Windermere Sling Bag

All posts may contain affiliate links.


This sling bag is the ideal cross between a backpack and crossbody bag. This mid-sized bag is comfortable to wear and not difficult to sew.


I love a great backpack but they can be awkward. What was needed to fill the gap and still work to carry hards-free was a sling – somewhere halfway between a crossbody bag and a backpack. It is secure, accessible and easy to carry. It has to have lots of pockets too to carry your essentials but it mustn’t be too big. Or too small. Quite a big ask but I think that we have achieved it!

The Windermere features a lapped front zipper pocket and inside a zipper box pocket and two lined slip pockets. It has a sturdy strap and is comfortable enough to carry all day.
