Backpacking adventures give you many options to explore and people have different reasons or ways of travelling. I have been trekking in Central Asia, on adventure travel to Antarctica, on camping tours to the national parks of Africa, on wildlife observation in Alaska, on birding tours to Australia, South East Asia and Latin America and to many other once in a life time travel destinations.
As far as big backpacks go, I think North-face and Katmandu have some really good ones. Certainly a great choice for those after not just a budget case but the best backpack for air travel. While there travel accessories online australia might be some gray-area on the size of this bag and how many times I'll actually have to pay to check it, the Tortuga Outbreaker is still without a doubt one of the best backpacks on the market.

If you're not sure yet how to consolidate your stuff into a single travel bag, check out my columns on why you should pack light and five things you can leave at home More than any other travel advice, packing light is by far the most transformative.
One of the most important considerations when looking for this sort of backpack is how protected your devices will be inside it. This includes making sure the material is sturdy and water resistant so that all electronic devices are sheltered from the elements.

For the last two and a half years, I've been travelling around the world with my Osprey Farpoint 40 , and I love it. While it's not technically a female specific backpack, it comes in two different sizes, so getting a good fit should be possible for most girls.
The Osprey Farpoint 70 and Fairview 70 are just slightly larger versions of their 55 counterparts—anything we've said about the Farpoint 55 and the Fairview 55 also applies to them—and they would work well for those who want to go with the Osprey but need more room in the main pack.

Based on my experience and research, we decided that a travel backpack is something that can hold between 50 liters and 65 liters, with an integral, removable daypack; that has an internal frame with a hip belt; and that has some sort of cover to contain the straps, for easier storage on planes and trains.
Travelpack type rucksacks come with a daypack zipped onto it. This is a fantastic idea by manufacturers who realised that the average gap year traveller needs not only something to put their entire luggage in but also a smaller bag to carry around during the day.
As the best looking bag we tested, Osprey's big traveller's rucksack is also the most environmentally friendly, made entirely from durable, recycled fabrics - even the detachable raincover is recycled - with classy metal buckles and clips throughout.

The suspension system on this Kelty travel backpack is ridged, and light, and the straps and back panel are padded and meshed for cooling. Another great thing to look for is a pocket that stores away the backpack straps for transport, so your pack doesn't accidentally break a buckle as it spins around the luggage conveyor belt at the airport.
The best travel carry on bag for you is not necessarily the perfect carry on bag for me, so you must take the time to consider what it is you need out of your backpack. Overall, the Osprey 30 is a sturdy, versatile and comfortable pack with a durable material that resists wear and tear, from the jungle to the streets.
