Pack yaks are level 114 combat Summoning familiars with the second largest inventory capacity among all the Beasts of Burden (behind pack mammoths). They have the capability of holding up to 30 items for a player, whose value can be no more than 15,000,000 coins each (90,000,000 coins in total). Pack yaks also have a special move called Winter Storage, which allows for instant banking, making it a popular familiar to take to most areas. Similar to the unicorn stallion and bunyip, a pack yak will fight only when attacked.
The pack yak can be communicated with if the player is wearing a pack yak mask.

A pack yak pouch is made by using a Summoning pouch on a Summoning obelisk with 211 spirit shards, a crimson charm and a yak-hide in the inventory, and 96 Summoning. Making the pouch earns 422.4 experience points. Using the pouch to summon a pack yak gains 4.8 experience points, and costs 100 Summoning points. Each pouch summons a pack yak which stays alive for 58 minutes before needing to be re-summoned.

Winter Storage is the special move for the pack yak, which when used on an item in the player's inventory, instantly banks it without the need for visiting a bank in person. This allows players to remotely bank items while remaining in a certain area for extended periods of time. When using the scroll on noted items only one item will be banked per scroll. The special move is also used while player killing because the special move can bank the gear of the player, thus not risking the items should they die. As of June 13 2016 update Winter Storage scrolls banking ability can no longer be used above level 30 Wilderness.
As the familiar lasts for 58 minutes, summoning the pack yak with a full special moves bar provides 1800 special move points over the course of its lifespan, allowing you to potentially use the Winter storage scroll 150 times. In cases where one will acquire more than 150 drops within that one hour, alternative methods such as Magic notepaper may be necessary for banking in addition to the Pack yak.
Casting the spell Make Leather and crafting dragonhide bodies will allow the yak's inventory to hold 90 dragonhides' worth of dragonhide bodies, and so players wishing to train at Green or blue dragons may wish to use this method to bank all of the dragon bones and dragonhides that the dragons will drop. To maximise efficiency, players should use Winter storage to bank the bones immediately, cast Make Leather 3 times when 15 dragonhides are acquired, craft 5 dragonhide bodies and store them in the yak, then repeat the process.
In the Wilderness, Winter Storage only works up to level 30 Wilderness. Players should be aware of this if they need to bank items and are deeper inside.
Winter Storage cannot be used to bank winter storage scrolls.
- In the original update, pack yaks could only hold 10 items, however the items would stack.
- An update to the Crucible prior to its removal from the game prevented players from using winter storage scrolls to bank items in the minigame, producing the error message "You cannot use that spell whilst in the Crucible."
- Prior to the patch notes of 13 June 2016, Winter Storage could be used at any level of the Wilderness.
- The pack yak was given dialogue when it was released in 2008, but the dialogue was inaccessible until the release of the pack yak mask in 2018.. This also makes the pack yak understandable without having 10 Summoning levels above it, much like the iron and steel titans.
