Product Description

Hyke & Byke - Gear that Gives

"Our philosophy is to offer the best products at the best value for the best purposes." Daniel E., Founder 

ELIMINATING POVERTY THROUGH MICROLOANS
Hyke & Byke is a small but rapidly growing, independent outdoor gear company that was inspired and built by a group of entrepreneurial outdoors-men who wanted to use their passion for the outdoors to make a meaningful impact in the lives of others. We have struggled for years always trying to find a great deal on each product we buy to support our addiction to the outdoors. After years of turmoil, we felt we could change the outdoor gear industry by offering premium products for a great value while also working to eliminate poverty through funding microloans.

WE PARTNER WITH KIVA AND DONATE 10% OF PROFITS AS MICROLOANS TO HELP OTHERS AROUND THE WORLD!

Our company was founded on the principle of extending the wilderness to anyone who desires through providing premium quality products, that we ourselves use, affordably. We achieve this through our direct-to-consumer, fully cloud-based business model.  Ultralight backpacking, bouldering, peak bagging, and camping are hobbies, a mindset, and a way of life that we want to share with everyone. So grab your Hyke & Byke gear and go find your trail!
