What brand of camera bag is good?

That depends on what equipment you have.

Luxury brands in camera bags are: Buckingham, British handmade bags, which are expensive;

National geography, canvas design, big brand, but less protected;

The old brand KATA in the camera bag is of good quality and can be used for reference;

NAGA, a domestic boutique, is very good in materials and workmanship, and the price is kind. Suggestions.
