SoPack-4. Updated not only design but also dough also updated! !


A nylon fabric was selected with a 3-layer structure with a high density (no glossy mat thread). The fabric has a water repellent effect and is excellent in moisture permeability. I wrote in the previous blog, but it is comfortable to keep in the bag by making it easy for moisture permeability. If the package is sealed with a fully waterproof specification, the luggage is steamed, so it is easy to handle such a waterproof specification, except that it is used in full-fledged mountain climbing, etc.


A high density woven fabric is firmly water repellent. As a result, you can protect the backpack and the pitch pattern with an umbrella on a sudden rain or heavy rain day. Matt nylon is a urban impression from smooth and smooth image and an urban impression.
