Not your regular t-shirt, the Snow Peak Polartec Power Dry T-Shirt is made from a really clever fabric called Polartec Power Dry. Not only is this stuff really lightweight, but that micro-grid pattern means it’s highly breathable too—making this a good option for running or fast-hiking. If you’re after a slice of technical performance, but don’t like the fitted, overly-slim shape you usually get with sportswear, then this is the perfect choice.
