Ultra-Sil Stuff Sack Set
Ultra-Sil Stuff Sack Set
Ultra-Sil 30D CORDURA · 3-Bag Modular Set · 2 Size Configs · 131–170 g · 2000 mm HH · Hypalon Pull Tabs

The Ultra-Sil Stuff Sack Set bundles three Ultra-Sil Stuff Sacks in matched size configurations for modular internal packing organization. Built from the same bluesign-approved Ultra-Sil 30D siliconized CORDURA nylon with a C0 non-PFAS DWR finish as the single-bag version, each sack carries 2000 mm hydrostatic head, double-stitched reinforced stress points, a tear-proof drawcord with Capture Cord Lock, hypalon pull tabs, and a reinforced base handle for sliding in and out of packs. The 3/5/8L set covers clothing, layers, and kitchen kit for shorter trips; the 5/8/13L set handles sleeping layers, shelter storage, and bulkier items for longer ones.

3-Bag Modular Set
Three matched-size Ultra-Sil Stuff Sacks in one bundle — covers clothing, layers, kitchen kit, and shelter storage with a single purchase instead of buying bags individually.
Two Set Configurations
3/5/8L set covers smaller items for fast-and-light trips; 5/8/13L set handles bulkier layers, sleeping kit, and shelter storage for longer trips.
Ultra-Sil 30D CORDURA Fabric
Bluesign-approved 30-denier Ultra-Sil fabric with CORDURA yarns delivers an exceptional strength-to-weight ratio and proven durability for repeated stuffing.
C0 Non-PFAS DWR Finish
Water-resistant C0 DWR (no PFAS chemicals) sheds light rain and pack condensation without relying on forever-chemical treatments.
2000 mm Hydrostatic Head
Fabric resists 2000 mm of water pressure — more than enough to handle pack condensation, brief rain exposure, and wet grass.
Tear-Proof Drawcord
Unique tear-proof drawcord throat with two super-strong Hypalon pull tabs stays strong after thousands of openings and closings.
Capture Cord Lock
Easy-to-operate drawcord with Capture Cord Lock keeps each sack cinched shut without slipping, even when stuffed full.
Reinforced Base Handle
Reinforced pull handle on the base of each bag lets you grab and pull sacks out of deep pack pockets without snagging other gear.
Double-Stitched Stress Points
Double-stitched and reinforced stress points at the seams and drawcord attachment add strength and durability over years of use.
Slippery Fabric Finish
Slippery exterior finish on each sack slides easily into tight pack cells and pulls out without snagging on the rest of your gear.

Hand wash each sack with mild soap and lukewarm water; rinse thoroughly and air dry with the drawcord open before packing away.

Do not machine wash or tumble dry — agitation and heat damage the C0 DWR finish and stress the reinforced stress points.

Re-treat the DWR periodically with a bluesign-approved spray-on restorer to keep water beading off the fabric.

Avoid prolonged direct sunlight or UV exposure when storing; the 30D Ultra-Sil face will degrade faster in direct sunlight.

Inspect the drawcord, hypalon pull tabs, and base handle on each sack before each trip; if the cord frays or a tab cracks, retire that sack from heavy-load use.

These sacks are water-resistant, not waterproof — for full submersion protection, wet conditions, or paddle sports, use a Sea to Summit Dry Bag or Lightweight Dry Bag instead.
