Why do the side pockets on the Yarrow Hiking Pants have different opening and closing methods, using a zipper and snap buttons?
When looking at hiking pants, you come across a configuration with both a zippered pocket and a snap button pocket on the sides. With different opening and closing structures for the two pockets, one wonders how each is practically used during actual hikes.
It is a structure divided by storage method so that valuables easily dropped can be completely locked with a zipper, while frequently retrieved items can be taken out quickly using snap buttons.
One side closes with a zipper, and the other fastens with snap buttons. In addition to the basic front pockets, the Yarrow Hiking Pants from ostrya feature both a side zip-up pocket and a snap pocket on the sides[1]. As the opening and closing structures differ, their uses naturally divide as well.
It locks securely. Because the opening interlocks and closes, the pocket with the zipper poses less risk of contents falling out even when taking large strides uphill or bending over. It is suitable for storing belongings that must never be lost on the trail, such as car keys or cards.
On the other hand, the snap button pocket focuses on retrieval speed. Prying open the button with your fingertips opens it immediately, making it easy to handle the pocket even while wearing gloves. It is great for storing items that need frequent access, such as trail snacks consumed without stopping your stride or a handkerchief.

The internal lining material and specific storage capacity of each side pocket have not yet been confirmed in official materials.
