The bag is really good, it’s done with very nice and pleasant materials. It’s good for cold or wet weather, it protects the instrument as good as hard cases can. The inside is done with very pleasant material so it doesn’t harm the instrument’s varnish.
The only minus is the weight, it’s quite heavy. The bow box is very protective, but it puts additional weight on your back. I used for couple of weeks every day and by the time I could feel the weight more and more with a bit discomfort.
The bag is really good for international travel, but it’s not as lightweight to carry every day as student or orchestra musician. Of course the weight is subjective thing, for some cellists it can be ok, for some others opposite.
And the wheels are super good, the handles are very good, the accessory pockets are also very good.
