When buyers search for “koozie”, “coozie”, “stubby holder”, or just “can cooler”, they’re usually talking about the same basic product: a soft insulated sleeve that keeps drinks cold and shows a brand logo.
For B2B buyers, the spelling isn’t the most important question.
You care about:
What exact product type are we talking about?
Which materials and constructions work best for your brand and budget?
How to spec, customize, and source these items reliably from a Chinese factory?
How to bundle can coolers with insulated bags / cooler totes to increase average order value?
This guide answers all of that, from the perspective of a China OEM/ODM bags factory that also works with neoprene, insulation bags and promotional items.
1. “Koozie” vs “Coozie” – What’s Really the Difference?
From a language point of view:
“Koozie” – the most common spelling in the US
“Coozie” – a frequent misspelling / alternative spelling
Other terms: can cooler, can sleeve, drink holder, beer hugger, stubby holder (AU), drink cosy, etc.
From a trademark point of view, it’s more sensitive:
KOOZIE® (with capital K) is a registered trademark in the US, now owned by Koozie Group (Scribe OpCo, Inc.), originally created by Radio Cap Corporation (RCC) in the 1980s.
Over time, consumers started using “koozie” generically, similar to how people say “Kleenex” for any tissue, or “Thermos” for any vacuum flask.
For B2B procurement, the practical takeaway is:
In contracts & product specs, it’s safer to use generic names like “insulated can cooler”, “neoprene can sleeve”, “stubby holder”, or “drink holder”.
In marketing / SEO, you may still include phrases like “koozie / coozie” as search keywords (check with your local legal advisor if you are unsure).
So: spelling matters for legal & branding reasons, but for factory production, what really matters is the construction, materials and size spec, not whether you say koozie or coozie.
2. What Exactly Is a Koozie (Coozie) in Product Terms?
Structurally, a koozie is a soft, flexible, insulated sleeve designed to:
Fit tightly around a drink container (usually can or bottle)
Reduce heat transfer from hands, air and sunlight
Reduce condensation on the outside of the container
Offer a printable surface for logos, patterns, or brand messages
Typical construction:
Outer layer: neoprene, polyester, PU, or laminated fabric
Inner layer: same neoprene or foam for insulation
Base: open-bottom or closed bottom
Joining: flatlock stitching, zig-zag stitching, or glued seams
For a bag manufacturer like FY Custom Bag Factory, these are essentially mini neoprene or foam “bags” for drinks – the technical logic is very similar to neoprene lunch bags, insulated wine totes and cooler bags.

As a professional OEM/ODM factory, FY custom bag factory will then help you tune size spec and grading for each market.
4. Product Family: From Small Can Sleeves to Insulated Bags
Many buyers start with simple can coolers, then later expand into a full “cold drink” product family:
Single-can sleeves
Standard 12oz (355 ml) can
Slim can (seltzer, RTD cocktails)
16oz / “tall boy” cans
Stubby bottle holders (Australia)
Bottle & wine sleeves
Neoprene wine bottle sleeves
Champagne coolers
Adjustable bottle coolers with Velcro or zipper
Coffee / tea sleeves
Reusable neoprene coffee cup sleeves
Paper cup sleeves for large coffee chains
Cooler totes & insulated bags
4–6 can cooler bags
Insulated lunch bags for office, school
Insulated wine tote bags (1–6 bottles)
Soft cooler tote bags for beach / picnic
Cooler backpacks & duffels
Insulated backpack coolers
Large cooler duffel for travel, camping
For fybagcustom, this is where their bag OEM strength becomes important: once your brand is successful with simple can sleeves, you can upgrade into insulated bags using similar branding, colors and prints.
5. Materials: Neoprene, Foam, Fabric & Which One You Should Use

Neoprene and foam-based materials are frequently used for koozies worldwide because they combine insulation, flexibility, and low weight.
FY Custom Bag Factory has strong experience with neoprene bags and waterproof / insulation constructions, which transfer very well into koozie-style drink holders and cooler bags.
5.2 How to Choose Material by Use Case
Think in terms of where and how your customers will use the product:
Mass giveaway at events / concerts
Priority: low unit cost, high volume, bold logo
Recommendation: foam koozies or thin neoprene sleeves with 1–2 color print
Recommendation: 3–5 mm neoprene, full-color sublimation; matching wine totes or cooler bags
Retail / lifestyle brand
Priority: design, Instagrammable, works with other fashion pieces
Recommendation: neoprene or fabric-based, with custom cut shapes, zipper details, or matched handbags / totes
Corporate gifts / VIP sets
Priority: perceived value, gift packaging
Recommendation: leather / PU or thick neoprene, combined with insulated tote or cooler bag in a set
FY can work with neoprene, canvas, polyester, PU leather and more, plus special finishes like waterproof coating & TPU lamination, giving you many ways to align cost and brand positioning.

