Perfect match for the Quarter Dome Air hammock
I just received my REI Quarter Dome Air Underquilt the day before I was going camping so I put it to the test. It's well made and the ideal companion to the Quarter Dome Air which I was using this weekend. Here's what I liked and didn't like about it. Temperature It was between 90 degrees and 60 degrees and it kept me nice and warm. It's supposedly rated to 30 degrees and I didn't have a opportunity yet to test that out. Conditional Pass. Attachment Because of the design and being made for the Air I was able to attach it in about 30 seconds. All 4 ends have pairs of shock cords (one of which had a plastic clip) and it was a simple matter of clipping them together. I was initially worried that the clips wouldn't hold but the connection is positive enough that I no longer have that worry. On the two long sides there are toggles that mate perfectly with the loops in the hammock. This keeps the hammock from drooping both lengthwise and widthwise and doesn't require long shock cords. Pass. Adjustment At both ends there are shock cords with cord locks that you use to take up the slack and keep the UQ snug to the ends and to prevent wind from coming in either end. It took seconds to adjust and if you use it on the same hammock this is a one time adjustment. Pass. Color The UQ comes with one side orange that nicely matches the Air and the other a very dark blue. You can hang it either way. I was wanting more stealth this time so I went with the dark side out. Pass. Access Because of how the toggles are placed to attach the UQ to the Air, they are located right where the mesh pouches are -- both the one outside and the split one inside. As a result, one of these will be blocked a bit depending if you are using the bugnet or not. I was using the bugnet so the outside one was blocked although I was able to place my headlamp in there with a bit of difficulty. No blocking the split one inside. Partial Fail. Pack Size Because it's a synthetic UQ it takes up a fair bit of room compared to a down UQ but reasonable for the rating. The material is very durable and could have been made of lighter weight material but wouldn't save too many grams. Pass. Value For the cost it's a pretty decent synthetic UQ from a reputable company with an excellent return policy. The insulation isn't name brand but there seems to be a sufficient amount and it doesn't seem like it will shift any. You could DIY one cheaper but this seems like a good value. Pass. Conclusion If you have an Air hammock this is a no brainer. Get it. I could find almost no downside to it. Sure, I might eventually make a DIY down version which will pack smaller and the obstruction of one of the pockets is a minor annoyance but if you like the Air you will like this underquilt.
Great quilt for the price!
I bought this to use with my grand trunks single hammock. The cord was not long enough and this product was obviously meant to be used with REI's hammock which is a different animal. That being said nothing a couple loops of paracord couldn't fix. Once I lengthened the attachments I was able to snug up the quilt perfectly under my hammock. I camped at about 10,000 feet above sea level in Colorado in mid September and it kept me decent. I wasn't cold but I could've been warmer. I paired it with a 20 degree mummy bag I used like a top quilt. I'm not sure what the tempature was but it was snowing so I have to assume it was 32 degrees or below. I know the quilts rated at 30 degrees so I would say it did its job just fine once I modified it to fit my hammock.
Performed as expected.
Light weight, easy to take on and off. Kept my underside warm. Works well as a blanket, too.
4 stars
I give it 4 stars very easy to attach it is definitely made for the air hammock which I bought them as a pair and tried on a 37 degree night with my 40 degree ultra lite sleeping bag and my uninsulated Klymit static V... I would say it's temp rating is more around the 40 degree range this is the first underquilt I've ever tried and it does help keep the butt and upper body warmer a noticeable difference but I did start to get somewhat chilly in the morning... if this is your first underquilt I do recommend it for the price and quality but if you plan to go out in winter or below 30 degrees I suggest practicing with the setup before your out on a trail to make sure your warm and comfy...
Not good for cold weather
This underquilt is a great match for the Quarter Dome Air in that it perfectly fits and is easy to use together. It also gets pretty small when I put it in a 10L compression stuff sack. On warmer nights this would work great. My main issue is that I was freezing cold on a ~40F night. I had a 20F rated quilt on top of me but could not sleep until I put a jacket on to keep me from getting cold from underneath, and even then could not sleep that well despite being very comfortable otherwise in the hammock. Another nitpick is that one of the attachments directly covers the pocket on the outside of the hammock, so you have to choose between one or the other.
Good, not great
This year for Christmas, my husband and I bought two of these. Figuring they could be a good alternative to spending $150+ on a different brand of underquilt. Let me break it down a couple ways. Cost: very good, especially with it's on sale. I don't feel like I've wasted my money. Especially when you compare it to how expensive other companies underquilts are. However, for good reason. More expensive ones offer more warmth, and versatility. Pack size: packs down nice and tight, the synthetic down does pretty well at competing with duck, or goose down. Obviously it could be smaller. Suspension: if you don't own an REI hammock it not ready out of the bag, but worry not. All you need is some shock cord, and a couple of S biners. And I found 4 or so feet to be good for attacking it to an 11 foot hammock. So 8 or 10 feet cut in half for both sides, leaving room to adjust. Warmth: here is where it gets lower marks. First of all, I fault REI for not providing some sort of temp rating. After digging around online, I found that it was a 40 degree under quilt. I'll kindly disagree. This underquilt needs just a fraction more isolation, to really keep you warm. I found a fair bit of cold butt syndrome with this, and if it had just a pinch more loft, it'd be just fine. Seeing as how this is my first underquilt, I'm happy with it, but I know I could be happier. I didn't mind providing my own suspension, that's half the fun. What I do mind, is having a cold butt when it's only 45, or 50 degrees out.
works great but..
I bought this to replace the poorly designed Eno underquilts. I typically spend up to 80 nights a year in a hammock and was excited to find that REI was producing a larger, rectangular shaped under quilt that would allow proper angled sleeping positions. Last night was my first run and in 45 degree weather with a very light sleeping bag it performed well with my ENO double nest. HOWEVER, non REI hammock users beware this is not easily compatible with NON-REI hammocks. it lacks a bungee system that stretches far enough to connect to the carabiners included with my hammock to clip onto the straps. I had to loop both cords per end around the base of the rope that extends from my hammock to the carabiner, and its a very tight fit. Because of this its a buyer beware, you might need to get creative situation. That being said it is much more functional then the tightly cut, symmetrical ENO quilts that don't allow coverage of both your shoulders and feet if you sleep sideways like we all are learning to do in hammocks.
Hammock Underquilt completes the Quarter Dome Air
This is a great and comfortable hammock and the underquilt completes it and makes temperatures down to the low forties (Farenheit) comfortable. I hope REI doesn't discontinue this hammock and quilt combo, it's light and helps you get a good night's sleep on the trail.
Not Warm Enough
This quilt is well-made and complements the Quarter Dome Air great, but I don't think the 30° rating is inaccurate. It was around mid 30's (my water didn't freeze) That I used it with the matching 2017 Magma sleeping bag and my backside was uncomfortable cold all night long. Perhaps I should have used a pad, also.
3 Season design; quality control issues
The quilt is rated as a 3 season design. One of the toggles on the quilt was offset by about 8 inches, making it impossible to properly attach to the loop on the hammock. Will recommend to friends but with the above cautionary notes.
