Product Description

Our Half Gallon Jumbo Flask is the ultimate bachelor party accessory! Consistently one of our top-selling products, it’s constructed of high quality stainless steel and holds 64oz. of your favorite libation. Bust it out during your bachelor party — or display it in your home bar or office (it’s a real conversation starter). The only real downside is the trouble you’ll have trying to sneak this baby into the movie theater or opera.

  • Holds 64oz. (THAT'S A HALF GALLON!)
  • High quality, brushed finish stainless steel.
  • Measures 7-7/8" x 11-5/8" x 1-3/4".
  • Limited lifetime manufacturer warranty.


Are there any restrictions for using the Jumbo Flask?

This jumbo flask is designed to be used with alcoholic beverages. Do not use for beverages with acid content, such as fruit juices and cordials. Do not keep alcohol in the flask longer than a period of three days. Only refill the flask when you are about to use it again.

What are the care instructions for the jumbo flask?

To clean, rinse the inside with soapy water. We also recommend doing the process before the first use. Always empty the flask after use and rinse thoroughly before filling again.

Thousands of Satisfied Grooms and Groomsmen

Since 2008, we’ve been the go-to site for personalized, unique groomsmen gifts and wedding tips for men. We’re also proud to be the original groom’s gift registry.

I reached out to The Man Registry on a Saturday, just 7 days before my wedding, asking for help with my groomsmen gifts. I heard back within an hour and was able to get 8 personalized coolers in just 3 days. Ordering was easy and the quality was top notch. Would highly recommend The Man Registry!

The Man Registry is phenomenal. The customer service is exceptional - seriously. You send an e-mail and a person (a friendly one at that) actually responds within an hour. Also, gift options are diverse and plentiful so you'll be able to find what works best for you.
