Had the cb26 a few weeks now and can say it’s fantastic, loaded my coolbag on Friday morning with all my food and drink with 2 frozen 1 litre bottles of water. Just got home and still have ice in my water bottle 55 hours later. Well worth the money in my opinion.

Regarding size it will be personal preference but for me the cb15 is ample for a 24 and Im happy to go back to the car/shops to replenish if I was doing a longer session but the majority of my fishing is overnighters so the only real time I use the CB26 is if Im doing longer sessions or when Im with the family camping (More mouths to feed) or its a god send as an example next weekend when Ill use it at camp bestival with the family and will be out all day and we can load it with beverages and will be sufficient for the 4 of us for the day - The choice is yours ultimately regards what works best for you

There are so many factors that effect performance of coolers as an example I have an Anker Everfrost 58L electric fridge for when we are off grid abroad etc and its a beast and costing nearly £1000 and even on a unit of that size and value the stated running times differ from the actual performance dependant on where its stored, what I place in it, how I pack it, even if I leave it in the sunlight as an example but the biggest factor is what is the initial temperature of the item I am placing in it and I think thats the same for all cool bags.


I personally dont feel the need to add Ice or blocks to my CB15 as I tend store things that are already cold and I also keep my plunge lid in the freezer which is a great edge Ive found and my food and beers will still cold easily long enough

In regards to the ratios the general consesus is 2:1 Ice/Food

A quick Google search shares the info below

Mass:
A 2:1 proportion provides enough freezing power to drive temperatures down and keep them below the safety threshold of 40°F (4°C).Block vs. Cubes: Solid block ice or frozen gallon jugs melt much slower than loose ice cubes because they have a lower surface-area-to-mass ratio. Use blocks at the base and fill gaps with cubes.

Practices for PackingLayering:
Put a solid layer of block ice at the bottom, followed by your pre-chilled or frozen food, and top it off with more ice or frozen water bottles.

Separation: Keep raw meats near the bottom and store a separate cooler for drinks if you plan to open it frequently.

P.S Thanks for those who have placed orders

Robert, a question I'm surprised no ones asked re capacity.

Yeti etc suggest a ice/block ratio to food, do you have a similar ideal ratio, it'd give a better idea for 'usable' volume
If you do are they different for say 48hr v longer duration.

Watching you're vid on testing brought back memories of blast chiller/chiller/ poly box validation cycles I used to do in the medical sector.

Better to have more room and not need it than not have enough room

That is very generous, nice one👍

I was being tongue in cheek about the beer cans but it is very handy to know the small one can take 6kg of bait.

I cant make up my mind what size to get.

Just to add the bag is not only great for keeping things cool, they are also great at keeping things warm for the times when you leave the lake to pick up a takeaway its great

I’ve just got into the office and loaded a cb15 with kilo bags of sticky - we got 6k in the cb15 and 10k in the cb26

There’s a video that’s been posted on our socials showing this as well @jagprolite

I have both sizes.
I can honestly say they are pukka.
I don’t just use them for fishing.
Been using one smaller 1 since it came out and it really does keep your items cold.
Personally I did find the small version too small for 48hours.
But now the bigger size is perfect.
I use mine 2/3 times as week and they really do keep my food & drinks chilled.
I originally used some slim line freezer packs to help keep the internal area cold but have changed over to use gel freezer bags as they are slimmer and I can slot them more easily between cans and food packs.

Thanks for the positive comments, the questions and suggestions which I’ll take on board and I’ll gladly do my best to answer your questions in due course, we’ve tried to share the answers to most the questions people had regards capacity (which invariably was how many beers will it hold, how long does ice stay frozen for as an example) but I’ll be sure to share how many kilos I can fit in the cb15 and cb26 shortly - but I’d urge people to look at the marketing tests we did which sells the product for me itself

Regards popping in to see me - I split my time between prolite explorer (behind the scenes upstairs) visiting the trade and at Cotswold - I will start a seperate thread at some point about Jag/cotswold/prolite and our USP’s in a crowded market rather than derail this thread about the cool bags but I’m really keen to engage with our consumers so anyone visiting the shop in Luton feel free to ask for me and I’ll gladly come down and chat / share ideas / feedback etc

I truly appreciate how fortunate I am to be working in an environment I’m passionate about with people who have the same values and passion as me and im excited for what lies ahead.

I’ve learned a lot from this community along the way so feel free to ask any questions and I’ll come back to you as quickly as possible and I look forward to hearing other users comments

Ive got all the speero cool bags and they are ok but they wont be anywhere near as good performance wise as the latest cotswold coolers.

Just ask AI, let’s use a standard can of Coke.

A standard 330 ml Coke can is approximately:

* Height: 115 mm
* Diameter: 66 mm

Your cool bag’s internal dimensions are unlikely to exactly match the external dimensions, but using the dimensions you provided as an estimate:

* 300 × 210 × 220 mm
* Volume: 15 litres

Best-case packing (upright cans)

* Along the 300 mm length: 4 cans (4 × 66 = 264 mm)
* Along the 210 mm width: 3 cans (3 × 66 = 198 mm)
* Height 220 mm: 1 upright layer (115 mm high)

Total: 4 × 3 = 12 cans

You would still have around 105 mm of vertical space above the cans, which is useful for ice packs or food, but not enough for a second upright layer.

If stacked horizontally

With careful packing, you could fit:

* 2 cans along the 220 mm height (2 × 66 = 132 mm)
* 3 cans along the 210 mm width (3 × 66 = 198 mm)
* 2 cans along the 300 mm length (2 × 115 = 230 mm), leaving some room, or potentially more with alternating orientations.

Theoretical packing works out to around 18 cans, but in a soft-sided insulated bag, the lining, rounded corners and zipper reduce usable space.

Rob, For the more dedicated anglers, Instead of loads of beers in the cool bag advert how about a practical picture of how much bait/kilo bags the COTSWOLD AQUARIUS | CB15 COOL BAG could hold. 😉

Good luck Rob 👍🏻

Ive just bought the smaller CB15 version but it hasnt arrived yet. Ive got a coupe of yeti coolers and they are brilliant and the cotswold one out performed the yeti by a long way in the tests so I have high hopes for it when it arrives.

I can only see cotswold going in the right direction now Jag own them and are designing the luggage now so I can see my wallet getting a lot lighter.

It’s on their website ?

Model

Internal dimensions

Capacity

CB15

300 × 210 × 220 mm (30 × 21 × 22 cm)

15 litres

CB26

380 × 280 × 260 mm (38 × 28 × 26 cm)

26 litres

They sound really good though like all things will be goodvto see some independent reviews.

What would be good is to give us a rough an idea of how much food you can put in them as opposed to just cans of beer!😂

Afternoon lads,

For years Ive been on here saying how much I love CA and Jag having been a huge fan, imagine my pleasure when I was fortunate enough to land my dream job as brand manager just over a month ago overseeing the brands and helping to drive the business forward so wanted to share this before commenting.

The cool bags have been flying out, we really cant make them quick enough - one of the best things about them is the marketing and research we did which no doubt you would of seen on our socials which demonstrates the performance of the bags against all of our competition including Yeti.

They are truly a brilliant piece of kit and before I worked here I have and still have Titan bags from costco, trakker and aqua cool bags, ridgemonkey cool box, Yeti Hopper tote bag, Igloo and even two anker solix everfrost for when Im off grid and so I'm well versed in finding a good one

I am very keen to hear feed back from other users and would be happy to answer any questions on the products

Thanks for the support
