* Main Compartment:
This is used to carry the majority of equipment and is loaded from the top and is partially closed by a drawcord, with the lid providing a weatherproof seal. Many of these rucksack are extendible (i.e. the lid can be raised and the snow lock used for storage of extra gear) which can be useful for transporting extra equipment to a fixed campsite, or to the foot of a climbing route.

* Base Compartment:
Accessed by a zipped entry, it may have compression straps to hold soft items such as sleeping bags securely. The “shelf” dividing the main and base compartments can often be removed by means of a zip of drawcord to give the option of one large compartment.

* Loading Straps:
Compression/Accessory straps are those which run around the sides of a rucksack and are used to compress it so that the weight is held close to your back when the sack is partially full. They also allow additional side pockets to be fitted to give extra space, or they can be used for attaching excess gear (sleeping bag mats, skis, tent poles, fishing rod, snow shovel etc.)
Closure/ Profile Straps run vertically around the sack. At their top end they are used to hold the lid closed, but at the base there may be extra buckles which can be used to reduce the width of the base of the sack.

* Pockets:
The lid pocket is useful for carrying items which are most frequently needed when on the move, as the zip entry is usually behind the neck where it can just be reached. Care is needed, however, to ensure that small items do not fall out of the pocket when it is opened. If travelling with a companion it may be better to use the side pockets, as your companion will be able to reach into these without you needing to take off the rucksack. They can also be used for fuel bottles and things which may contaminate other gear.

* Accessory Patches:
Used to strap larger items to the outside of the pack (Such as tent poles etc)

* Lid:
Usually elasticized around the edges for a more weatherproof seal and held closed by snap fit buckles on the profile straps. On most sacks the lid is stitched down on the side next to the wearer’s back, but on others it is held by straps all round. This enables the lid to be raised on extendible sack, and sometimes totally removed to form a separate day sack.

* Ice Axe Loops:
Used to carry ice tools. Some are adjustable for different lengths of shaft,If carrying modern modular Ice tools, many of which have bulky head designs, check that the lower loops is large enough to accommodate them, or preferably adjustable.

* Crampon Patches:
Double thickness material with loops for fastening crampons to the outside of the sack. They can be used as extra accessory patches when not carrying crampons.
