This guide is designed to assist you with crafting the necessary items you need for upgrading your equipment and carrying capabilities. As some skins are used in more than one crafted item, check to see which one is more important to you at the time before actually crafting. Make a copy of the list and mark them off as you go which will help you keep track of what you still need.
The are listed in order of importance and collection requirements. You can collect them out of order as well and they will be saved until they are ready for crafting. I suggest you craft as soon as you can to free up space in your Rucksack, important early in the game. I have added locations in brackets (...) that indicate where you can obtain the less obvious last items to be crafted as they are sometimes tricky to know where they are. It also helps with the order in which you can complete certain items to suit yourself and of course where you may be at the time. Also, if you do not wish to do that at the time and you have cleared the Outpost you can fast travel back to complete it later as required.
