At the beginning of your backpacking trip, you probably have the best intentions to keep your pack organised, but it’s not always easy to cram your gear back in your bag when you’re in a rush to meet a train or catch a flight.
The Sea to Summit Ultra-Sil Compression Sacks enable you to compress your gear down to a third of its size without adding extra weight to your pack. You can pack down anything from down jackets to synthetic sleeping bags, as there are a range of sizes for gear of all shapes. These sacks are constructed with tack reinforced stress points for extra strength, are made from siliconised fabric for durability and water resistance, and are ultra-lightweight - which makes them ideal for outdoor adventures.
As for usability, these products feature four straps for even compression all over, a slippery finish for easy packing, a flip top hood to prevent straps tangling, and a grab handle for easy carrying. Also, a great bit of gear to have on hand for hiking or camping trips where you’ve got limited room - a lifesaver for the space-conscious outdoorsperson.

Size for Sea to Summit Quest II Regular1 answer
Hi, just wondering what size you would recommend for the sea to summit quest II regular sleeping bag that is advertised on your site - https://www.snowys.com.au/quest-qu2-right-zip-wmns-sleeping-bag-1c. I am thinking medium ~ 15L will do. Thanks!

G'day Brett,
The Large size Ultra Sil Compression Sack will suit the Quest Qu2 sleeping bag.

Size for J&H Dandelion1 answer
G'day, any ideas on which size would suit for a J&H Dandelion down bag?
Mitch - Coburg(6 years ago)
G'day Mitch,
Thanks for getting in touch, sounds like you've got a great sleeping bag on your hands, I've heard great things about them over the years! In terms of size, unfortunately, it's really hard to say, do you have a current storage sack? If so I'd try and compress it as much as I can so you can do a rudimentary volume measurement and chose from there. I would guess you'd probably need around the Medium size (14L capacity - 4.5L compressed) or the Large (20L capacity - 6.7L compressed).

What size for a carryon?2 answers
Hi - i am looking to buy this to compress everything soft which I would put into a carryon sized bag for travel. It seems as though the XL would be ok, but without seeing it in person I'm worried it might be too big. I suppose what I am asking is, if i get the XL and fill it entirely with clothes etc, would it compress down to a size that would fit into a carryon sized bag? Thanks!
Anne - Melbourne(6 years ago)
Gday Anne,
I've just looked into this for you - sorry to be vague, but it really depends on what and how much you put in there. The bag will compress to a minimum of 10L if the contents allow you to squish it down that far.
For example, if you’ve got bulky jumpers and jackets in there, you might find it more difficult to get it down to the 10L volume simply because the fabric isn’t designed to be compressed like that.
Apologies we couldn’t give you a solid answer Anne, but it’s a little tricky to guess without knowing how much and what you would be packing.
Emily - Snowys(6 years ago)
Thanks Emily! Your response did help in that I should think more about the maximum size since I can't assume that everything will compress down to the minimum size.

Caribee Snow Drift Sleeping Bag1 answer
Hi - I've just bought a Caribee Snow Drift sleeping bag - What size Compression sack would I need?? Thanks
Kez - Lake Macquarie(6 years ago)
G'day Kez,
The Caribee Snow Drift Sleeping Bag can be a touch bulky at times and when it comes to compression sacks, I always recommend getting a slightly bigger one because you can always compress it more to get it as small as possible. With that said, I would say that you'd be best off getting an XL Sea to Summit Ultra Sil Compression Sack.

What size?1 answer
Hi Snowys,
I have a Kelty Cosmic 20 sleeping bag and wondering if you could help me figure out what size compression sack would I need?
Ray - Melbourne (7 years ago)
G'day Ray,
We're not familiar with the Kelty Cosmic 20 sleeping bag, but I've done a little research online for you and I'd say that if you went for a Large size which is 20L that can be compressed as small as 6L, you should be okay.

Which size is best for a double sleeping bag?1 answer
I have a double sleeping bag made from two Coleman Dexter Point -5C Sleeping Bags. I'd rather store it as a double for convenience. What compression bag would best fit?
Jess - Maroochydore(7 years ago)
G'day Jess,
I've just gone and done a bit of physical testing in store. The biggest Sea to Summit Ultra-Sil Compression Sack is 30L. While it is a bit of a squeeze to fit both bags in, it is possible and then from there, you can compress them a bit further to bring the overall size down. Let me reiterate, it's not an easy fit, but if you can squeeze the air out and compact it as much as allowed, it is a possible fit.

Are these water proof?1 answer
Hi team, Can I ask if these bags are water proof? Or, water resistant even? If I had my sleeping bag in this, would it stay dry inside a backpack?
Jitendra - Sydney(8 years ago)
G'day Jitendra,
The fabric on the Ultra Sil compression sacks is waterproof, however the opening and seams would be a weak point if this bag was submerged in water.
If you just need to keep of a splash of water - this bag will do, but if you're going to encounter a lot of water (e.g. kayaking, canoeing) then you may want to go for the Sea to Summit Compression Dry Sack which is fully waterproof.
