In relation to harvesting clothes, there are five pieces to the set, namely.
-Gloves
-Boots
-Helmet
-Shirt
-Pants

All harvesting clothes are crafted, but I may be wrong. Speaking on crafted clothes,

Pristine clothes are different from A,B,C grades in that pristine contain a bonus to harvesting skill whereas lower grade clothes contain only the min unit per node hit.

When rare mats are used, they give another line called avg unit per node hit.

Each clothe piece takes one raw material unit to craft.

Each of the below recipes have the various specialisations, example, you can use the same recipe to make silkbloom harvester pants or silkbloom skinners pants, with the following exception - all helms dont have specialisations, and lower gloves do not have specialisations either.

In relation to crafted clothes, revolving around general harvesting skill required to wear,

x means no value obtained for this yet, need very high crafter to pls provide info for the x’s.
Also I think Pristine Ratty Leather Harvester Gloves has a bug, it doesnt give any bonus to harvesting skill, while all the rest do. Pls fix.

Special thanks to Pogar- Tharridon server for the majority of the information you see here.
