UL Round Sack Custom's Commitment

🚩Customize your rounds

Customize the round size in 0.5cm increments to fit your gear.

Due to its characteristics, Dyneema® gradually wrinkles and changes the shape of the fibers as it is used, causing it to shrink.

If you pull it lightly, it will recover slightly, but please take this shrinkage into consideration in order to use it for a long time. We recommend a round size with a diameter that is 3cm larger than the largest diameter of your cooker, as this makes it easier to put in and take out.

If the cooker has a handle or something similar, take its size into consideration and leave some space to make it easier to take in and out.

🚩Customizable height

Customize the height to fit your gear in 0.5cm increments up to 50cm.

For example, you can customize the height to suit the items you want to put in, such as frying pans, cookware, clothes, sleeping bags, and tents.

Guide to determine height

We recommend rounding up the decimal point to the nearest whole number.
*For 0.8oz Dyneema®️ Composite Fabric, the fabric is thin and therefore flexible, so please add 0.5cm to the height calculated below.

🚩Minimized stitching and bonded construction to prevent contents from getting wet

The fabric is basically bonded together without being sewn, so there are no perforations where the bottom and sides of the fabric are joined, making it difficult for water to penetrate.

Additionally, the new UL Round Sack features double the width of the side and bottom bonding for added strength.

The bonding is less likely to come off than with the previous UL Round Sack, even when filled with items that tend to expand, such as down or a change of clothes.

*However, it depends on the amount you add, so be careful not to add too much.

Only the top handle and stopper are attached by machine.
Please note that this product is not completely waterproof.

🚩The rounded cylindrical base makes it easy to store

The rounded cylindrical bottom makes it easy to fit various types of cookware, including tall and flat cookware . Of course, you can also put things other than cookware in it.

*Please be careful not to stuff too much inside as this may cause the bonding to come off.

*If you don't pack too much inside, there will be less dead space in your backpack.

🚩Can be opened and closed with one action

The top can be opened or closed with a single action.

To open it, just pull the handle and parts, and to close it, just squeeze the parts.

This is actually very convenient, stress-free, and comfortable! It minimizes the hassle of opening and closing the door, and you can open and close it quickly.

🚩Ultra-lightweight, water-resistant Dyneema® composite fabric

This is the thinnest of YAMATOMO.FUN's UL Round Sacks and is designed with UL in mind, but as a stuff sack for use in mountain climbing, hiking, camping, etc., I think this thinness is about as thin as it can be when considering durability.

It can be used as a stuff sack to hold a cooker, down jacket, change of clothes, small items, etc.

DCF comes in a variety of thicknesses, and thinner thicknesses are lighter but less durable. Even water-resistant and durable DCF can develop holes, thin, or tear if rubbed against a hard object in the same spot for a long period of time.

Furthermore, due to its characteristics, Dyneema® gradually wrinkles over time and the shape of the fibers changes, causing it to shrink.

The shrinkage will recover slightly if you pull it gently, but if you plan to use it for a long time, we recommend choosing a larger size, taking shrinkage into consideration.

*Please note that wrinkles may occur due to the characteristics of the fabric during the manufacturing process.
