I made a beer sacoche using Tyvek from DuPont. This "Nonbe-san mk5" was made so you can wander around at campsites, festivals, and tent sites with your favorite beer. ※Even if it's "5 seconds before you spill it," this will prevent spills! I'm a clumsy person, to be honest. I knock over my beer within 5 seconds of setting it down. The opening gets gritty. For a broke hiker, a mess at the campsite is a life-or-death situation (crying). So, I thought, "If I hang it from my neck, I won't knock it over!?" and made it with that simple idea. It's also useful when you take your beer from the tent site to watch the alpine glow. If I put it down, I'll knock it over again while taking pictures (lol). Anyway, beer drunk outdoors is the best, right! The size is perfect for a 350ml can. The weight is 13g-14g (there may be slight individual differences). The special feature is that the neck strap length can be adjusted from 42cm to 22cm when worn around the neck. You can also remove the neck strap and attach it to a backpack or sacoche to use as a snack pouch. The usage is up to you! ※Wrinkles will occur due to the nature of the material (Tyvek sheet). ※Please understand that it will be folded small for shipping. ※Please note that only the bag is included; other items are not. ※Each item is made with care, but there may be slight individual differences. If you are looking for perfection like a mass-produced product, please refrain from purchasing.
