HEAD TO HEAD
Looking for a BACKPACKING RUCKSACK that will swallow all your gear with ease, while remaining comfortable over multiple miles? Here’s our pick of the best 50-litre plus packs around.
CAPACITY
For a big walk – anywhere from a few days to a few weeks in length – most backpackers will need a rucksack of 50-65 litres. Manufacturers calculate pack volume by filling a pack with 20mm plastic balls, which are then removed and placed into a volumetric cylinder. Most brands (but not all) include the pockets in this calculation, while others maximise volume by unrolling storm collars and roll-top closures. This explains why some packs of equal volume may not appear to be the same size.
MAIN COMPARTMENT ACCESS
Access is usually via a lid with a buckle closure, though minimalist packs might use a zippered or roll-top closure instead. Both have their pros and cons. The latter saves weight, but a lid usually offers more storage. If you prefer a lid, look for a floating lid, which is attached to the pack via adjustable webbing straps rather than being fixed. This allows you to ‘overstuff’ the top of the pack to carry extra supplies.
HYDRATION SLEEVE
Most modern packs are now ‘hydration compatible’, meaning they have an internal sleeve or hanging strap for a water reservoir, a port to feed the drinking hose through and often a hose clip on the shoulder or chest strap.
FRAME
The frame provides load-carrying rigidity and stability. Lightweight packs may have just one or two metal stays, a plastic framesheet or even be completely frameless, while more conventional packs have an internal perimeter frame.
EXTERNAL POCKETS
A front stretch pocket is useful for stowing extra layers. Side pockets are good for water bottles or flasks. Hipbelt pockets are handy for smaller items like snacks and tech devices, as is a lid or top pocket.
INTERNAL POCKETS
Internal pockets are great for stashing keys and valuables. Many packs have an inner security pocket with a key clip for this purpose.
COMPRESSION STRAPS
Most packs have compression straps or cords to cinch in the load for added stability. They can also be used to carry extra gear on the outside of the pack or underneath the lid.
SIZING
To ensure a good fit, many packs now come in different sizes (including women’s-specific versions). Others feature adjustable harnesses. To find your size, calculate your back length by measuring from your C7 vertebra (the bony bit at the back of your neck) to your iliac crest (the top of your hips).
BACK SYSTEM
A ventilated back panel maximises airflow. So
