Don't be left out in the cold without your Slumberjack Sleeping Bag Pillow included / Roll-up Hood
Customer Review: Nice
My son loved the frogs and it seemed like a perfect fit. I could see how the material may easily rip in the wash in the future and don't buy it for the pillow! It easily rolls up and velcros for easy storage and carrying. Overall, we like this product.
Customer Review: Nice Sleeping Bag
Very nice sleeping bag. Seems to be made well. The pillow is little but it's suppose to fit little heads. Someone had said theirs had come in a clear plastic bag, but mine came in a box...it did have the picture on it but it was a gift so it was wrapped up. My grandson did like it.

Sleep Well: Finding the Right Sleeping Bag
Sleeping bag technology has come a long way from the days of cowboy bedrolls. These days, there are a number of high-tech materials and designs available to keep you warm during the coldest outings. Here's a short list of things to keep in mind when you're shopping for a bag:

Buy for Cold
It's a safe bet that on at least one of your adventures, the nighttime temperature will drop unexpectedly. That's why it's smart to buy a bag that's rated for the lowest possible temperature you expect to face on your camping and backpacking trips. For summer trips, a bag rated at +35 degrees or higher will likely do the trick. If you like to camp in higher elevations in the summer, or if spring and fall outings are in your future, consider bags rated from +10 to +35. Winter adventurers should look for bags in the -10 to +10 range, while those on serious winter alpine climbs and expeditions will want a bag rated lower than -10.

Keep in mind that sleeping bag manufacturers' temperature ratings only estimate the minimum temperature at which the bag will provide warmth. Take these numbers with a grain of salt, as different folks generate different amounts of heat when they sleep. If you're the type who likes to pile on the covers even on warmer nights, go for a bag that's rated ten degrees colder. The opposite is true for "warm" sleepers--a 35-degree bag will probably work for you on a 25-degree night.

Goose or No Goose?
The most important component of any sleeping bag is its insulating material. Modern sleeping bags offer two choices: goose down or synthetic. While both materials have advantages and disadvantages, down bags are considered superior because of their phenomenal warmth-to-weight and warmth-to-bulk ratios. While providing great insulation, down is extremely compressible and light. There's a reason why geese can fly and stay warm through the winter! Down also boasts great long-term durability and will typically retain its insulating properties after years of use.

All of that said, there are many high-quality synthetic bags on the market and synthetic materials are getting better all the time. While a synthetic bag will weigh somewhat more than a down bag at an equivalent temperature rating, synthetic bags perform better when wet. (Yes, the Achilles heel of down is that it loses all insulating properties when wet.) If your trips take you to wet climates, you may want to consider a synthetic bag for this reason alone. Keep in mind, too, that many people are allergic to down--synthetic bags are non-allergenic. Finally, down is considerably more expensive than synthetic, which might tip the balance for adventurers on a budget.

Bags for All Shapes
Sleeping bags come in two basic shapes that reflect their intended use. Mummy-shaped bags offer the best warmth because they conform to the body's contours. This minimizes the amount of body heat the body must put out to maintain a constant temperature. Many mummy bags are offered in women-specific shapes and sizes, as well. Rectangular bags, while they do offer more room to toss and turn, are less thermally efficient because they contain more open air space. Also, they are typically heavier than mummy bags, and are generally not offered with down insulation, making them best suited for car camping or short backpacking trips.

Pad Yourself
No matter what kind of bag you choose, a sleeping pad is a required accessory. Not only do they provide much-needed comfort when sleeping on the ground, pads also offer crucial warmth for your backside, as the weight of your body compresses--and renders virtually useless--the sleeping bag insulation that lies beneath you.

Customer Review: Slumberjack Telluride
This was the first new and improved, highly compressible sleeping bags that I've purchased. Gone are the days for me to lug around a sleeping bag the size of a large carry-on. Although I now own and use the Big Agnes Encampment, I didn't have any issues with the Slumberjack Telluride when I did use it. It packs small with the included compression sack and is very roomy and warm at tempuratures above 35 as long as you use a good pad or cot below you and you are not a cold sleeper. The material is smooth and comfy and for me the zippers worked. Although I do admit that I rarely use them. I simply work my way into the bag as though putting on a pair of socks. Anyway, I do recommend this bag for those that don't camp that often, are on a budget, have the patience to not force the zippers or just want to have a good sleeping bag around without taking out a second mortgage.
Customer Review: You get what you pay for
I bought this bag for a 7 day bivouac hunt in the North Dakota Badlands. The average nightly temps were 40-50 F. The bag was warm during these windy and chilly nights. The bag compresses down reasonably small and is relatively light weight. On my second night of the hunt, I was zipping up the bag and the zipper broke right off of the bag. It didn't just come off, it literally broke. There was no way to fix this in the back country. I had my hunting buddy wrap some duct tape around me at night and then unwrap me like a giant tamalie every morning. He spent big $$$ for his bag and of course, had zero problems with it. Oh well, for the price and free shipping, this isn't too bad of a deal, just remember to bring plenty of duct tape with you.

