Product Description

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


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.


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!

Hyke & Byke 625 Fill Power Hydrophobic Synthetic Sleeping Bag

Down-Like Warmth, Ultra-Lightweight, and Extremely Compact

Normally, synthetic insulation tests to be 300 - 400 Fill Power while our innovative, engineered Advanced Synthetic tested to have a loft equivalent to 625 Fill Power! This is a higher fill power than many down sleeping bags on the market!

This fill is “the closest synthetic insulation to natural down ever developed", stated by the Outdoor Industry Association.

This means that our Advanced Synthetic insulation boasts a higher warmth-to-weight ratio than most other synthetic sleeping bags. To top it off, it's both more compressible and durable giving you a high-end sleeping bag that will be your new "go-to" bag!

625 Fill Power Advanced Synthetic
