Description & Condition
ROSIÉ is a brand that prioritizes the physical well-being of musicians and is dedicated to creating an environment where they can focus on their music.
Furthermore, its philosophy is based on fairness for all involved parties and the goal of sustainable long-term relationships.
For example, workers in the factories that manufacture ROSIÉ products are never forced to work for unfairly low wages.
In this way, all transactions are based on the premise of fair trade.
This includes not only relationships with factories, but also literally all stakeholders, such as delivery companies and end users.
This model is a gig bag released as the second product in the ROSIÉ brand.
Its most distinctive feature is the AGS (Anti Gravity System), which makes the weight of the load feel lighter.
This system uses spring-like movement in the shoulder straps when walking, making the perceived weight feel 40% lighter*.
[*Pressure measurement test conducted by the testing institution BOKEN.] The test method involved attaching the left and right straps of an AGS-equipped backpack containing a 6kg sandbag to a test machine, lifting it 30cm from the machine, and allowing it to free-fall. The results showed that the non-AGS backpack produced 198N, while the AGS-equipped backpack produced 113N, a reduction of approximately 43% (test conducted June 2022, test number 35022002283).
AGS is a highly valued technology originally used in business bags.
This is the world's first application of AGS to a guitar gig bag.
Furthermore, during development, we sought opinions from backpack experts and discovered that many conventional gig bags have problems with the placement of the shoulder straps.
In this state, the center of gravity shifts away from the back, causing the bag to sway significantly and leading to fatigue.
Therefore, the shoulder straps were designed so that the center of gravity fits snugly against the back, eliminating unnecessary movement.
By incorporating AGS technology, positioning the shoulder straps optimally, and thoroughly eliminating unnecessary parts,
these measures significantly reduce the burden on the body. If you get tired while traveling to rehearsal studios or live venues, the quality of your performance will suffer.
This product is designed to eliminate that fatigue and create an environment where musicians can concentrate more on their music.
It's the best gig bag for working musicians who often carry their instruments on their backs.
