Why It’s Different
🚿 Compact & Complete: All-in-one hot and cold mixer valve, hose, and showerhead — engineered to fit tight spaces without compromise.

🔗 Quick-Connect Convenience: Attach or detach the hose in seconds and stow it in the included ripstop pouch. No rattles, no clutter.
🛠 Durable & Lightweight: Braided nylon hose resists kinks, stays flexible, and weighs less than metal — perfect for off-grid setups.
