Party anywhere.

As the name implies, the Mountainsmith Sixer Soft Cooler holds a six-pack (bottles or cans) of your favorite brew (micro or 'merican), which is perfect for you and five friends, or less. However, you divvy up the drinks, they'll stay cold in the PE foam insulation and the melted ice won't leak out of the PEVA waterproof and seam-sealed liner. The Sixer comes equipped with a removable shoulder strap, and Mountainsmith even threw in a bottle opener to avert any last-minute disasters.

  • 150D ripstop fabric
  • PEVA waterproof and seam-sealed liner
  • PE foam insulation
  • Removable shoulder strap and bottle opener
  • Barrel top zippered closure accomodates bottles or cans

Daily Lunch Cooler

  • Familiarity: I've used it several times

I haven't had this product very long, but so far so great! I really like that the quality is obviously better than less expensive cooler bags that I've had in the past and that are more commonly around. I wholly trust Mountainsmith as a brand - I have had a couple of their other products for years and they are rugged. I like that this version of their cooler bag has a shoulder bag that I could use or remove if I wanted to.

All Purpose Beverage Caddie!

  • Familiarity: I've put it through the wringer

I've been using a Sixer for 5+ years now and it's run the gamut from carrying bottles of formula for my kids (when they were babies) to working as a lunch box to shuttling growlers (like I see in the other reviewer's images) to holding a six pack of cold ones for an apres beer following just about any day of recreation. Nothing like getting back to the car after a day in the BC, a MTB ride, etc. and pulling a cold one from the Mountainsmith Sixer (and don't forget it has a key chain bottle opener included). Oh...and you'll see in my photo, great for tailgating Red Rocks no less (about 5 miles from the Mountainsmith HQ in Golden, CO).

Keep it cold and safe in The Sixer

Keep it cold and safe in The Sixer

Contrary to its name, The Sixer can in fact carry more than a six pack of bottles(we think 15 bottles might be the record, but not recommended). Serving in more capacities than one, The Sixer is actually the perfect way to tote two 64 oz growlers. We have tried standard glass, plastic, and even double walled aluminum HydroFlask Growlers(highly recommended if you enjoy beer that is not lukewarm!).

Sitting side-by-side, you will be able to transport up to two full growlers safely and maintain their temperature at the same time. Go ahead and slip a few of your favorite coozies in the pocket on the back, they can be handy even if you are drinking out of a pint glass. Still want the safety of buckling your growlers into the backseat? No problem, just feed a seat belt through the large haul handle and smile, because you are going to have a refreshing beer in your backyard or at your campsite in the near future.

It's true.

  • Familiarity: I've used it once or twice and have initial impressions

Perfect sixer. It holds that and a little more, honestly. I've only used it once but it's easy to handle while I carry around the lake and on the move while I fish. Doesn't put too much weight on my shoulder and I use it as a cross body option. Keeps goods cool for several hours with the right pack and keeping it closed when you aren't using it.
