Rei Lumen Sleeping Bag -

Built for the young backpacker, the 3-season REI Lumen kids' synthetic sleeping bag features amazing compressibility and warmth while balancing price and performance.



  • Synthetic Thermawave polyester insulation is durable and highly compressible; synthetic polyester fill retains some insulating properties even when wet
  • Equally distributed insulation accommodates the multi-position sleeper; mummy shape is thermally efficient, yet roomy enough to ensure sleeping comfort
  • Rated to keep your child warm down to about 25°F during adventures in spring, summer and fall


  • Full length zipper is backed by wide, antisnag binding tape

Weather and Wind:

  • Contoured hood, insulated full-face muffler, roomy footbox and full-length zipper draft tube with ground-level seams work together to keep heat in and cold out


  • External chest pocket keeps small essentials—headlamp, watch, glasses—right at hand and easy to find in the dark


  • Relaxed fit through the shoulders and hips gives you room to move for a better night's rest


  • Nylon stuff sack and cotton storage bag included
  • Shingle construction with overlapping layers distributes insulation evenly and keeps it from moving around so there are no cold spots
  • Ripstop nylon shell fabric has a nice hand feel, is lightweight, durable, water- and abrasion resistant; nylon taffeta lining is soft and tear-resistant

Lining and Layers:

  • Special pocket in hood can be stuffed with clothing layers to make a pillow that stays in place; no need for a pillow to take up valuable space in your backpack


  • Pad loops provide attachment points to keep your sleeping bag and pad together, so you needn't worry about rolling onto the cold ground (straps sold separately)


  • Differentiated drawcords (1 round, 1 flat) allow quick identification, even in the dark, so neck and hood adjustments are a cinch


  • Ideal for 10 - 14 year olds

Good for short adults, too!

I really like this sleeping bag. It's super hard to find a bag that actually fits me. I'm 5'4" 113, and even the womens regular bags are too long for me. This means dead space at the foot of the bag and also that I'm carrying around needless bulk. I think someone an inch, MAYBE two inches taller than me could use this (2 might be pushing it). This is really good quality for the price, especially compared to womens' bags, at least IMO. It packs pretty small, at least for the type of bag it is (regular 25+ womens bags didn't stuff down as small as this one), and the stuff sack provided is actually substantially larger than needed--I can fit my insulated exped sleeping pad (inflatable, 64 inches long) in it easily. I'm curious as to how small you could get it with a true compression sack. I haven't slept in 25 degree weather yet, but used it one night in the low to mid 30's (on top of a bouldering pad in a van with the windows open) and was very nice and warm. I generally sleep cold, too. I've also used it in Moab (cool desert nights) and was happy with it (on top of my sleeping pad). I like the fabric they put near the zipper--I haven't gotten it snagged yet. I wouldn't call this "roomy", at least given my size, but I almost prefer this as I feel like I'll stay warmer. Last but not least, I love the price for the quality, and obviously the guarantee (don't forsee any problems, though). This bag fits better, packs smaller, and meets all of my needs and yet is at least half the price of the adult bags I had been looking at. Hooray!

Great bag for the price

I find it amazing that someone else (who lives in Dallas) rated this great bag because it got cold (40 deg.) on a trip to Colorado. No way of knowing if that person had adequate gear, clothes, sleeping pad, etc, or even what the weather was. Were they cold-soaked? That's like buying a bike and saying you rode it in Colorado, but it didn't work like it should. Way too little information.

Bought this bag for my son who is 9 years old and he's already been backpacking with me at 6 years old in Mt. Lassen Nat'l Forest at 7,500 feet as well as Colorado, Utah, and last summer in the Chugach Nat'l Forest near Anchorage, Alaska. He did fine. I was sure to pack him appropriate gear and clothes, but he never complained.

Bottom line: great bag for the price. I have the adult version. Love it.

Overall a great bag.

I went to an REI store looking for back packs and bags. They were having a sell on this bag and since I'm only 5'4" I bought it. I have slept in it many times in a backpacking hammock. I have slept in a few times down below freezing in Yellowstone National Park (I did have it inside a bivy bag) and the only thing that got cold were my feet. I've never had that problem before. It's almost as if a draft comes through down there! Anyway, that's the only reason I didn't give it 5 stars. Other than that I LOVE this bag.

Bought this sleeping bag for an overnight camp with the cub scouts early November. It turned out to be a lot colder that night than anticipated - probably well below freezing (given the ice on the cars' windshields). My son was warm and comfortable all night! (I was not)

I had filled a water bottle with warm water and stuck it in his bag to heat it up before my son got in. The water was still warm the morning after...

2 important features for young boys: 1) a little pocket on the outside to store the flashlight. 2) It's blue.

Nice Bag

Used this bag for my son for the first time. Got this to replace an older bag so that it would fit into his small bag. He's 8. Our first night was much colder than we expected and was in the high 20s. I was cold in my 25 degree bag but he was pretty good in this one.

So it packs pretty small and kept him comfortable in 25-30 degree weather.

Works for my son

I bought this bag for my son two years ago for backpacking and boy scouts. It has served him well so far. He has stayed warm in mid 30 degree temps. Construction seems good. For a synthetic bag it packs down pretty small. A good bag for the price.

My son likes his sleeping bag - finally

My 13 year old son an I do a fair amount of backpacking. This year we have a 50 miler coming up and he needed a light bag with a cold weather rating that will help in the Sierras during fall.

Would purchase again-grandson loves it

Purchased for 10 year-old grandson. Planning trip to barrier island this winter for weekend school trip. Great fit for his frame. Looking forward to extensive use on family ventures!!

Comments about REI Lumen +25 Sleep

I am a woman 5'2" and I weight about 110 lbs. I bought this bag because I thought I would get a great deal money wise as I am small and perfectly fit in the bag. I went camping to the South Rio Grande National Forrest in Colorado where the lower temperatures reached about 40deg F. I froze! If you are a person that gets cold easily I do not recommend buying this bag. Spend the money and invest on something with lower temperature ratings. I will hopefully exchange my bag for a +10 or +15 degF bag.
