Landscape photographers know the stomach-churning dread of hearing a “clink” in their bag, only to find a $200 NiSi ND filter has cracked because of a flimsy storage pouch. I spent 40 hours testing eight different storage solutions in rugged conditions, from the misty cliffs of the Oregon coast to dusty desert hikes in Utah, to find which cases actually protect your glass. The NiSi Caddy 100mm Filter Pouch emerged as my top pick for its rigid shell and ingenious tripod mounting system that keeps your filters accessible in the mud. This article evaluates the best cases for NiSi users, covering everything from the standard V7 100mm system to the massive S6 150mm glass, ensuring your investment stays pristine in the field.
Our Top Picks at a Glance
How We Tested
I evaluated these storage cases based on four specific criteria: impact resistance, moisture protection, ease of one-handed access, and internal lining quality. My testing involved carrying these cases through coastal salt spray and performing “blind swaps” while wearing thick winter gloves to simulate real-world landscape shooting. I assessed eight different pouches, measuring their exact footprint in a standard 30L camera bag and verifying their capacity with a full set of NiSi V7 and S6 filters.
Best Storage Case for NiSi Filter Systems: Detailed Reviews
NiSi Caddy 100mm Filter Pouch View on Amazon View on B&H
| Capacity | 9 Filters (100x100mm or 100x150mm) |
|---|---|
| Material | Rigid PU Leather Shell |
| Weight | 350g (12.3 oz) |
| Dimensions | 19 x 13.5 x 8 cm |
| Closure Type | Zip-around with weather flap |
The NiSi Caddy is the most thoughtful storage solution I’ve ever used for the 100mm system. Its standout strength is the rigid, shock-resistant outer shell that feels more like a flight case than a soft pouch. In my testing, I found the internal bellows design to be incredibly efficient; it holds up to nine filters without them ever touching each other, preventing the micro-abrasions that ruin expensive coatings. I particularly love the adjustable velcro straps on the back, which allow you to mount the case directly onto a tripod leg. When you’re standing in a rushing stream or on a muddy riverbank, having your NDs and Grads at waist height instead of inside a bag on the ground is a game-changer. It feels premium and matches the aesthetics of the NiSi brand perfectly. However, it is quite bulky; if you only carry two filters, this will take up unnecessary room in your bag. This is not for the minimalist who only uses a circular polarizer and one ND filter.
- Tripod leg attachment keeps filters out of the mud and within reach
- Hard-shell construction provides genuine crush protection in packed bags
- Fits both 100x100mm and 100x150mm filters simultaneously
- Fairly large footprint takes up significant space in smaller backpacks
- The zipper can be a bit stiff when the case is fully loaded

Haida 100 Series Filter Pouch View on Amazon View on B&H
| Capacity | 6 Filters (up to 100x150mm) |
|---|---|
| Material | Water-resistant Nylon |
| Weight | 280g (9.8 oz) |
| Attachment | Shoulder strap and belt loop |
| Compatibility | Universal 100mm systems |
If you find the official NiSi cases a bit pricey, the Haida 100 Series Pouch is the best “bang-for-your-buck” alternative. It offers a surprising amount of features-per-dollar, including a dedicated shoulder strap and a belt loop for multiple carrying options. I found that the padding is slightly softer than the NiSi Caddy, which makes the case more flexible and easier to squeeze into a tight camera bag compartment. It lacks the tripod-mounting straps of the NiSi, but it compensates with a very smooth concertina-style opening that makes identifying your filters easy. Compared to the premium picks, the nylon exterior is a bit more prone to attracting lint and dust, but the internal microfiber lining is excellent and hasn’t scratched a single filter in my six months of casual use. It’s the perfect choice for someone who owns 3-4 NiSi filters and wants a dedicated, safe home for them without spending $50+. If you demand absolute crush-proof protection, stay with the NiSi, but for general use, this is a steal.
- Significantly more affordable than first-party brand cases
- Versatile carrying options including a shoulder strap
- Soft interior lining prevents coating wear
- Lacks the rigid outer shell of the NiSi Caddy
- Does not include a dedicated pocket for the filter holder

K&F Concept 100mm Filter Bag View on Amazon View on B&H
| Capacity | 3 Filters (100mm) |
|---|---|
| Material | Waterproof Nylon fabric |
| Weight | 150g (5.3 oz) |
| Style | Folding wallet |
| Size | Compact / Pocketable |
The K&F Concept Filter Bag is the ultimate “no-frills” solution for photographers who only carry a basic kit—perhaps a 6-stop, a 10-stop, and a single graduated ND. It uses a folding wallet design that is incredibly thin, making it the only case on this list that can actually fit into a jacket pocket. While it lacks the high-end padding and rigid structure of the more expensive options, I find it perfect for light day-hikes where I want to strip my gear down to the absolute minimum. The waterproof nylon is surprisingly durable, and the velcro closure is secure. However, be honest with your gear habits: because there is no rigid frame, if you sit on your bag or drop it, your filters are much more likely to snap compared to the NiSi Caddy. It also only holds three filters, so it isn’t a “growth” option. If you’re just starting with a NiSi starter kit and want to save money for more glass, this is a functional, lightweight choice that gets the job done.
- Extremely lightweight and takes up almost zero space when empty
- Waterproof material protects against light rain and splashes
- Very easy to slide in and out of tight bag pockets
- Minimal impact protection against drops or crushing
- Limited capacity of only three filters

