## Our thoughts

The Stratos is one of Osprey's more adventurous models. A little larger than the Farpoint or Porter, you may find these bags too big for European or Asian airlines.

You'd have to check this bag in most circumstances, but maybe the extra space will be worth it. If you are genuinely backpacking around and trying to minimize the amount of laundry you'll have to do then this is the bag for you.

Osprey makes great bags so you can't go wrong with this one.

## Our verdict

### Reasons to buy

-   Osprey is one of the best bag makers in the industry.
-   Plenty of space for long, 10+ day trips.
-   Offers great ventilation for your back when in use.
-   Quality materials are used in creating this bag.

### Things to consider

-   The sleeping bag compartment is quite small.
-   Could use some side zippered pockets for your small things.

## What reviewers said

-   The Stratos 50 is Everything you need for multi-day hikes.
