How To Choose A Compression Sack — Buying Guide

How_To_Choose_A__Compression_Sack

When choosing the best compression sack, it’s easy to get overwhelmed by so many options. Remember, however, that the most popular choice isn’t necessarily the best compression sack. Carefully considering aspects like type, materials, strap system, and carrying capacity will lead you to the perfect sack for your trip.

Types of Stuff Sacks

The three most common types are high-compression sacks, waterproof dry sacks, and stuff sacks. All three have different features that give them advantages and disadvantages when compared to others.

High compression sacks

These are designed to save as much space as possible. They should have a high-quality compression system to press down your gear into the smallest potential size. They are generally made of durable materials (like ripstop nylon) and can be used to pack clothing and sleeping bags efficiently.

Waterproof Dry Compression Sacks

As the name suggests, these stuff sacks are waterproof, making them ideal for travel. Designed specifically for wet outdoor conditions, these dry bags can protect your gear and keep it dry throughout the trip. They often feature a roll-top closure and sometimes float if dropped in water.

Stuff Sacks

This is the most basic option – the type you usually get by default when buying a sleeping bag. They are great for storage, but won’t compress the gear as much as a high-compression bag. They usually have a drawstring closure (meaning they’re not waterproof), so they are best used in warmer climates.

Materials and Construction

When choosing a stuff sack, try getting a model made of rip-stop materials – they will protect the bag from accidental tearing. The most common option is here nylon, but other material blends exist that add even more strength to the sack.

Also, it’s a big plus if the material is waterproof (like a waterproof bag), so your sleeping bag won’t get soaked if you get caught by unexpected weather. Lastly, the backpacking stuff sacks should be made of lightweight materials, without adding unnecessary bulk.

Bag Weight

Stuff sacks for backpacking should always be lightweight. They are meant to help you organize by minimizing bulk, not add to it. As we’ve mentioned previously, the material used is the deciding factor here and needs to be lightweight.

You want your top rated stuff sack to have weight only when it is full of your gear. A good rule of thumb is to get a bag that weighs only 20% (or less) of the gear inside and its total packing weight.

Compression System

Depending on the model and manufacturer, stuff sacks for backpacking use different systems for compressing your gear. When discussing this, it’s important to notice how the sack closes on top and which system it uses on the sides to compress the content inside.

Top closure

Two different closure methods can be found in compression bags – a roll-top and a drawstring closure. Roll-tops are great for getting the air out and work like a dry sack to keep the geat inside dry. We would advise that you get this type if you expect wet conditions.

Drawstring closure uses a simple drawcord and gives you quick access to the gear while on the trail. These tend to be less powerful then pressing down – they will hold your gear in but won’t get rid of the extra air.

Side straps

Regardless of the closure, high compression stuff sacks have a piece of fabric (a hood) going over the top that connects to the webbing straps or cords on the sides. When buckled, these exterior straps can be pulled on the tabs to force out any extra air and keep the sack compressed (until the straps are released).

Another great option is the air purging system. It uses an air-permeable fabric that allows extra air to escape while you are pressing on the bag, and doesn’t allow it back in until you open it. This system often delivers a very compact and reliable compression, but it is also fairly expensive.

Waterproof Design

Waterproof compression sacks are meant to keep your sleeping bag dry even if they are accidentally submerged. This can be very useful if you need to cross a river on your trail. To be considered waterproof, it needs to have roll-top closure and be made from the non-permeable materials with sealed seams (much like a dry sack).

The performance of waterproof sleeping bag compression sacks varies from one product to the other. Of course, products with a higher waterproof rating tend to cost more too. While there are big differences between water-resistant and waterproof, sometimes even a water-resistant model can ensure a dry sleeping bag.

Portability and Convenience

Because of their nature, backpacking compression bags need to be highly portable. You are using them to make packing more convenient, so a bulky design should be avoided. Top rated stuff sacks are lightweight and collapsible, allowing you to bring them along on any adventure.

Carrying Capacity (Volume)

Most stuff sacks are measured in liters and come in all imaginable sizes. This makes it possible to find the exact size you need – from a model that fits only a cell phone and some valuables, to one that’s big enough to line your entire backpack.

For a sleeping bag, it needs to be roughly the same volume (or slightly larger) as the one you got with the bag. This way you’ll be able to get the bag inside and compress it fully. If it’s too small, you’ll have difficulties putting the bag in. If it’s too large, you won’t be able to compress it all the way.

  • While holding it with your hands (so it doesn’t unroll) start pushing it into the bag
  • Make sure you’ve pushed it all the way down and, if a piece is sticking out, push on it to get it inside
  • Tighten the top (drawcord or roll top), close it, and put the hood on
  • Instead of pulling on the straps right away, we advise that you first press on the top with your bodyweight
  • While pressing on the bag, pull on the straps and tighten them equally from every side (doing it like this will fully compress it without ripping the bag in the process)
