CARE GUIDE

Wash freely.

To make it last, turn it inside out and put it in a wash bag before washing.
Use neutral detergent. If odor bothers you, add about a teaspoon of oxygen bleach (such as OxiClean) — it sanitizes and reduces smell.

It's fine to put it in the dryer.

To make it last longer, dry it in the shade.

Please hand wash in lukewarm water. Use a small amount of mild detergent, gently press and wash, rinse thoroughly, and then let it air dry in the sun.

Store fully dry. Long-term storage inside a stuff sack accelerates material degradation. Mold is hard to remove, so always hang loose and open when storing for long periods.

Please wash it as soon as possible after use. Washing it in a laundry net will make it easier to find.

Sweat and sebum remaining inside can cause deterioration.

After shaping it, dry it in a well-ventilated place away from direct sunlight.

Using a dryer can cause shrinkage, which can impair the fit, but even if they shrink in the dryer, they will return to their original size once you wear them.

Be careful not to insert toes into the wrong opening.
Wearing them inverted can cause tearing or blisters.

Please allow them to dry completely before storing. The lifespan of socks is approximately 100-150km with hard use on trails, and about 6-12 months with everyday use. It's time to replace them when the fabric at the heel or toe starts to thin. You can extend their lifespan by rotating between 2-3 pairs.

It can be washed with water. Please rinse it gently with lukewarm water. Dirt and sand that have gotten inside can be removed by rinsing it with water and shaking it. Avoid cleaning with strong solvents or alcohol, as this may damage the resin.

Please make sure to drain all the water. If water freezes while the container is still full, it may cause damage.

The GLOW (luminescent) model absorbs light and glows in the dark. The luminescence lasts almost indefinitely, but regular exposure to light will maximize its brightness.
Leaving it on a car's dashboard or in direct sunlight for extended periods can cause deformation and deterioration.

As this is a safety device, please check for cracks or damage before use. Minor cracks caused by impact may result in changes in sound quality. If the sound when you play it is different from before, we recommend replacing it with a new one.

After each use, wash thoroughly with food-grade mild detergent and a sponge. Remove and wash the gasket. Leaving food residue in the product can cause spoilage and mold, so rinse it immediately after use, even on the trail.

It is also dishwasher safe.

After washing, remove the lid and gasket and allow it to dry completely. Sealing it while water droplets remain can cause mold and unpleasant odors. It is best to let it air dry upside down.
You can use a dishwasher, but please avoid using the high-temperature drying mode that exceeds 90 degrees Celsius.

Please store the product with the lid slightly ajar or removed. Long-term storage in a sealed container can cause moisture to build up inside. Replace the gasket when it hardens or cracks. Replacement gaskets can be purchased from our online store.

Small holes and tears can be temporarily repaired with repair patches. Apply tape to the back and then place a patch with rounded corners on the front to prevent it from peeling off. For major damage or structural breakage, please use our repair service .

If you find any loose threads, it's important to repair them as soon as possible. Use a sewing needle and thread to backstitch along the original seam. You can easily do this by hand even without a sewing machine.

The belt portion may be difficult to sew by hand.
For major damage, please use our repair service.

Buckle damage and cord wear can be replaced with parts of the same specifications. Please check the buckle size (tape width) and purchase a similar type at an outdoor shop, or contact us for support and repair.

The ultralight culture began with "making it yourself." In the 1990s, Ray Jardine, dissatisfied with ready-made gear, began sewing his own, which is the origin of MYOG (Make Your Own Gear). It doesn't have to be perfect. Making your own gear with your own hands—that process itself is the essence of MYOG.

MIYAGEN's MYOG kit is a pouch-making kit that can be made with just a sewing machine and thread. Because it reuses leftover fabric scraps from product manufacturing, no two kits are exactly alike. The 16-page instruction manual includes everything you need for your first MYOG project, from basic material knowledge and pattern explanations to customization tips.

For caring for your DIY gear, please follow the care instructions for the materials you used. For the fabric included in the kit, refer to the care instructions in the GEAR & PACKS section above. If you're concerned about frayed seams, be sure to check the SELF REPAIR section as well. Because you made it yourself, you know how to repair it. That's the strength of MYOG (Make Your Own Gear).

The appeal of MYOG isn't just about creating something from scratch. Modifying existing gear to suit your own style—known as "MOD"—is also a crucial aspect of ultralight culture. Removing unnecessary parts to reduce weight, adding pockets, changing strap placement—optimizing what doesn't suit your hiking style with your own hands—that's the fun of MOD.

Understanding the properties of the materials before starting will make a difference in the final result. Checking the care methods for each material in each section of this page will help you make informed decisions when making modifications.
