If you are looking for a rucksack to take on a walk for more than one day, then I recommend a 65 litre rucksack. This size is actually pretty large, but it will be enough to hold all your spare clothes, food, camping equipment etc. and not be too heavy to carry.
When looking to buy a 65 litre rucksack, there are a number of key points to look out for. To illustrate these I'm going to use a North Face Rucksack, the Terra 65, as an example.
With a larger rucksack you are carrying more gear, so look for a rucksack that has a well-designed inner compartment that allows you to organise your gear and access your equipment quickly and easily.
In a 65 litre rucksack, you are carrying more weight, so look at how the rucksack is designed to help you carry that extra weight more comfortably. It must have a structure/skeleton that distributes the weight well. Also, can you adjust the straps etc. to fit your body shape?
As you are carrying the rucksack for more than one day, it must be comfortable. What features does the rucksack have that increase your comfort? A simple, lightly padded harness is sufficient for a day sack, but for larger, heavier loads, a more sophisticated back system is essential to provide a stable load distribution. For climbing and rough terrain you will want a pack that fits your back, but for days of trekking the priority may be a generously padded hip belt!
As you are carrying more weight, the rucksack must be robust and well made in order to cope with the extra load. Additionally, it must protect your gear from the elements.
Does the rucksack have any features to keep your back dry and comfortable?
Does it organise your gear and allow quick access?
The North Face Terra 65 rucksack has one large central compartment, which doesn't sound like a great way of making your gear accessible, but there is a clever trick: a side entrance. This additional entrance makes it easier to locate items buried deep in your bag. There is also a neat, segregated sleeping bag compartment that keeps your bag safely tucked away until it's needed. There are no side pockets, making this North Face rucksack relatively sleek, but it does have a spacious pocket on the fixed lid and a front pocket made from stretch material. The latter is a good place to store waterproofs or to pack thermal layers for quick access. There are trekking pole loops, compression straps, lash points and tool loops to allow you to secure extra equipment onto the outside of the pack.
How is the rucksack is designed to help you carry that extra weight more comfortably?
With these larger rucksacks, they are designed to carry heavier loads by spreading the majority of the weight to the stronger muscle groups around the pelvis. This reduces strain on the weaker back muscles and spine. The rucksack does this by having well-padded shoulder straps and a large hip-belt, which holds the weight around your waist. As it takes a lot of weight, it is important that the hip-belt is wide, well padded and easily adjustable. In the Terra 65, The shoulder suspension system is fitted with aluminium stays that effectively transfer the load from the pack to the waist to make the carrying very comfortable.
What features does the rucksack have that increase your comfort?
The Terra 65 has the Opti-Fit suspension system, which is adjustable, allowing it to be adjusted to fit your back perfectly. It also makes carrying the rucksack feel very comfortable. The shoulder harness and load-spreading hip belt are well-designed to fit well and carry the weight effectively. It also makes the rucksack very stable, with no leaning either to the back or side. However, the back system does add weight to the rucksack, so you have a choice: extra weight with extra comfort or a super-light rucksack that maybe isn't so comfortable.
Is it adjustable to my own body shape?
Pull the catch at the base of the back system, and you can slide the shoulder straps up and down to adjust to the back length. The hip-belt is adjustable at 3 points to help distribute the weight correctly.
Is it well made, in order to cope with the extra load?
The rucksack is made from ripstop polyester which is showerproof, resists tearing and is long-lasting. The load-spreading hip belt is lined with soft tricot to make it feel comfortable. The internal frame is made from Polyethylene and aluminium, making it both light and strong. The shoulder straps and hip belt are dual-density padded.
Does it protect your equipment from the elements?
A rain cover is included which doubles as a pack protector when travelling.
How does it keep your back dry and comfortable?
The rucksack includes a 'Verti-Cool' back panel - essentially a vertical, mesh channel on back panel that runs along your spine to keep you well-ventilated. The Terra 65 is made with air mesh fabric in high heat areas to improve ventilation.
In summary
The North Face Terra 65 rucksack light,http://www.cheapnorthfacejacketssale.co.uk/north-face-hoodie-womens-north-face-hoodie-c-8_10.html, easy to use, and has capacity for spending a number of nights in the hills where a certain amount of equipment is needed. It protects your gear, organises it and makes it easily accessible. Some people think it is a bit too heavy for a lightweight expedition of less than 3 days. It's not an ultralight rucksack; it is built to be comfy. The key feature of the North Face Terra 65 is that it is a great combination of comfort and capacity.
