Compact, leakproof Sixer Soft Cooler keeps a six-pack cold for trails, tailgates, and weekends away

What Our Gearhead® Experts Are Saying:


"The Sixer nails that perfect balance between portability and insulation. It’s burly enough for day trips, kayak camping, or post-ride beers but light and compact enough to toss over your shoulder. The waterproof liner really works—no soggy car seats, ever."


Built for backyard hangs, road trips, and off-grid picnics, the Mountainsmith Sixer 12L Soft Cooler is our go-to for keeping drinks cold and adventures chill. Its PE foam insulation locks in cold temps far longer than typical soft coolers, while the waterproof PEVA lining and fully sealed seams ensure melted ice stays contained—not dripping in the car or tent.


The Sixer’s barrel-shaped design easily fits six bottles, twelve cans, or even two growlers, making it perfect for small crews and solo missions alike. A removable shoulder strap provides carry comfort from the trailhead to the beach, and the rugged P600D PVC shell resists scuffs and snags from years of use. Whether it’s a park picnic or a paddling trip, this cooler packs serious cooling power in a travel-friendly size.

The cooler Yeti couldn't make

Familiarity:
I've used it several times
Size Bought:
12L

20 years ago, I inherited a yellow Mountainsmith cooler. Well, inherited is probably the wrong word. It just showed up at my house and I have no idea where it came from. To be honest, I didn't even know the brand name of it. I just referred to it as my yellow cooler. It soon became my go-to cooler for weekend kayak camping trips as it was one of the few larger coolers that could be shoved into my narrow hatch openings. More than that, ice stayed ice for much longer than in those smaller 6-pack coolers. Eventually, that cooler gave up the ghost and I had to replace it. I looked into all sorts of other coolers. The Yetis are good but they're too rigid and have way too much wasted insulation space that I can't afford in my hatch. So I kept searching...remember...I didn't even know the yellow cooler was a Mountainsmith. But then, searching on Backcountry I saw the anvil logo and it all came back to me. It was a Mountainsmith! Now, I will say that the new version is a tad bulkier and thicker than the old yellow one. But it still stuffs into my hatch pretty easily and keep stuff cold for longer than you'd expect. I love it.
