We use 4 climates:

Materials

According to the internet, these are the main pros and cons:

Material Pros Cons Climate
Polyester (P) Lightweight, quick-drying, moisture-wicking Can retain odors, not as breathable as other materials W, M, C
Nylon (N) Durable, abrasion-resistant, quick-drying Not as breathable as other materials, may retain odors W, M, C
Spandex (S) Stretchy, allows for freedom of movement Not moisture-wicking, may retain odors W, M, C
Hemp (H) Sustainable, naturally antimicrobial Can be heavy, may not be as durable as synthetic materials M, C
Bamboo (B) Sustainable, moisture-wicking, naturally antimicrobial Can be heavy, may not be as durable as synthetic materials W, M, C
Cotton (C) Comfortable, breathable Absorbs moisture and dries slowly, not suitable for wet weather W, M, C
Merino wool (M) Naturally antimicrobial, moisture-wicking, warm even when wet Can be expensive, may be fragile and prone to pilling W, M, C, S

"Synthetic" fibres (SF) refers to polyester, nylon and spandex (among others not mentioned)

Personal experience:

Material Clothing item Findings (focussed on usage, not production)
Polyester Shirt It's good. Like, really good. The only downside: it has a plastic feel to it which gives a colder perception.
Hemp Shirt Hemp/cotton blend.
Overall really good, lightweight, very breathable and durable. Although the white isn't as white as it could be, but that's probably due to lack of paint used in production.
However it's slightly itchy even when mixed with cotton.
Cotton Shirt Baseline to compare everything else to.
Merino Shirt, underpants, leggings <3
