The Java Sock - Made with recycled coffee grounds

Made with recycled coffee grounds

From cup to cloth

Spent coffee grounds are mixed and melted with recycled plastic bottles, then extruded into the fibers that create our Java Hiking Socks. The process requires minimal resources and utilizes sustainable technologies such as solar power, gray water recycling, and more.

made from recycled coffee grounds

We’ve transformed your morning cup and kept the life cycle of coffee going strong! By utilizing discarded materials like coffee grounds and plastic bottles, we’re keeping our waste streams small and making our impact big.

Neutralizes Odors

Coffee is a naturally odor-absorbing material and by weaving the grounds into the fibers, odors are trapped as you sweat.

Dries Ultra-Fast

The material is constructed with microscopic pores which increase its surface area, so moisture is spread throughout the material and the drying process is accelerated.

Eco-Minded Goods

snug and comfy

Maybe more of a 4.5 stars. Fits well and it's a nice feel. It doesn't fall down - very snug. Maybe on the verge of too snug? Will see how they hold up over time - but happy to have them in the sock rotation!

Great socks

Very comfortable good fitting socks. Will be buying more.

Nice socks !

The socks are soft and warm I like the idea the the bottom of the socks is thicker. Just wish they had better colors and basic colors like plain black.

Excellent! Even for small feet

Love ‘em. I have small feet, so “one size fits all” socks don’t really serve me well. These are excellent and fit well. Love the cute mountain design and eco-mindedness. Would recommend 👍🏼

You can never have to many great socks

These socks are amazing. They do exactly what the description says and look great. I like the natural earth tone the color is and the top of the sock does not feel constricting on my calf but doesn’t slide down either. Probably will purchase in all colors!
