.
Fits neatly inside the bag with no zippers, Velcro, or hardware to fail.
To install Faom: Turn the bag wrong-side-out, slide the foam under the internal flaps, then flip the bag right-side-out again.

Grand Baggy (large) is built with minimal drainage, no flotation option, and a shape tailored to fully fit Hyperlite packs, making it
the go-to choice for Grand Canyon canyoneers who prioritize pack compatibility, ultra-light and streamlined design.
- Ultra 400 Fabric: Made from 70% UHMWPE and 30% polyester with a PET laminate, it’s more than 4x as abrasion-resistant as 1000D Cordura (ASTM D3884), yet about half the weight (158gsm vs 312gsm).
It doesn't absorb water, so your bag stays light even when wet.
- Tough Mesh Drainage: The same high-performance mesh used in the Smooth Sac—carefully tested and chosen for durability and fast drainage that outperforms
bags with grommets or punched holes.
- Field-Proven: Two years of testing in tight slots, big rappels, and tosses off cliffs. Even Death Valley’s dreaded rock nettle (the infamous Velcro Plant) does
not stick to the fabric.
- Optional Foam Insert (FlowT only): Add flotation when you need it.
- no zippers, snaps, or Velcro to fail. Just flip the bag inside out, slide in the foam, and flip it back.
- Reflective RibbonEasily spot your bag with a headlamp in the dark.
- Speed BeadOpen the bag quickly, even with cold or gloved hands—no cardlock pinching required.
- Removable Shoulder StrapComfortable carry without dangling tail.
- removable for gram counters.
- Top Handle Easy to carry, clip in, and cinch closed while hanging from your harness.
- Tie-In Options Use the internal top loop to tie in the bottom end of the rope, or the lower loop with pass-through hole for tying inside or outside the bag.
- Hybrid Shape Round top for easy stuffing; envelope-shaped bottom resists rolling and fits neatly in your pack.
Bonus: Each bag ships with a spare cardlock—just in
case a cliff toss takes one out.
Pricing: Yep, they’re pricey. Ultra 400 costs up to
4× more than Cordura, and skilled labor isn’t cheap.
All bag sizes are priced equally—turns out
they take the same effort to make and nearly the same amount of fabric once we
cut around the scraps.
