The Sea to Summit Ember Quilt is full of 850+ UltraDry Goose Down in 2022. That is the top quality down used on any Sea to Summit sleeping bag or quilt. It isn’t solely light-weight but it surely additionally has good water resistance qualities as they use the water repellent down.

Once you buy a Sea to Summit Quilt you’ll get a certificates from the Worldwide Down Feather Laboratory (IDFL). This certificates will state precisely what Responsibly Sourced Down was utilized in your Sea to Summit Ember quilt.

Once I opened my new Ember Quilt the down was a barely increased fill of UltraDry down. The said 850+ down is the minimal customary that Sea to summit have dedicated to place in your Ember Quilt. Generally that batch of down could also be a bit of increased however by no means decrease. Not all corporations present this data.

Let’s check out how the Ember backpacking quilt is made with the options such because the Internal and Outer Shell materials, baffles, foot field, draft tubes, the way it connects to the sleeping pad and climate resistance.

Outer Shell material

The exterior face material of the Sea to Summit Ember Quilts are constructed from an ultralight 10 Denier Ripstop Nylon which is coated with an up to date PFC-free DWR end. The DWR coating stop drops of water from getting into the quilt by permitting them to bead and run off the face material. The material could be very gentle but additionally very sturdy.

When testing the Ember quilt I poured numerous water onto the quilt to check the standard of the material and DWR coating. It exceeded expectation on the climate resistance, however extra on that later.

General, the material seems to be fairly sturdy sturdy however I did have a difficulty with the buttons that connect to the mat straps. Extra on that later.

Internal material

The Sea to Summit Ember quilt makes use of a 7D inside ripstop nylon material. It has an excellent really feel and seems to be fairly sturdy.

Climate resistance

As talked about earlier than, I did pour a whole lot of water onto the quilt to simulate being caught in rain or having a leaking tent. The quantity of water I utilized in testing was considerably extra that you’d count on in regular use. In actual fact, greater than you’d count on in excessive conditions.

In the course of the testing the material and DWR end did a tremendous job of conserving the down dry. A small quantity received in by the stitching but it surely had completely no have an effect on on the lofting capability of the UltraDry down which repelled the water.

General, this bag can be appropriate to sleep outdoors on a moist night time when the condensation comes down and makes every part damp. This quilt is not less than equal to or higher than some other backpacking quilt available on the market for climate resistance.

Disclaimer: I don’t advocate that you simply pour a few bottles of water over your backpacking quilt to check the water resistance, however if you happen to did, you’d discover it does an excellent job.

The Ember EBII and Ember EBIII use boxed baffles in a mix of vertical and horizontal baffles to stop down shift whereas sleeping at night time. The Ember EBI makes use of the ultralight sewn by baffles to maintain weight to a minimal.

General, there’s not a lot to fault with the baffles and down fill within the quilts. They work as they need to. I might have preferred a bit of extra down stuffed into every baffle however solely as a result of I personally like an overstuffed quilt. The hand hotter pockets and neck collar are very effectively filled with down.

Testing the Ember Quilt

The Ember Quilt collection options both a completely enclosed foot field or a drawcord cinch wire foot field. The cinch wire permits the foot field to open and shut as wanted. The Ember EB I and Ember EB II have the drawcord system and the Ember EB III has the totally enclosed baffled foot field.

I favor the totally enclosed baffled foot field on quilts to be used in colder temperatures. However after I need a quilt to be used in hotter climate the cinch wire on the foot field is the desire. Thus, I like how the colder rated Ember quilt has the enclosed foot field. And the nice and cozy rated Ember to be used on hotter climate has the drawcord closure.

The foot field can slip over the top of your sleeping mat or the entire of the foot field can sit above the sleeping pad. Each work good. However the backside attachment straps are too small to make use of.

General, there’s nothing to fault and the foot field system works effectively on all of the Ember Vary. It does the job of conserving your ft heat. The enhancements made over time guarantee a a lot better closure system.

Draft Collar

There isn’t any hood on the Ember quilt which is regular on all backpacking quilts. Hoods don’t do effectively on quilts and not one of the prime manufacturers together with Sea to Summit use a hood. However and not using a hood you want an excellent system in place to stop chilly drafts getting into across the neck.

The Sea to Summit Ember passes the draft take a look at through the use of hand heaters inside the highest of the bag which can be utilized to position your arms in and pull the bag tight round your neck. The hand heaters are beneficiant in dimension and look like overstuffed with down as they’re very effectively packed. It additionally has a drawstring on the neck space to tighten the highest of the bag to scale back draft from getting into. The neck collar additionally seems to be beneficiant in dimension and effectively filled with down.

General, the Sea to Summit Ember Quilt does an excellent job of conserving you heat.

