Alta Adventure PB30 Bag-In-Bag

The Alta Adventure PB backpacks includes the full size bag-in-bag (BIB) as standard, but some photographers have multiple kits, and rather than reconfigure the dividers for every trip you can buy an extra Alta Adventure BIB bag-in-bag. This then allows you to simply swap the bag-in-bag, leaving the kit you're not using safely stored at home. 

The Alta Adventure PB30 BIB is designed to fit the Alta Adventure PB30L models, but can also be used in the Alta Adventure PB40L models and Alta Adventure PB50L models to free up some extra space, but may not fit as comfortably.

This removable 14 litre bag-in-bag is designed for your camera kit (or other kit) with internal dimensions of 28 x 13-14 x 35.5cm.  This allows you to fit a full frame or APSC style camera with a 70-200mm f2.8 with an additional 3-4 lenses and additional accessories, though mix will clearly vary based on size of lenses.

Full access to your camera kit is through the rear of your bag, but you can also get quick side access to your camera, or set up the BIB for top access. 

The bag can be fully zipped up when stored at home to keep out the dust, so is great for storing your kit securely when not needed.

Specification:

The Alta Adventure Series:

Alta Adventure BIB are the removable inner bag-in-bags that are designed to fit the Alta Adventure PB models, with a choice of four sizes. This allows you to set up each bag for different kits and, rather than reorganising your bag every time, simply slot in the kit of your choice, leaving the other kit safely stored away at home.

Additional Products within the Alta Adventure Series include:

• Alta Adventure PB are backpacks that are designed to be the most capable choice for landscape and wildlife photographers needing to cover long and difficult trails, with the potential to camp out to catch that early sunrise or elusive creature.
• Alta Adventure LB are backpacks that are designed to be able to cover similar trails with a more traditional camera compartment setup that reduces weight. These models prioritise the day trip and camera kit over the ability to camp. 
• Alta Adventure W are comfortable waist packs with a removable waist belt and shoulder strap that allows them to be converted to a shoulder bag. They can also be attached to the front of any Alta Adventure PB backpack or any Alta Adventure LB backpack for extra storage on the go, with the freedom to explore at your destination.
• Alta Adventure BIB are the removable inner bag-in-bags that are designed to fit the Alta Adventure PB models, with a choice of four sizes. This allows you to set up each bag for different kits and, rather than reorganising your bag every time, simply slot in the kit of your choice, leaving the other kit safely stored away at home.
• Clipfast Straps are adjustable webbing straps with Clipfast attachment clips that allow you to attach larger items like tents and sleeping mats to the exterior of the backpack.  The backpack comes with a pair of straps, but if you want to carry additional kit then additional straps will be needed.

In Summary:

Whether it's to fit your Alta Adventure PB Backpack or be used to store your kit safely at home or in a different bag, the Alta Adventure BIB bag-in-bags are a lightweight and handy solution.
