Upgrade kits can be used on clothing to add stats to them; clothing has different slot orientation among each item. You can salvage average+ quality kits for Tools tools and Precious ore precious ore.

You cannot equip multiples of an upgrade kit with the same effect on the same clothing item, however you can spread them across different items. When you have the same update kit on multiple clothing the effect is cumulative for passive effects, and will have multiple chances of firing (even at the same time) for chance based ones.
