Polypropylene

Whether polypropylene is breathable and/or moisture wicking, seems to be up for debate, as well as dependent on how it is weaved, though most sources lean towards agreeing that it is mostly both.

Apparently, polypropylenes moisture wicking abilities come from it’s water resistant/repellent properties. As it is unable to absorb moisture, moisture passes completely through the fabric then quickly dries.

Its pros are that it’s lightweight, strong and durable, meaning it’s resistant to tears, abrasions and chemicals.

However, as it’s a synthetic material, it retains odours and can grow bacteria on it. This isn’t it’s only con, it’s also melts at what is referred to as a relatively low temperatures, and degrades if exposed to sunlight for too long.

Two things I couldn’t find out about polypropylene is if it protects you from UV rays (which due to it being UV degradable I would guess it doesn’t) and if it’s stretchy.

A could be pro or con, depending on where you live and the time of year it is, is that traps heat.

polypropylene can either be hand or machine washed, but only at cold to cool temperatures, and should be aired dried.

Don’t store in sunlight.
