Carefully crafted design and functionality
The base doubles
This design allows the bottom area to double when the zipper is fully opened, allowing it to expand and become like a bathtub.
This base doubles, so

The contents are easy to see, allowing you to quickly find what you are looking for, and since it can be unfolded while still in UL FAK Packing, small items do not get scattered or lost, and it is hygienic as it does not need to be placed directly on the ground.

Daisy Chain
A daisy chain is attached to the top with grosgrain ribbon, making it easy to take out of the backpack and can also be attached to the outside of the backpack.
You can also hang it on something.
The back of the daisy chain attachment point is reinforced and sealed with Dyneema® tape.

The design and shape of the lid, which opens wide and doubles the floor area when fully opened, is actually a shape that has long been common in small storage devices.
However, there was nothing suitable for mountain climbing, hiking, camping, etc.
That's why we created UL FUN Packing for mountain climbing and hiking.
[UL FUN Packing] is available in four sizes: L, M, S, and Slim.



Carefully selected ingredients
Dyneema® composite fabric
The fabric of the main body is made by Ambient Protective Materials (formerly DSM), a company that is known for its commitment to quality. It uses an ultra-high molecular weight polyethylene (UHMWPE) composite fabric, Dyneema® Composite Fabric (hereinafter referred to as DCF).
DCF is a water-resistant, extremely strong material, yet extremely lightweight.
The stitching is carefully sealed with the same DCF tape, which takes time and effort, so the contents will not get wet even if the bag is splashed with water or in light rain.
On the other hand, it is okay to put wet items inside.
*Not completely waterproof.
* As DCF is used, it will gradually wrinkle and shrink due to changes in the shape of the fibers. Pulling it gently will restore some of the shrinkage.
"Dyneema® composite fabrics break new ground in strength and durability. Compared to 500D nylon, Dyneema® composites offer dramatically improved tear, puncture and abrasion resistance, despite their reduced weight and bulk. They can also be customized to optimize strength, elongation, weight and overall thickness, specific thickness or thickness along predetermined load paths. The ability to customize flexible composite fabrics allows for use in a myriad of applications and industries, from outdoor sports equipment to emergency medical products."

Fabric thickness
DCF has a variety of fabric thicknesses, from ultra-thin to thick. The one I used this time was 1.43 oz/yd2.
1.43oz/yd2 means that one square yard of fabric weighs 1.43 ounces, making it the thickest single-layer fabric from DCF. It is a slightly stiff fabric.
A stuff sack, which is used to store and organize various items, needs to be lightweight, water-resistant to some extent, and durable enough against external influences. We chose this thickness of 1.43 oz/yd², which strikes the perfect balance between strength and lightness.
Waterproof zipper
The UL FAK Packing lid uses a YKK waterproof zipper.
Note: Not completely waterproof.