Ember Quilt Sleeping Pad Attachment System

If I could be vital of 1 factor in regards to the Sea to Summit Ember Quilt it’s the sleeping pad attachment straps and the system it makes use of. Let me clarify.

The Ember quilt makes use of press studs to connect an adjustable strap to the quilt. The adjustable strap runs underneath the sleeping pad to maintain the quilt in place and maintain you heat if and when wanted. The straps do an excellent job of stopping drafts and it does an excellent job or conserving the quilt in place. There are additionally a number of methods you need to use the quilt and fix it to the sleeping pad. When the nights get colder and it’s essential to use the attachment straps the system is inferior to some others available on the market.

Firstly, let me say that if you’re utilizing the Ember quilt as a blanket on hotter nights with it simply wrapped over you with out utilizing the attachment straps, the quilt excels as a backpacking quilt. However when it’s essential to use the straps it runs into some potential points that may very well be higher however lets perceive how the attachment straps work.

To connect the straps you firstly must carry the mat and quilt so the straps run underneath the mat. And if at any time through the night time it’s essential to make any changes, it’s essential to get out of the quilt, into the chilly air, and alter the straps beneath the mat. There simply doesn’t appear to be any simple solution to make changes through the night time.

You possibly can simply simply undo the press stud to take away the strap if it’s essential to vent some warmth if you happen to get hotter through the night time. And possibly you possibly can attain underneath the sleeping pad, discover the adjustment buckle and loosen or tighten it, however due to the place it’s positioned it isn’t that straightforward. It’s simpler to get out of the quilt to do it.

The press studs can be utilized to connect collectively to make use of the quilt just like a mummy type sleeping bag. The quilt is sufficiently big to have the ability to do that, nevertheless, I recommend you don’t use the quilt like this. Once I did it, at some stage throughout testing I should have put stress on the press stud and the material across the press stud broke. Was the stitching across the press stud not adequate or was I too tough with the quilt. Unsure. Both manner the press stud pulled off the material.

However not all is misplaced. As a quilt with out the straps, the Ember Quilt excels as among the best within the class of ultralight backpacking quilts. On the subject of heat. it’s also among the best at school. When the straps are hooked up and also you don’t must make changes the quilt can also be among the best at school. If Sea to Summit can give you higher quilt attachment straps this bag can be one of the best available on the market.

Stuff Sack – Compression And Packability

The usual Stuff Sack equipped with the Ember Quilt is sweet and there’s no want for anybody to contemplate upgrading to anything. It’s light-weight and could be compressed very small with the facet straps.

As talked about above the stuff sack will compress the bag to a smaller dimension. Confer with the Specification chart for detailed comparisons.

The inner sizing of the Ember Quilt elevated a few years in the past to provide extra shoulder room. Once I examined the Ember Quilt I had loads or wiggle room inside. Throughout colder nights I used to be capable of put on a winter grade Down Jacket and nonetheless had sufficient inside room.

When sleeping on my again or facet the quilt was roomy and I had a number of room to toss and switch as wanted.


When testing the bag I discovered the temperature score to be true to these said by Sea to Summit. Although the quilt is just not EN / ISO examined I discovered them correct. As a chilly sleeper I used to be nonetheless capable of keep heat.

The Ember quilt additionally has new QuiltLock System to permit the quilt to be buttoned to any Sea to Summit Sleeping bag. This has the power to extend the efficiency of a sleeping bag and backpacking quilt. It may possibly even flip a 2/3 season sleeping bag right into a winter sleeping bag. Simply clip the highest press stud onto the sleeping bag and wrap the quilt over the sleeping bag.

Throughout gear testing of the Sea to Summit Sleeping Baggage and Backpacking Quilts I attempted the QuiltLock System. I mixed the Sea to Summit Spark SPII Sleeping Bag with the Sea to Summit EBIII quilt utilizing the QuiltLock system.

The loft on this method was superb. I’m unsure what temperature score it will have been, however I think I might have been very comfy in temperatures right down to round 0F / -17C. I’m positive at these temps I might have had an excellent nights sleep. Unsure if that’s correct, that’s simply my hypothesis. I used to be unable to check this method totally on the time of publishing as I haven’t been in areas with these extraordinarily low temperatures but.

retailer your Ember Quilt

The Sea to Summit Ember comes with a Lofting bag included along with your quilt. The lofting bag is just not as massive as I would love. Once I bought my first Sea to Summit Sleeping Baggage a few years in the past it got here with a really massive cotton lofting bag. I might have preferred to see a bigger lofting bag not less than twice the scale of the one equipped with the quilt. It’s not a lot but it surely may very well be a really small enchancment that might change sooner or later.
