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.

Awesome socks!

I work in a wet environment and these socks kept my feet nice and dry for eight plus hours. Great investment I will definitely get more!

Go to Hiking/biking socks

Worn them a few times downhill mountain biking. The best test so far was wearing them to summit 3 Fingered Jack 12mile round trip. 3 miles in there was nothing but snow had crampons my feet got a little wet from snow but socks dried out super fast. I have sensory issues when wearing certain socks never have any issues with these.

Security Blankets for my Feet

This socks are so comfy. At home after a long day and probably 5-10 miles of walking, it was so nice to put these on for the first time. It was almost a massaging feel when I put them on. I look forward to hiking soon, in the meantime, they are my evening security blankets for my feet. They are extra comfy and I like that they can be worn as knee-highs or a shorter sock.

Coalatree is my new go to product.

Get them

Another great product from Coalatree. I haven't taken them on a hike yet to fully test but I have worn then all weekend since they arrived. They're super comfortable and soft. My feet feel cool in my danner boots.