Don't be left out in the cold without your Slumberjack Sleeping Bag Fully contoured hood with flip-over option / Easy access drawcords / Half-length, insulated draft tube with anti-snag zipper protection / Easy-grab pull tabs
Customer Review: Decent Bag
This bag is very comfortable and packs relatively small, but on the downside it is a bit heavy and the merino wool liner is sometimes itchy (particularly after a hike when dried sweat is on you). It is spacious on the inside for those who like to some wiggle room. But this also affects the overall warmth. I tried it out when the temperature got a to be about 25 degrees and the bag was pretty cold, but after putting on some shirts, tights, socks, sock cap.... it was toasty. So the rating is a bit off. But overall it is a well rounded bag for three season backpacking and will do the job.
Customer Review: Termperature rating is wrong
This sleeping bag looks great. It is light and comfortable as long as it does not get below 40F. I went camping with the Slumberjack Kepler 20F Regular Right Sleeping Bag and the temperature went a little below the freezing point on a couple of occasions. I had terrible nights both time. I took off my cloth, wore more cloth and there was nothing to do, I was cold. The temperature rating on the bag is wrong. The sleeping bag is at best a 40F. I ended returning the bag. Amazon's service was great.

Oversized for hunters and fisherman, the Slumberjack Big Timber rectangular sleeping bag features a 10-ounce cotton duck outer shell and heavy-duty zipper. The roomy proportions and warm, 100 percent cotton flannel liner guarantees a restful sleep, and it's temperature rated to -20 degrees Fahrenheit. It offers a double layer quilt-through construction and Slumberloft HQ fill, which provides great warmth and loft at a great price. Other features include an insulated draft tube with anti-snag zipper protection, an adjustable storm collar, easy-grab pull tabs, and compression straps at the bottom of the bag. This long bag has a maximum user height of 6 feet, 5 inches.

Customer Review: great buy for big guy
This product is well worth it. I go camping a lot. There's plenty of room which I love. I'm 6'2" 265lbs so if your big get this bag...I slept great and was nice and warm. Bigger than I expected.
Customer Review: Winter Sleeping Bag is WARM & QUIET -Love it!
This sleeping bag is really great. It is far warmer than my other nylon bags, and comparable to a 6 inch thick down comforter. And I mean that in a good way. The cotton duck outer (like soft canvas) and comfy flannel inner is just awesome - and QUIET. I just love the quietness. All my older bags have been nylon which make a lot of rustling noises which bother me everytime I move (and anyone else trying to sleep nearby). This SlumberJack Big Timber long sleeping bag is so cushy soft you almost don't need an air mattress. But you'll sleep better if you do have one. I can highly recommend the ThermaRest Base Camp air mattress. It's really great, and last for dozens of years! Therm-a-Rest Base Camp (Large) The one thing to be aware of is that no air mattress does well if you leave it all blown up in a hot trailer. It will pOp! or at least get a slow leak. If I hadn't done that, I'd still be using the same ThermaRest I got in the 1980's and slept on sharp rocks & broken glass without a puncture nor leak. Tough! So deflate it some before you leave it for the day (or season) and you'll never have a problem. This sleeping bag has a BIG square foot end, so there is tons of unrestricted room for feet. Totally opposite of mummy bags. Zipper is good quality metal. I sometimes feel a slight draft near the zipper, but this bag is so warm that is ok - just slightly refreshing. This bag is wider than most, which is ok - I have plenty of room. But it might be a squeeze in a small tent. This is NOT a backpacking bag. It's too bulky & heavy to lug around all day. But it's perfect for car camping! It's possible to use this bag in the summer, but you will be opening it just to cool off about half the time. Get yourself another sleeping bag for summer. This is the most comfortable winter sleeping bag I have ever had, and I'm happy to recommend it now. EDIT: I actually have the 0 degree bag. I still love it.
