Sea to Summit Ultra-Sil Shopping Bag

The Sea to Summit Ultra-Sil Shopping Bag is a 30-liter reusable carry bag made from 30D siliconized CORDURA nylon, the same fabric used in Sea to Summit's pack covers, compression sacks, and stuff sacks, and load-tested to support 130 kg (286 lb). It weighs 57g and packs to 4.8 x 4.8 x 17.5 cm, small enough to clip to a key ring with the attached carabiner. It is available in Spicy Orange and Blue Atoll.

Strength That Holds Up to Regular Use

The Ultra-Sil Shopping Bag is built from 30-denier siliconized high-tenacity CORDURA nylon, a fabric chosen for its exceptional strength-to-weight ratio. Bar-tacked, reinforced stitching at every key stress point means the bag handles repeated heavy loads without the seams or handles giving out. Under test conditions the bag has supported 130 kg, so a full grocery run or a loaded haul from a camp supply stop is well within its range. That kind of durability in a bag this light means it earns its place in a kit rather than getting left behind because it is too bulky to bother with.

Small Enough to Always Have On Hand

The Ultra-Sil Shopping Bag packs down to 4.8 x 4.8 x 17.5 cm and weighs 57g. The attached carabiner clips directly to a key ring, so the bag is available whenever a carry need comes up: at a trailhead gear shop, a farmers market, or a grocery run between camp days. It also fits in a jacket pocket or a purse. When a grocery spill happens, the bag is machine washable.

Specifications

Who This Is For and Isn't

The Ultra-Sil Shopping Bag suits anyone who wants a compact, durable reusable bag for grocery runs, camp resupply stops, or everyday carry, particularly those who need it to stow on a key ring or in a pocket so it is always available. Its 30L capacity and tested load strength handle a full grocery haul without concern.

The bag has no zip closure and no internal pocket; buyers who need to secure contents or organize small items inside the bag will find it does not meet that need. It is not designed as a primary travel daypack. For that use case, a structured daypack with closure and organization is more appropriate.

Common Questions

Is the Ultra-Sil Shopping Bag machine washable?

Yes, the Ultra-Sil Shopping Bag is machine washable. If a grocery spill or other mess gets inside, the bag can go straight into the washing machine without any special treatment required.

Does the bag have a zipper or an internal pocket?

No. The Ultra-Sil Shopping Bag is an open-top bag with no zip closure and no internal pocket. That design choice keeps the packed size as small as possible. Adding a zipper or pocket would increase the packed dimensions.

How does the Ultra-Sil Shopping Bag pack down, and how do you carry it when not in use?

The Ultra-Sil Shopping Bag packs to 4.8 x 4.8 x 17.5 cm and weighs 57g. An attached carabiner lets it clip directly to a key ring; it also fits in a jacket pocket or a purse so it is ready whenever a carry need comes up.
