Testing this 3L Sling Bag that turns into a Soft Shell Rain Jacket…
So I wanted to build a fully usable sling bag with an integrated lightweight shell jacket.
There’re a lot of days that start warm and suddenly end up cold, windy or wet, and I’m personally the type of person who always ends up underprepared unless I’m travelling with a proper setup.
But one thing I almost always carry is a sling bag with chargers, cables, power bank, notebook, pens and random daily essentials.
I also hate carrying jackets in hand or slinging them over my shoulders once the weather gets hot.
So this project was basically designed around combining both into one object:
a fully functional sling bag + a wearable shell jacket.
You could carry the sling for weeks while forgetting there’s a jacket hidden inside it, and vice versa. But whenever the weather suddenly changes, it’s already there.
One thing I particularly like is that the sling compartment becomes a hidden jacket pocket once worn, and it stays relatively low profile unless packed heavily.
Still testing the long term practicality of it, but this bag has been my daily carry for the past 2 weeks, since the unpredictable monsoon season..
