Quick answers
How long does it stay cold?
Up to 72 hours of performance in a pre-chilled esky, lid shut, in the shade. Heat, a thin esky or opening the lid a lot will shorten it. Cold esky or your money back.
Will it fit my freezer?
Each 5kg bag is about 30 x 35 x 15 cm. The cubes sit loose in a soft mesh bag, so it shapes into a normal fridge-freezer drawer. Two bags fit one drawer.
How many bags do I need?
It depends on your esky size, the weather and how long you're away. Use the calculator on this page: pick your esky, trip and weather and it tells you.

REAL ADVENTURES. REAL ICE.
"My husband laughed when I ordered these instead of grabbing a servo bag. Took them out on the boat last weekend, snapper session, 35 degree day. Packed the catch straight on top and those fish were still firm and cold four hours later at the ramp. No wet slush, no melted mess, no $11 bag turning into water before the lines were even in. Bait stayed cold the whole session too. He hasn't said a word since. I've already told three of my girlfriends who fish. These aren't a gimmick - I just wish I'd found them two summers ago."
"I was fully ready to be disappointed again. Techni Ice that turned into slime, little blue bricks done by midday, servo bags half water before I even got to the campsite. Bought these mostly to prove nothing works. Friday arvo I loaded the esky with beers before a long weekend at the river. Saturday night, 38 degrees - opened the lid and the cans were still genuinely cold. Not cool. Cold. My mate kept grabbing beers out of my esky because his servo ice was a swimming pool by Saturday lunch. First time I've spent money on gear like this and not felt like an idiot."
"We do a lot of long weekends with the camper trailer and the VENTEK in the big esky combined with the cane cooler for the table has completely changed how we camp. Loaded the esky Thursday night, drove four hours Friday, cracked a cold one at 2pm that tasted like it came straight from the fridge. Didn't buy a single bag of ice the whole trip. I did the maths on the drive home - we've spent close to $800 on servo ice over two years of trips. That's more than what these cost. Kaz wants another set before our Christmas trip up north."
"Been burned by reusable ice before so I was sceptical. What got me with VENTEK is no gel, no chemicals — just frozen water in a proper sealed bag. First trip I packed whiting and flathead straight on top, four hours in the tinny in full sun. Every fish was still firm at the ramp. Usually I'm racing home before the slush ruins the flesh. This time I took my time, cleaned them properly, no rush. Texture on the fillets was noticeably better. My old man asked what I'd done differently. I ordered him a set for Father's Day and he rang three days later to say he's never going back."
"We do a charter a few times a year and the fish quality on the way home always bugged me. Paid good money for a great day and then servo ice is half-melted water by the time you dock. Brought two VENTEK bags on our last trip and the skipper commented on how cold my fish still were four hours after the bite. No water in the bag, no sloshing, just firm cold fish all the way home. Bec cooked them that night and said the flesh was the best from any charter we've done. I've already sent two mates the link. If you're still using servo ice for your catch, you're leaving quality on the table."
WHY OUR CUSTOMERS Love Us
"Finally stopped doing the Friday servo run."
I used to grab a bag of ice every single weekend without thinking about it. Five bucks here, eight bucks there. My mate showed me VENTEK and I haven't bought a bag since. Still cold on day three, no water everywhere, no mess. Should've done this years ago.
"Took it on a four day trip. Unreal."
Packed the esky Friday arvo, didn't open it until Sunday. Still had ice. We were gobsmacked. No soggy food, no flooded drinks, nothing. The boys all want one now. Best thing I've bought for the Ranger in years.
"My husband thought I was mad. Now he won't shut up about it."
I bought two bags before our Grey Nomad trip and my husband thought I'd wasted money. By day two he was telling everyone at the campsite about them. We've done three trips since and haven't touched servo ice once.
"Fits perfectly in the camper trailer freezer."
I was worried about the size but they stack perfectly. Freeze them at home, throw them in and you're done. No leaking, no gel, no drama. Paid for itself in the first month easily.

Frequently Asked Questions
Will it actually stay cold as long as you say?
+
Yes. The reason most reusable ice disappoints is that it's either a thin gel sheet, or it was frozen at a commercial freezer that runs close to 0°C. VENTEK is a 5kg bag filled with 360x cubes containing purified water and frozen in your own home freezer at around minus 18°C — the same temperature serious campers have been using homemade block ice at for decades.
Properly pre-frozen and packed in a good esky, the VENTEK 5KG Bag keeps things cold for up to 72 hours. Results vary depending on your esky quality, how often it's opened, and ambient temperature — but the core principle is sound. Frozen water at minus 18°C holds cold far longer than any thin sheet or bag of service station slush.
How is this different from Techni Ice or other reusable ice I've tried?
+
Completely different by design.
Techni Ice sheets use a gel fill that leaks through the seams as the product warms, leaving a slimy residue on your food and hands. Other products use drain plugs that fail. VENTEK has no gel, no drain plug, and no perforations. It's filled with purified water and sealed once at the factory. The failure modes you've experienced with other products are architecturally impossible with VENTEK.
That's not marketing — it's just how it's built.
Is $69.95 worth it when ice is only $5 a bag?
+
That's exactly the right question to ask. If you use your esky most weekends, you're spending roughly $10 to $20 per trip on servo ice. That's $520 to $1,040 a year, every year, forever. VENTEK Cubes pays for itself in the first few trips. After that, your ice is free. Over five years, a single bag saves you more than $3,000 at average usage. Buy it once, use it 1,000+ times, never stop at the servo for ice again.
Will it fit in my freezer?
+
The 5KG Bag is designed to fit in a standard household chest freezer or large upright freezer. If you're working with a caravan or camper trailer freezer this is perfect.
Does it leak?
+
No. There's nothing inside VENTEK that can leak. There's no gel, no chemical fill, no drain plug, and no perforations. It's a sealed bag of purified water — same principle as a homemade block ice, just purpose-built and factory-sealed. Once it's frozen solid, it's a solid block. As it thaws, the water stays sealed inside the bag. No mess, no residue, no contamination.
How long does shipping take?
+
All orders are dispatched from our Australian warehouse. Tracking is sent automatically within 24 to 48 hours of your order being placed. Standard delivery typically takes 2-4 Business Days depending on your location.
Is VENTEK an Australian brand?
+
Yes. VENTEK is Australian-owned and operated. We ship from Australia, our support team is in Australia, and the brand was built specifically for the way Australians use their eskies — long weekends, fishing trips, road trips, camping. We're not a dropship operation and we're not going anywhere.
What's inside the bag — is it food safe?
+
VENTEK Reusable Ice is filled with purified water and made from BPA-free plastic. There are no gels, no chemicals, and no artificial additives of any kind. It's food-safe and designed to sit directly alongside your food and drinks in the esky, the same as any block ice would.
Can I put it directly in my drinks and beverages?
+
Yes. VENTEK is filled with purified water and made from BPA-free plastic with no gels, no chemicals and no artificial additives inside. It's completely food-safe and designed to sit directly in your esky alongside your food and drinks — same as any block of ice would. It won't contaminate your drinks, leave any residue, or affect the taste of anything it touches. Just freeze it, drop it in your esky or drinks bucket, and you're done.
