Phantom™ Spark 28° F / -2° C Sleeping Bag (Regular) is rated 4.4 out of 5 by 9.
Rated 1 out of 5 by from Leaking Down!! Was sold this bag and told it would last for years. Now down is leaking out of the seams even with careful and proper use. Warranty is now saying its normal. I have had this issue with one other bag in all my years and that company recognized the issue and fixed it properly, I guess I will have to go back to that company.

Rated 5 out of 5 by from Phantom Spark Sleeping Bag I am a professional Guide working in the New England states. I bought a Phantom Spark this spring and have used it all summer in the White Mountains of New Hampshire. It has gone over Mount Washington with me and everywhere else. I love this bag for summer. It is very light weight and packs small. It has kept me warm and comfortable all summer in the mountains. In hot weather I use it opened up as a quilt. Down to the forty degree range I zip it up. And in the thirty's I wear a puffy jacket in the bag. I am 5'10'' and 150 lbs, this bag fits me very well. When this bag wears out, I will buy another Phantom Spark. I do not think I could find a better bag anywhere.

Rated 5 out of 5 by from Great size/ weight for backpacking Love this bag! Packs really small and ultra light. Perfect for my backpacking trip through South America and perfect both warmer and cooler climates. (This review was collected as part of a promotion.)

Rated 5 out of 5 by from I'd buy it again Absolutely loved it. As advertised, it's a snug fit so no cold pockets in the bag. First night out, my bear-can froze shut but I stayed cozy warm. The next day it poured on me and my bag was wet in the evening, but with some long-johns on, the bag kept me warm enough to get some sleep. When I woke up a couple hours later, my bag was warm and dry.

Rated 5 out of 5 by from Nice Bag I took this bag cowboy camping in New Orleans for 3 nights during Mardi Gras. The first night was in the Mid-60's and it was too warm. The next night was Mid-50's and still a little warm. The last night was Upper 40's and really comfortable. The only complaint I have, is that I wish the zipper went all the way around the bottom of your feet. That way you can unzip, and let your feet hang out.

Rated 5 out of 5 by from Fantastic Sleeping Bag Note: I specifically own the Phantom 32, but all of the features of the 32 seem to carry over directly to the Spark 28, so I hope this review can still be found useful by potential buyers. I've owned my bag for close to three years now, using it as my go-to sleeping bag for backpacking, canyoneering, sea kayaking, and whitewater pursuits. Down bags are generally terrible for water-related activities - I usually pack with me a Hyper Lamina Spark for paddling trips, but on a whim, I decided to give my Phantom bag a go. So far, it has worked very well. I generally sleep out cowboy style, as I live in the Southwest and rain is rarely an issue. Even when the temperatures drop or I'm close enough to a water source leading to condensation on the bag, I haven't had an issue with moisture negatively impacting my sleep quality. Moisture will build up inside the shell, but after an hour of airing out the bag, it dries out quickly and still retains its loft. While in the Sawtooth Mountains of Idaho, I realized in the morning that a Nalgene bottle had spilled and soaked the footbox of my bag, but I couldn't feel the moisture while inside the bag at all. An hour in direct sunlight dried out the bag almost completely. The bag compresses down almost to the size of a Nalgene bottle - my Thermarest pad is bigger when packed down. When space is a premium, this bag is incredible. I've used the bag at the Grand Canyon in temperatures down in the mid 20s without issue, even when sleeping out without a bivy or tent. I'm a warmer sleeper in general, which does contribute, of course, but the snug cut of the bag eliminates cold spots and with a simple baselayer of clothing on, I sleep nice and toasty. Again, the cut of the bag is snug. I'm broad in the shoulders, so overall I tightly fit inside the bag when laying directly on my back, but at 5'8", I still have plenty of room with the regular length to squeeze down into the bag and shift around. If you're a side sleeper, I would advise against the performance mummy cut style bags. When I first used the bag, I was concerned the 10D shell would be too delicate to handle anything but the most sensitive of handling, but it's a surprisingly tough fabric with abrasions and general use. It's even handled an energetic 90 lb black lab running all over it without a single scratch. The body zipper can get snagged, but it's been a rare occurrence overall and it's an easy fix. I've owned a variety of bags from various brands over the past 20 years and found that they all have a snag issue to some degree, so I don't hold this issue against the product. My only real gripe with the bag concerns the zippered collar pocket. I would like it big enough to hold a cell phone - as it is, it really isn't big enough to hold anything larger than a watch. I love my Phantom. I use it exclusively and would highly recommend it to anyone in the market for a lightweight, packable, and warm down bag.

Rated 5 out of 5 by from Awesome bag Sick bag, compresses down to the size of a Nalgene bottle. High quality, kept me warm in 30 degree weather at 9000'. Wouldn't take it much lower than that. Woke up dry, no condensation inside, plenty of room to store things you wouldn't want left outside the bag. If you're thinking about getting one, do it. You won't regret it.

Rated 4 out of 5 by from Great Summer Bag Used this bag in the summer months backpacking in Tahoe and the North Coast in California. Extremely lightweight and compressible, more so than I was expecting. This is the greatest feature. If not sleeping on a pad, the ground can get a little colder than I would like, but a pad will help with that. I will so do not expect to overheat in this. Though it's rated to 28 degrees, anything under 40 is really pushing the limit. I tend to sleep with minimal clothing which probably does not help either. This, in no way, diminishes how nice this bag is. For this reason I deduct half a star. The other half of star comes of from the zipper, it feels a little fragile, though it has not caught or snagged so it may just be in my head. The nylon is comfortable and soft and the hood is easily adjustable. And just as my girlfriends MH bag, there are two nice little pockets in the hood, one zippered and one velcroed, which are in the perfect location to not impede sleep, but still in a convenient enough spot to grab without having to get out of the bag.

Rated 5 out of 5 by from Warm and Light sleeping bag with one con. Just used this sleeping bag for a 30 day bicycle camping trip in Shikoku, Japan in conjuction with the mountain Hardwear Ghost UL2 tent. Most importantly this sleeping bag is the lightest and packs the smallest for any sleeping bag I have ever owned. The coldest is got during my trip was about 30 degrees farenheit whilst this sleeping bag is rated for 28 degrees. It held up very well. Once again the sleeping bag is very light and packs down very small. My only complaint was that the bag was tight in the shoulders....after trying it out at my local retailer in Japan I was not sure if I was going to buy it but ultimately did. I think that the narrowness may have kept it warmer on those cold nights and the tightness in the shoulders did not bother me as much as I was originally worried about. I highly reccomend this bag to anyone trying to lighten and minimize their load but will not be camping in anything colder than freezing.
