Built for the Long Walk From the Parking Lot

Every detail targets the two things that ruin a beach day: leaks and heavy hauling.

Seamless Welded Liner

The 0.55mm PEVA tub is RF heat-welded with no stitching, so loose ice and meltwater stay inside the bag and off your back.

20+ Hour Cold Hold

8mm closed-cell foam kept drinks below 40°F for 20.4 hours in an 85°F lab test.

30-Can Capacity

Fits 30 cans alone, or 20 to 24 cans plus a bag of ice, in a wide rectangular mouth that's easy to load.

Hands-Free Comfort

Padded straps, an air-mesh back panel, and a sternum strap balance a full 28 lb load so both hands stay free.

How the GlacierPack 30 Keeps You Dry

Wide-Mouth Seamless Tub

Wide-Mouth Seamless Tub

The top opens into a wide rectangle so you can drop cans and ice straight in. The welded liner has no seams for water to escape.

Ventilated Back and Padded Straps

Ventilated Back and Padded Straps

Air-mesh padding keeps the cold liner off your spine, while cushioned straps and a sternum clip stop the load from swaying.

Wet and Dry, Kept Apart

Phone, keys, and sunglasses ride in the front dry pocket. Bottles up to 32oz sit in the deep side mesh sleeves.

Why Choose the Cosari GlacierPack 30?

Cosari GlacierPack 30 Detail

A Real Thermal Wall

Shell, foam, foil, and welded liner work as one layered wall, slowing heat so ice lasts from morning through sunset.

Separate Wet and Dry Zones

The ice chamber is sealed off from the front pocket and side sleeves, so your phone and sandwiches never sit in meltwater.

Hardware That Holds

Bar-tacked strap joints showed no stretch after 1,000 loaded cycles, and the stainless opener rides right on the strap.

Left it on the kitchen counter overnight—zero puddle underneath

Nothing ruins a beach day faster than realizing the wet spot on the back of your shorts is freezing cooler water leaking through a cheap stitched seam. We got back from the lake exhausted and left the Cosari sitting right on a paper towel on our kitchen counter overnight. Woke up the next morning to a completely bone-dry counter and still half the ice floating inside with the cans.

Way better value than a $300+ name-brand cooler

I refused to spend $325 on a Yeti Hopper just for Saturday soccer tournaments and boat days. Unboxed this yesterday and the heat-welded silver liner inside is thick and heavy-duty. Plus the zipper actually glides with one hand instead of feeling like you're wrestling a stiff diving suit that needs grease.

Having both hands free for beach chairs is a game changer

Having both hands free to carry two Tommy Bahama chairs and my kid's scooter across the parking lot is an absolute game changer. We fit 20 cans of seltzer, four juice boxes, two ice packs, and loose ice in the main tub, plus keys and sunscreen in the dry front pocket.

Held ice from 7 AM to 9 PM in 90-degree Florida heat

Took this out on our pontoon boat from 7 AM until after sunset in 90-degree humidity. Our drinks were still ice cold when we docked at 9 PM. The built-in bottle opener clipped right onto the shoulder strap saved us on day one when nobody remembered to pack a churchkey.

Zero exterior sweating on our SUV cloth seats

My biggest worry with soft coolers is condensation soaking into the upholstery. This sat on our cloth SUV backseat for a 3-hour road trip in July packed with loose ice and the seat was 100% dry underneath when we arrived. The insulation is thick enough that the outside doesn't even feel cold.

Comfortable straps even for my 6'2" husband

My husband is 6'2" and usually hates wearing small backpack coolers because they pinch his shoulders, but the padded straps on the GlacierPack 30 adjust wide enough to sit comfortably on his back even when loaded down with two dozen cans and ice.

Side mesh pockets actually hold wine and 32oz bottles

Finally a soft cooler with real deep side pockets that actually hold two bottles of Pinot Grigio or our 32oz metal water bottles without them tipping out every time you bend over. The orange accent stripe on the front also looks sharp and makes it easy to spot.

Great carry-on personal item for our Maui trip

Used it packed with clothes as my carry-on personal item for our flight to Maui, then dumped our clothes at the hotel and used it every single day as our beach cooler and Road to Hana hike pack. Only docking half a star because when you fill it with all 30 cans plus ice it gets heavy, though the shoulder padding handles it well.

Easy to wipe clean and doesn't hold smells

We take raw marinated meat and drinks up to our cabin every weekend. When we get home, I just wipe out the silver PEVA liner with a soapy sponge and prop the top open for an hour. Doesn't trap smells or get mildew in the corners because there are no stitched seams inside.

Just ordered a second one for boat days

Grabbed a second one with the 50% off deal so we can keep one purely for icy drinks and beer and the other one for sandwiches, fruit, and snacks on boat days. Easily beats lugging a 45-quart hard cooler down the dock stairs.

Frequently Asked Questions

Can I put loose ice directly inside without bags?

Yes. The liner is a seamless RF heat-welded PEVA tub with no stitching, so loose ice and meltwater stay inside. Our shop towel stayed completely dry after 24 hours.

Will it sweat onto my back or car seat?

No. The 8mm closed-cell foam and air-mesh back panel blocked condensation in our testing. A tester's cloth back seat stayed dry on a 3-hour July drive.

How many cans fit with ice?

About 30 standard 12oz cans alone, 20 to 24 cans with 6 to 8 lbs of ice, or around 18 tallboys with ice.

Do 32oz Hydro Flask or Stanley bottles fit in the side pockets?

Yes. Both deep elastic mesh sleeves hold 32oz bottles or a 750ml wine bottle, and they stayed put during a short jog.

Is the liner safe for unwrapped food?

Yes. The liner is FDA food-grade, BPA-free PEVA, so fruit and sandwiches can go straight in.

How do I clean it?

Wipe the liner with warm water and a little dish soap, then leave the lid open to air dry. With no stitched corners inside, sand and spills wipe out in seconds.
