If you ask me, part of the fun that comes with building a wardrobe of menswear essentials is stumbling across a piece that looks like it’s already a much-loved favorite, already a piece you’ve had for years on end. Take the Outerknown Sur Pocket Sweatshirt. It’s got plenty of the right style details going for it, starting with the garment-dyed finish for what the famed sustainable brand calls a “soft, lived-in feel.”

That alone makes it one of the best sweatshirts for men, especially in terms of laidback spring style, but as with all things Outerknown, there’s plenty more to love about this ultra-sustainable brand.

Hopefully, you’re at least a bit familiar with Outerknown, the brand founded in part by surfing legend Kelly Slater — and founded with a fierce mission to produce some of the best sustainable menswear on the market, no less. They’ve done that through using upcycled and recycled fabrics, plus eco-friendly materials, including hemp (which grows with far less water than other crops) and organic cotton (which cuts out harmful chemicals in the production process).

Both of them are front and center in the Outerknown Sur Pocket Sweatshirt, and you can also find a similarly sustainable approach when it comes to the famed Outerknown Blanket Shirt and one of the brand’s stylish polos, to name but two Outerknown must-haves.

The entire Outerknown Men’s Collection is focused on that sustainable approach, which just so happens to yield some seriously stylish results, for good measure. The Outerknown Sur Pocket Sweatshirt, available in five pleasingly faded colors for utterly classic warm-weather style, looks just like a classic sweatshirt you’d find tucked away in a lakehouse closet or at a vintage shop, with all the right details (including raglan sleeves and that useful chest pocket).

It’s made from a 55 percent hemp-45 percent organic cotton blend, with the kind of soft, easygoing feel that pairs up perfectly with everything from tailored joggers to chino shorts for a spring bonfire. It just doesn’t quite get better than the Outerknown Men’s Collection, this sweatshirt very much included, so upgrade your spring layering game in eco-conscious fashion right now.
