Sea to Summit Lightweight Recycled Nylon Stuff Sack

The Sea to Summit Lightweight Stuff Sack is a six-size modular packing sack built from bluesign APPROVED, RCS-certified recycled 70D nylon with a PU inner coating rated to a 2,000mm hydrostatic head. A non-PFAS DWR finish on the outer face sheds light moisture, while the white interior coating makes locating gear fast in low light. Sizes run from 3L to 30L, available in Burnt Olive, Spicy Orange, and Surf the Web depending on size.

Organized Packing Without the Weight Penalty

Modular packing works only when the sacks themselves don't eat into your weight budget. The Lightweight Stuff Sack's recycled 70D nylon keeps each size lean: 29g at 3L, scaling to 96g at 30L, so you can run several sacks in one pack or duffel without noticing them on the scale. Three distinct colors let you assign a color to a category (clothing, electronics, food) and pull the right sack without unpacking everything else.

A Closure That Holds Under Real Use

The tear-proof drawcord throat uses two hypalon pull-tabs and a Capture Cord Lock that cinches and stays cinched. Hypalon is a synthetic rubber that resists abrasion and UV degradation, so the tabs don't crack or fray after a season of hard use. Reinforced stitching on every stress point and overlocked fabric edges back up the closure, giving the sack structural integrity even when packed tight and shoved into a corner of a bag.

Water Resistant, Not Waterproof

The 70D nylon body carries a 2,000mm hydrostatic head rating on the fabric itself, and the non-PFAS DWR finish sheds incidental moisture. The white PU inner coating also helps repel moisture that does get in. That said, the Lightweight Stuff Sack has no taped seams and no roll-top closure, so it is water resistant rather than waterproof. Gear that must stay completely dry in sustained rain or submersion requires a taped dry bag instead. For clothing, sleeping bag liners, tent bodies, and other gear where splash resistance is enough, this sack handles the job at a fraction of the weight and bulk of a full dry bag.

Common Questions

Is the Lightweight Stuff Sack waterproof?

The Sea to Summit Lightweight Stuff Sack is water resistant, not waterproof. The 70D nylon body fabric carries a 2,000mm hydrostatic head rating and a non-PFAS DWR outer finish that sheds light moisture, but the sack has no taped seams and no roll-top closure. Gear that must stay completely dry in heavy rain or submersion should go in a taped dry bag.

Is this stuff sack suitable for storing a tent?

Yes. The Sea to Summit Lightweight Stuff Sack's durable 70D nylon construction handles tent storage well. The larger sizes (20L and 30L) are practical for tent bodies and rainflies, while smaller sizes suit tent stakes, guylines, and footprints. The drawcord closure cinches down on irregular shapes without difficulty.

What does bluesign APPROVED mean for this sack?

The bluesign APPROVED designation means the 70D recycled nylon fabric used in the Lightweight Stuff Sack was produced under standards that address resource efficiency and restricted substance use in textile manufacturing. The fabric is also RCS-certified recycled content and finished with a non-PFAS DWR rather than a PFAS-based water-repellent treatment.

How do the sizes compare, and which should I choose?

The Sea to Summit Lightweight Stuff Sack comes in 3L, 5L, 8L, 13L, 20L, and 30L. The 3L and 5L work for small accessories, cables, and first-aid items. The 8L and 13L suit a mid-layer or a set of camp clothes. The 20L fits a sleeping bag liner or a full clothing kit, and the 30L handles bulkier items like a tent body or a puffy jacket.

Are all colors available in every size?

Not all colors are offered in every size of the Sea to Summit Lightweight Stuff Sack. Spicy Orange is available in 3L, 5L, 8L, and 20L but not in 13L or 30L. Surf the Web is available in 5L, 8L, 13L, 20L, and 30L but not in 3L. Burnt Olive is available across all six sizes.
