Product Details

Eliminate the Where is it? moments.

14g DCF stuff sack. 8.5L capacity. The rectangular base allows it to stand upright inside your pack, and the wide opening lets you see everything at a glance the moment you open it.

Typical cylindrical stuff sacks collapse inside your pack, causing the contents to sink. You want to organize your tent camping clothes, cooking gear, and rainwear into categories, but they all end up mixed together, which can be a minor stress. The Stand on was created to reduce that searching time.

Why do UDG stuff sacks stand on their own?

Under Dog Gear products are finished using bonding and crimping. Instead of sewing with thread, a special double-sided tape is sandwiched between the fabric layers and bonded with heat and pressure. This seam-free construction prevents water and odors from leaking, fully utilizing the airtightness of DCF (Dyneema Composite Fabric).
To create a self-standing stuff sack, the bottom needs to be precisely formed at right angles. While it's difficult to achieve precise corners with a sewing machine, bonding allows us to create this part by joining the fabric layers on a flat surface. The decision to eliminate seams has resulted in the added functionality of not falling over when placed down.

Assign a home for each subset.

The M size (8.5L) is ideal for medium-capacity items that you want to assign a specific home to, such as a full set of clothes for tent camping, cooking gear + tableware, or rainwear + insulation. If you decide, This M is for tableware, that M is for rainwear, the packing order and the order of retrieval at your destination will always be the same.
When there's reproducibility, packing before departure transforms from a task into a confirmation. It becomes harder to forget things, and once you find the first item, you know the next one will be easy to find – providing a sense of security.

For those who want something more compact, there's the S size (4L, 9g). We also offer a Food Bag (10L, 31g) specifically designed for food management.
