Things to consider before buying
If you’re looking for a compression sack that’ll help preserve your sleeping bag, there are some features you need to look for. So, here are the in’s and out’s of find the best compression sack for sleeping bag:
Compression Sack vs Stuff Sack
You’ve probably heard these two terms, however, they’re not the same thing. Not sure which one to choose? We understand. Here are the difference between a stuff sack and compression sack.
A stuff sack is similar in appearance to a compression sack. It’s a drawstring bag which allows you to store your personal belongings or camping equipment, however, it’s typically used for sleeping bags. They’re known to be bulky in size and build. In addition, they’re usually not waterproof, but rather are just used for storing items.
Compression sacks are specifically designed for storing sleeping bags in backpacks. It can be designed with or without waterproof features. It has a clothed lid that comes with adjustable straps that can be tightened to compress the size of the bag.
The best compression sacks ensure that your sleeping bag is kept dry. You’ll be able to backpack, camp, canoe–whatever activity it is–and your sleeping gear will be kept dry. Waterproof compression sacks achieve this with sealed seams and a dry bag closure.
Try to avoid purchasing a compression sack that is made of polyurethane-coated fabrics, as these are cheaply made and will not last long. For a proper waterproof compression sack, you’ll need to invest in it and that means paying a bit more.
Since they come in waterproof versions, canoers and kayakers will be able to secure their items while on open bodies of water. However, even if you’re not into the outdoors, business travelers can also use compressions sacks as they can easily fit their clothes into the small compartment.
You don’t need a compression sack that comes with a bunch of gadgets. You want it to be simple and do its duty. So, make sure your compression sack is made of lightweight material and is minimalistic in design.
Sometimes you’ll end up using your compression sack to carry other things, so you will want it to be as light as possible.
There’s no point in buying a compression sack if it won’t last you through one summer. You want a compression sack that’s durable and can withstand the elements, protecting what’s inside. In this case, durability comes with a price, so you do get what you pay for.
If you’re backpacking, you’ll want a compression sack that comes with either carrying or attachment straps. That way, you’ll be able to clip the compression sack onto your backpack. This can be an essential convenience depending on what you’re using your sack for.
Sleeping Bag Compatibility
Most compression sacks are compatible with any type of sleeping bag, however, there is a difference between synthetic and down sleeping bags.
Down sleeping bags are easier to compress than synthetically filled sleeping bags and typically need smaller sacks. You can use basically any dry sack for a down sleeping bag, however, if you’re in colder conditions, you will be needing a compression sack. In cold weather, you’ll need to reduce the volume of your sleeping bag.
Synthetic sleeping bags are known for being difficult to compress, therefore, they need a sack with higher volume. This mean, they’ll always be needing a compression sack; it’ll shrink the sleeping bag and allow for more space in your backpack.
