In late July 2026 Muji’s water‑repellent “Ripstop” backpack, priced at ¥4,990, became a bestseller in Japan, with reviewers highlighting its lightweight ripstop nylon construction, large opening, mesh pockets, side bungee strap and effective water‑repellent coating. Strong demand led to frequent sell‑outs online and on social media.

A week later, Muji introduced a smaller water‑repellent Ripstop shoulder bag priced at ¥3,990. The 23‑liter, 20 kg‑capacity bag features adjustable side draw‑strings, mesh pockets and a side zip for quick access, and is praised for its simple design and versatility for travel, gym visits and day trips. Reviewers note the material is thin and may tear if handled roughly, adding a caution to the otherwise positive reception.

Together the snapshots show Muji expanding its water‑repellent bag line and maintaining consumer interest across product variations.
