Includes 2 ice packs and an insulated mailer to help keep your liquid yeast cold during transit.  The Insulated Mailer option is a great way to extend the length of time your ice remains cool!  These special envelopes contain self expanding foam, which creates a form-fitting container that protects and insulates liquid yeast.  This upgrade includes the Insulating Envelope and 2 Ice Packs.

This option fits a number of yeast vials, pouches, or cans, and is made from thick foam insulation.  Because different yeast take up different space, each producer will fit a different quantity in this mailer.  See the chart below for what quantity of what yeast will fit inside.

Yeast Producer / Brand Quantity that will fit in Insulated Mailer
White Labs 10
Imperial Yeast 3
Wyeast 3
GigaYeast 3
Omega 2

To purchase, simply add however many Insulated Mailers will be needed to contain however many yeast are in your cart.

Please Note!  Any additional yeast will be shipped outside of the mailer.  This option includes ice, and no additional ice needs to be purchased.

It works
This mailer will keep your MLB at a proper temperature for 2 days at least in the mail. Works well, no problems.

Just the thing for mail delivery
My 2 packs of WLP802 arrived in two days and the yeast was still cool when I opened the package. It is large enough for more than two packs of WLP.

Sides exposed
If you order liquid yeast with the packaging, I suggest you don't do in the summer (which is what I did). It's just a sandwich of insulation with the sides offering nothing. The ice pack was completely melted when it got to me. Again, this was July or August when I ordered, but that's why I ordered the insulated pack.

Be Careful
If you find that your yeast(s) are shipping from a different address, as mine were, make sure it's only a 2-day delivery window. My delivery window was 5 days, but only revealed after payment...the yeast was probably impacted given my slow ferment, even with a starter. I re-learned an old lesson: buy fresh, local yeast.

What’s cooler than being cool?
What’s cooler than being cool? Ice cold! Alright alright alright alright.

That’s what the yeast say as you keep them alive with this necessary ice pack.

great option
I've seen people whine about getting warm yeast, but anyone with common sense would realize the purpose of this isn't to get the yeast cold, it's to keep the yeast as viable as possible in transit. The yeast wasn't cold when I got it but after building a solid starter, I got a very nice Marzen and munich helles from the lager yeasts that were shipped in this packet. I'm going to submit them for competition and will be using one for a homebrew club duel...will update with my results.

Keep you Yeast Alive
Must have if you live in a warm region. These work well and will keep you yeast safe until it arrives.

Add more ice packs
I would have given them a higher rating but I live in the south where temps get in the upper 90s and triple digits pretty regularly. By the time it makes it to me it's nearly ambient temp. I haven't had any issues with the yeast viability from any of the packs I've purchased but would like them to still be cold. Maybe add a few more ice packs if you live in the southern states.

Got the Job Done
Ordered 2 packs of Imperial Yeast in the insulated envelope. I also paid for an additional ice pack to stuff it full. Yeast arrived nice and cool, close to fridge temps I'd guess. I did place a larger order, so this was inside an additional box with grain, etc. That may have helped. For reference, I live in the Central Valley in California, within the 1-day shipping radius. Weather during transit was in the 90's.
