Solves the problem of back stuffiness without adding weight.
The appeal of UL backpacks is, after all, their overwhelming lightness and simplicity. However, in summer or during long periods of activity, it's not uncommon to feel "a stuffy back" or "pain from cargo pressing against the back."
LUNA PROJECT's "Back Air Mesh Pad" is an item that simply solves such weaknesses inherent to UL backpacks. By creating a space between the backpack and your back and securing a path for air circulation, it significantly reduces stuffiness.
Weighing in at a lightweight 70g range, it maintains the UL style while also improving cushioning and carrying comfort. This upgrade part enhances back comfort by a notch, not only for hiking but also for bikepacking and daily use.