Because FY Custom Bag Factory is primarily a bag manufacturer, you can centralize all of these soft accessory items in one OEM partner instead of managing separate suppliers for koozies and bags.
8. OEM/ODM Process with a China Bag Factory
FY Custom Bag Factory has a typical OEM project flow that also applies if you add koozies and insulated cooler bags to your line.
Flexible options: sea, air, rail, express, based on your time & cost needs
Suitable for:
Amazon FBA shipments
Direct-to-warehouse delivery
Multi-country distribution
FY also emphasizes small MOQ (from about 100 pcs depending on design) and fast repeat orders, helping brands test new SKUs like koozies or insulated totes with lower inventory risk.
9. How to Choose the Right Factory for Koozies & Insulated Bags
When evaluating Chinese suppliers, look beyond only unit price.
9.1 Technical Capabilities
Ask:
Do they regularly work with neoprene, foam, insulation linings, waterproof laminations?
Can they handle both simple sleeves and more complex bags?
Which printing methods can they offer in-house or via stable partners?
FY highlights:
10+ experienced technicians with 20+ years in the bag industry
Advanced equipment such as CNC cutting & computer-controlled stitching
Rich options in fabrics and accessories (zippers, buckles, etc.)
These capabilities are highly relevant for consistent koozie fit and clean branding.
9.2 Design & R&D Support
Especially if you want a distinctive line, you need a supplier who can:
Interpret your sketches or AI designs into production-ready patterns
Suggest upgrades to bag structure, materials, function
Keep launching new styles to refresh your line
FY invests heavily in new designs and 100+ new bag designs per month, supporting continuous product development.
9.3 Quality Control & Scalability
Important questions:
How many QC steps are in place?
Do they have experience handling 500+ brand clients or large chains?
Can they scale from pilot runs (100–300 pcs) to large wholesale orders without quality drop?
In FY:
3 rounds of QC
Served 500+ brands in 20+ countries
Flexible MOQ from 50–100 pieces upward, with global shipping experience
These are the traits you want in a long-term koozie + bag partner.
Q1: Can I use the word “koozie” on my website or product?
Short answer: Many brands and consumers casually use “koozie” as a generic term, but KOOZIE® is still a registered trademark of Koozie Group in the US.
For safety, in legal/product documents use generic terms like “insulated can cooler” or “neoprene can sleeve”.
For SEO, many brands still use “koozie” in titles and descriptions — but it’s smart to consult a local trademark specialist if you’re unsure.
Q2: What container sizes should I cover for the US market?
Typical priority:
12oz standard can
Slim 12oz can (seltzer / energy drinks)
16oz tall can
12oz or 16oz bottle (with zipper)
Wine bottle sleeve for more premium programs
You can start with 2–3 key sizes and expand later.
Q3: What is a realistic MOQ for custom koozies from China?
With a factory like FY, MOQs from around 100 pcs per design are often possible for bags, and koozies can sometimes be grouped or combined depending on material and print.
For complex all-over prints or unique materials, MOQ may be higher due to fabric and printing setup.
Q4: Can I develop matching koozies and cooler bags in one project?
Yes – this is actually ideal:
Same color palette
Same pattern or artwork
Multiple SKUs for different price points (low-cost can cooler + higher-value cooler tote / backpack)
A bag-focused OEM like FY can manage all of this in one integrated production line, simplifying your sourcing and QC.

Even though FY’s core business is custom bags, the factory’s experience with:
Neoprene & insulated bags
Waterproof and TPU-laminated constructions
Multi-method printing and branding
Small MOQ and fast sampling
makes it very natural to extend into:
Neoprene & foam can coolers / koozies / stubby holders
