The Mayfly 14L Cooler
The Mayfly 14L Cooler
The Lightest Backpack Cooler Ever
The Mayfly is the smaller of our two coolers. An independent test conducted by Outdoor Life found that it took 55 HOURS for 7lbs of ice to melt, tied with the industry leader's backpack cooler (you know who we mean... did we mention our cooler is 6 TIMES lighter?)

Frequently Asked Questions
How long will it hold ice?
30 Hours+!
Truth is, it depends on conditions(110 degrees outside or nice spring day), but we think of Monti as your "All Day" cooler. In tests we've conducted it kept temperatures ice/water below 40 degrees for over ~36 hours in a 70 degree room.

How do you use the stuff sack?
The stuff sack is built into the cooler itself. The exterior zippered pocket IS the stuff sack. Simply reach into the pocket, grab a big handful of the body of the cooler and start to turn the cooler inside out, pushing the body of the cooler into the inside out pocket you've created. The cooler's convenient stuff sack is seamlessly integrated into its design, making it easy to store and carry.
What is the return policy?
Monti Guarantee: Changed your mind? No problem! Just let us know and you can return your unused cooler for a full refund within the first 30 days of purchase.
Which size should I get?
If you're unsure, consider the Shasta, as it is the most versatile.
The simplest way to decide is by looking at the capacity. The Shasta will never be "too big" because the roll top design ensures that it is compressed down to match the size of what you have inside it. (ie if you have only 6 cans in the cooler, you will roll the top down further). So really it comes down to your needs. Picnic with friends? Shasta. A simple bottle of wine and a few water bottles or a lunch sack for work? The Mayfly is perfect.
