Lightweight Stuff Sack Set
3-Bag Bundle · 3/5/8L or 5/8/13L · 110–147 g
The Lightweight Stuff Sack Set bundles three organization sacks for the backcountry. Each bag in the set is sized for a different category of gear, working together to keep your kit sorted on any trip.
2000mm Hydrostatic Head
Robust, waterproof PU-coated 70D RCS-certified recycled nylon body fabric has a 2,000mm hydrostatic head — handles rain, splashes, and brief moisture exposure but is NOT a substitute for a true dry bag. Pick this when you want organization and light water resistance, not submersion protection.
Tear-Proof Drawcord + Capture Cord Lock
Unique tear-proof drawcord top with Capture Cord Lock opening is easy to use — pull the drawcord to close, the cord lock holds it tight, and the hypalon pull-tabs give you a durable grip even with cold or wet hands. No roll-top to fold, no buckle to clip, just pull and cinch.
2 Size Combos: 3/5/8L or 5/8/13L
Two size combinations: 3L/5L/8L (110 g set) for solo packing, or 5L/8L/13L (147 g set) for bigger sleeping bag + layers. Pick the combo that matches your typical trip size.
Pre-Bundled 3-Color Mix
Each set comes with three bags in three different colors (Burnt Olive / Surf the Web / Spicy Orange) for instant color-coded packing — no need to choose, no separate orders. Toss the right color in the pack and know what's in it before opening.
White Interior Coating
White interior coating on all three bags helps to shed moisture and makes finding your contents easy — the white surface bounces light around inside, making it easy to find small items in poor light, and resists moisture absorption so contents dry out faster if the sack gets damp.
Hypalon Pull-Tabs on Drawcord & Throat
Easy-to-operate opening with durable hypalon pull-tabs on drawcord and throat on all three bags — the same ultra-durable material used in whitewater rafting and military gear. Pull tabs won't fray, snap, or tear under repeated use.
Reinforced Stitching + Overlocked Edges
Reinforced stitching on all stress points and overlocked fabric edges for added strength on every bag — the stitching is concentrated where the bag takes the most load (around the drawcord throat, on the base handle, and at the seam junctions), with overlocked edges to prevent fraying.
Nylon Webbing Handle on Round Base
Sturdy, nylon webbing handle on the round base of every bag provides a secure grab point — pull the bag out of a deep pack pocket, hang it from a carabiner in the tent vestibule, or attach a shoulder strap. The round base is the right shape for cylindrical sleeping bag stuffs.
Great for Tent Storage
Yes — the durable 70D Nylon is great for tent storage, shelter storage, and other camp organization. If you carry the poles separately (e.g., under the compression straps of your pack), you can pack the tent canopy in one of these stuff sacks. (Note: pages reference the "Ultra-Sil Stuff Sack" by name for this use case — the Lightweight Stuff Sack is the current product name.)

Rinse & Dry All 3 Bags After Salt-Water or Muddy Use
After paddle sports or muddy camping trips, rinse all three stuff sacks with fresh water and let them air dry completely before storing — salt crystals and mud can degrade the PU coating over time. A quick freshwater rinse extends waterproof life dramatically.
Re-Proof PU Coating Every 1-2 Years
Re-proof the PU coating every 1-2 years with a spray-on treatment (like Nikwax TX Direct Spray-On or Granger's Performance Repel) — restores water beading on the fabric surface and extends the water-resistant lifespan. The PU coating does wear off with use.
Don't Machine Wash or Dry
Skip the washing machine and dryer — machine washing can damage the PU coating, tangle the drawcord, and stress the cord lock. Hand wash and air dry only.
Air Dry Before Long-Term Storage
After cleaning or after a trip in wet conditions, let the sacks air dry completely before storing — trapped moisture leads to mildew and odor that transfers to gear on future trips. Open the drawcords fully and hang or drape to dry.
Inspect Drawcord & Cord Lock on All 3 Bags
Before each trip, check the drawcords and Capture Cord Locks on all three bags for fraying, sticking, or weak retention — a drawcord that won't hold tension is a sack that won't stay closed in your pack. Replace the drawcord if it frays beyond a few strands.
Repair Pinholes with Gear Aid
Small pinholes in the 70D nylon can be repaired with Gear Aid Tenacious Tape patches — apply to the inside of the sack, let cure 24 hours, and the patch is more durable than the surrounding fabric. No need to replace the whole sack for a small puncture.
