Inside, Thule has equipped with precut foam rot (type pool board) which gives the whole a positive buoyancy and helps flush equipment without fear. The top of the case is equipped with dual pocket, perforated and the other completely closed (small items such as SD cards' will be well protected).
A GoPro or SJ4000 with their accessories find their place and will be well protected, but I think this case and really great, it is ill-suited to aviation or space is limited, but the finish is really far above the competition .
To: quality, functionality, guaranteed for 25 years.
Cons: price, its large size.
Conclusion: Thule offers here a high-end product of high quality, well researched and remarkable finish, guaranteed for 25 years. Its price is quite high (compared to the competition), its imposing size does not allow it to be forgotten when the time comes (whether in a suitcase or hanging from a hook), and it ''s too bad.
There are similar products cheaper, more compact and interesting as the "Small IPOW" I suggest you not to overlook if your budget is tight.
