How do the side pockets also serve as vents?

While reading the jacket's description, you might notice the mention that the side pockets serve a ventilation function in addition to holding belongings. You may wonder about the principle behind how simply opening the pocket zippers can cool the heat inside the garment.

hmmm editorial answer

This is because the large side pockets, made of net-like mesh, serve both the purpose of holding belongings and acting as vents that create a path for wind to cool the body when the zippers are opened.

What difference does the chest pocket packable design mentioned in the description make in actual use?

Packable clothing often comes with a separate storage pouch, which can be cumbersome to keep track of. One wonders how folding the garment into the chest pocket itself differs in terms of usability.

hmmm editorial answer

Because the storage pocket is integrated onto the exterior, you can easily fold and carry it without having to bring a separate pouch or worry about losing it.
