This is a Polartec Power Grid fleece. The size is likely a men's L, but the fit isn't loose; it's more of an alpine fit. It's a JP 2XL in women's size. Thank you.

It uses Polartec® Power Grid fleece with a three-dimensional grid structure, providing moderate warmth while also offering high breathability, allowing for activity in low temperatures and keeping the inside of the garment comfortable and dry.
