NiSi Caddy II Circular Filter Case - Portable Waterproof Filter Pouch

In this review of the NiSi Caddy II circular filter case, the bottom line is simple: photographers who carry several circular filters and need compact, rugged protection will appreciate this pouch. It is designed to hold up to eight filters up to 95mm and prioritizes protection and quick access, making it a practical pick for landscape shooters and travel photographers. The single biggest reason to buy is the combination of a shock-resistant hard shell and a microfiber-lined interior that keeps filters from scratching while stored together.

Key Features

• Compatibility: Holds up to eight circular filters up to 95mm and fits common types like CPL, UV, ND and adapter rings for broad gear coverage.
• Premium protection: Shock-resistant hard shell plus waterproof nylon and a sealed zipper guard filters from impacts, moisture and dust.
• Interior design: Microfiber-lined individual compartments keep filters separated to reduce the risk of scratches and scuffs during transport.
• Accessibility: Wider opening and individual pouches allow faster access on location, and smart bands help identify filters in low light.
• Portability: At about 5.45 ounces the pouch is lightweight and includes a metal clip to attach to a bag or belt for hands-free carry.
• Practical extras: Reinforced structure resists crushing and an exterior accessory pocket holds small items like adapter rings or cleaning cloths.

Who It's For

This case is aimed at photographers who travel light but still need a small set of circular filters close at hand: landscape photographers working in the field, on-location portrait shooters, and hobbyists who switch filters often will find the NiSi Caddy II especially useful. Its lightweight build and clip make it convenient for day hikes and urban shoots.

Those who should look elsewhere include photographers who carry many thick or step-up ring-mounted filters, rotating filter systems, or larger-than-95mm filters, since thicker frames or rotating filters may take extra space and reduce the total capacity below eight.

Pros & Cons

No. The Caddy II is designed for standard circular filters and adapter rings up to 95mm, not square or rectangular filter systems.

Is the case fully waterproof?
The exterior uses waterproof nylon and a sealed zipper to guard against moisture and dust, but it is not intended for full submersion.

Will rotating or thick filter frames fit eight slots?
They can fit, but thicker or rotating frames may occupy extra space and reduce the total capacity below eight.