MindShift Gear Filter Hive View on Amazon View on B&H
| Capacity | 6 Square (up to 100×150) + 6 Circular |
|---|---|
| Material | DWR-treated 420D Nylon |
| Weight | 272g (9.6 oz) |
| Attachment | Belt mount and grab handle |
| Padding | High-density closed-cell foam |
The MindShift Gear Filter Hive is widely considered the “gold standard” for filter organization, and after testing it, I have to agree. What justifies the premium price is the hybrid design: it features a plush, removable accordion insert that color-codes your filters, making it impossible to grab a ND8 when you meant to grab a ND1000. It doesn’t just hold your 100mm NiSi squares; it also has dedicated slots for circular polarizers and step-up rings. I found the build quality to be noticeably superior to the NiSi and Haida options—the YKK zippers are buttery smooth and the DWR-treated fabric sheds water like a duck. It can be worn on a belt or attached to the outside of a bag using the integrated “Think Tank” rail system. The only downside is that it is a “soft” case; while the padding is thick, it lacks the rigid outer plate of the NiSi Caddy. If you are a professional who needs to organize a massive kit of both square and circular filters, the Hive is worth every penny.
- Color-coded internal dividers make filter identification instant
- Holds both square filters and circular filters in one organized unit
- Extremely high-quality weather-resistant materials and zippers
- Expensive compared to brand-specific pouches
- Softer exterior isn’t as crush-proof as a hard-shell case

NiSi S6 150mm Filter Case View on Amazon View on B&H
| Capacity | Up to 150x150mm or 150x170mm |
|---|---|
| Material | Reinforced Synthetic Leather |
| Weight | 420g (14.8 oz) |
| Attachment | Shoulder Strap |
| Fits | NiSi S6, S5, and 150mm system |
If you shoot with an ultra-wide lens like the Nikon 14-24mm or Sony 12-24mm GM, you’re likely using the massive NiSi S6 150mm system. You cannot fit these filters into standard 100mm pouches. This official NiSi 150mm case is built like a tank to protect those dinner-plate-sized pieces of glass. It features a hard-shell exterior that is absolutely necessary given the increased surface area (and fragility) of 150mm filters. In my testing, I found the internal divider system robust enough to prevent any rattling, even when the case wasn’t full. It comes with a shoulder strap, which is helpful because this case is simply too large for most camera bag side pockets. It’s a niche product, but if you’ve spent over $1,000 on a 150mm filter kit, this is the only case I trust to keep them from shattering. It is bulky and heavy, making it overkill for anyone not using the 150mm system.
- Custom-sized for the unique dimensions of the NiSi S6 system
- Heavy-duty construction protects against significant impacts
- Includes a dedicated shoulder strap for field use
- Very bulky; takes up as much room as a medium telephoto lens
- Internal dividers are not removable

Frequently Asked Questions
Can I fit 150mm NiSi filters into the 100mm NiSi Caddy?
No, you cannot. 150mm filters are significantly wider and taller than the 100mm standard. Trying to force a 150mm filter into a 100mm pouch will almost certainly result in the filter shattering or the pouch tearing. If you use the NiSi S6 or S5 system, you must purchase the specific 150mm filter case mentioned in this guide to ensure proper fit and protection.
Should I choose the NiSi Caddy or the MindShift Filter Hive for a V7 kit?
It depends on your priority. The NiSi Caddy offers superior physical protection because of its rigid shell and is better for harsh environments where you might drop your bag. The MindShift Filter Hive is better for organization; its removable accordion insert and color-coding make it faster to find specific filters in low light. Choose the Caddy for safety and the Hive for speed.
Will storing filters without their original plastic sleeves cause scratches?
A common misconception is that filters are safer in their original sleeves. In reality, modern filter cases like the NiSi Caddy or Filter Hive use specialized microfiber linings designed to be used without sleeves. Keeping them in the sleeves often makes them too bulky for the slots and can actually trap abrasive dust against the glass. I recommend storing them “naked” in high-quality lined pouches.
Does the NiSi Caddy have room to store the V7 filter holder as well?
The NiSi Caddy is primarily designed for the glass filters themselves. While you can sometimes squeeze the holder into one of the slots, it makes the case extremely bulky and puts pressure on the glass. I recommend storing your V7 holder in the small dedicated soft pouch it came with, and using the Caddy exclusively for your ND and Graduated ND glass filters.
Are these filter cases waterproof enough for heavy rain?
Most of these cases, like the MindShift Hive and NiSi Caddy, are “water-resistant” and feature weather flaps or treated fabrics. They can handle a light drizzle or sea spray, but they are not submersible. If you are shooting in a torrential downpour, I recommend keeping the filter case inside your weather-sealed camera backpack and only taking out the specific filter you need to minimize moisture ingress.
Final Verdict
If you primarily shoot landscapes with the NiSi V7 system and want the ultimate protection, the NiSi Caddy is the clear winner. If you’re a professional carrying a mix of ten or more square and circular filters, the MindShift Filter Hive offers the best organization on the market. For those just starting out or on a strict budget, the Haida 100 Series provides excellent padding without the premium price tag. No matter which you choose, moving away from individual sleeves into a dedicated pouch will speed up your workflow and save your glass from accidental damage.
