The Shasta 23L Cooler
























The Shasta is our flagship cooler - the biggest, best Monti Cooler we make still folds down tiny to fit any adventure! 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 their cooler is 6 TIMES heavier?)
• Leakproof liner- Seam-welded leakproof liner to prevent leakage.
•Dimensions:
Cooler Open: 20"H x 10"W x 6.5"D

The Original Puffy Cooler™
Recommendations: Use the roll-top for peak performance and comfort. We also find the product performs best with ice packs rather than ice in higher humidity environments if you are concerned about condensation.

— Denise F.
"Absolutely love it! It’s not bulky and it’s easy to carry even when it’s full. It definitely keeps things cold and I love the fact that I can tuck it away when I’m not using it. I was so happy I waited for the sale and used it over the weekend. I can’t wait to take it when I go to Hawaii."
— Susan K.
"We’re absolutely loving this backpack cooler, and my husband, especially, was thrilled using it on Father’s Day. It’s thoughtfully designed for travel, the lightweight, puffy jacket style insulation folds into its own stuff sack, making it ultra-portable and easy to toss in our or carry‑on"
— Linda C.
"Love that the cooler is leakproof and that it folds back into itself! Perfect cooler for many situations, especially traveling by plane somewhere when a cooler is needed. This fill fit great in a suitcase when not in use."
— Davis S.
"10/10 cooler right here y’all. Light as a feather and small as a mouse when condensed, the Shasta makes traveling with a cooler a breeze! Also doubles as a chilled pillow at the beach."
