What kind of fabric is the 'UX10' mentioned in the bag description?
This question arises when looking through the specifications of an ultralight bag and encountering an unfamiliar fabric name, wondering about the actual material that realized the weight of 12g.
The UX10 used by Hegiorsak is an ultralight fabric based on Dyneema®, a high-strength fiber, made to significantly reduce weight.
The light figure of 12g immediately reveals the character of the bag[1]. Hegiorsak used UX10 and Dyneema® as the main materials for its 0.8L capacity ultralight mini pack[2][3].
Dyneema® is an ultra-high-molecular-weight polyethylene fiber that has a higher tensile strength than steel of the same weight, yet is light enough to float on water. UX10 is a high-functional fabric engineered to withstand tearing while reducing weight by combining these tough Dyneema fibers with a thin layer. The fabric itself absorbs almost no water and is resistant to abrasion, so it is primarily used in outdoor gear that needs to protect belongings with minimal weight.
hmmm, to achieve a weight of 12g while securing a 0.8L space, rather than giving up durability, a tough, cutting-edge fabric was chosen.

The specific water resistance rating or waterproof grade of the UX10 fabric has not yet been confirmed.
