How To Choose A Dry Sack

How To Choose A Dry Sack

September 16, 2020

It can be hard to visualize what size Dry Sack would best fit your Zenbivy Bed. We've laid out a quick guide to hopefully make it a bit easier.

First, let us tell you a little more about Zenbivy Dry Sacks

  • They come in 3 different sizes: 7L, 10L, and 15L
  • They are compression compatible. Pair your Dry Sack with our Compression Caps to cinch it down even smaller!
  • Each Dry Sack is fully welded. What does this mumbo-jumbo mean for you? Well, most dry sacks sold today are sewn-and-taped and therefore vulnerable to leakage. Zenbivy Dry Sacks, on the other hand, are welded and will remain watertight throughout their life. 
  • Sounds like a duck, but our one-way valve dumps air faster than any other on the market. That's quick compression with a reliable water seal you can trust.
  • Our Dry Sacks are some of the lightest out there. Even the large 15L comes in under 3 ounces while still remaining watertight and durable.
  • They aren’t only reserved for sleeping bags though, of course. You can use them for your food, mess kit, clothing, toiletries... Anything you want to keep organized and dry, go ahead and stuff it!

Now, let's move on to choosing a size:

Below is a chart with our Bed* options and the size Dry Sack we recommend for each to ensure the best fit. Don't worry, with the recommended size there will still be room to throw in your Zenbivy Pillow and even a down jacket!

When paired with our Compression Caps, you can expect your Bed to compress down to roughly half the size of its recommended Dry Sack size. 

Which Bed Do You Have? Recommended Dry Sack Size
Zenbivy Bed 10º 15L Dry Sack
Zenbivy Bed 23º 10L Dry Sack
Zenbivy Bed 29º Synthetic 15L Dry Sack
Light Bed 10º 10L Dry Sack
Light Bed 25º 7L Dry Sack
Light Bed 40º Synthetic 7L Dry Sack


* A "Bed" is a quilt + a sheet. Mattresses are to be rolled up and packed separately.


      Common Questions:

      "Do I need to pair the Dry Sack with the Compression Caps?"

      That's totally up to you! Unlike all-in-one compression sacks, we made our Zenbivy Compression Caps an optional separate component because we understand it's all personal preference. Some people like to use them to keep their gear as small and compact as possible while others don't see a need to do so.

      For those longer trips where you need to maximize the space in your pack, simply add on the Caps and tighten the straps to instantly shrink it down. Less space space taken up by gear means more space for snacks!

      "Can I just stuff my Bed in the Inflation Sack and compress that?"

      The short answer is no. Let us explain why.

      If you're asking yourself, "What is an Inflation Sack??", an Inflation Sack is a dry sack included with our Light Mattress that allows you to easily inflate your mattress without having to blow into it.  

      While yes, you can absolutely use the Inflation Sack to store your Mattress, clothing, or other items, no, it's not ideal for compressing your Zenbivy Bed. Why? A main reason is that the air exit hole is on the bottom and the Compression Cap would cover it completely, preventing the air from escaping. Save yourself the headache. Our Zenbivy Dry Sack with the one-way, quick Air Dump valve on the side is the one you need in order to easily achieve a compact, tidy bundle of a Bed.

      "How do you fit a whole Zenbivy Bed into such a small bag?"

      Well, we can show you better than we can tell you! Here's a great video to demonstrate how we do it.

      "Is it okay to store my Zenbivy Bed in the Dry Sack?"

      When storing your Zenbivy, it's important to give it space. To protect the longevity of the down, you never want to store it fully compressed. Each Zenbivy Bed comes with a large mesh storage bag. When coming back from a trip, we'd recommend pulling your Zenbivy out of its Dry Sack as soon as you get home. If it's a nice sunny day, hang it up outside for a bit to air it out and let any moisture completely evaporate before storing it loosely in the mesh bag.




      Size Chart

      Unlike mummy bags, there is no thermal disadvantage to a larger size Zenbivy Bed because it is always free to wrap snugly around you. So bigger is always more comfortable and just as warm. If you are an "active" sleeper or have a "wide" sleeping position, you may want to size up to sleep naturally. When in doubt, size up.
