Product Review! REI Co-Op Magma 15 Sleeping Bag unboxing

I got a new sleeping bag! I finally have the bag I plan to take to Yosemite and I wanted to show you not only the look of this bag (which is brand new on the scene) but my entire sleep system. It is VERY warm and has great compression. Enjoy!

Here is a peek at that Sea to Summit Compression sack before it is filled. I am loving these and have a few. Sea to Summit is also a brand I have heard a lot of excellent things about from other backpackers. The compression sacks have worked really well for us and I look forward to trying more of their products in the future.


When I first tried to get the bag in the compression sack, I have to tell you, I was not sure it would go in. hahaha It is such a fluffy sleeping bag! It feels huge! It makes my Coleman bag feel comparatively thin. Yet, it all went in because compression sacks are backpacker magic. Which is why I frequently say to REI, “Take all my money!” Backpacker magic. Camping magic. Harry Potter is real! Okay, so maybe I can’t use a wand here, but it is really helpful.


I put this Nalgene (the water bottle that will never die – ever – even if you wish you could get a new one haha) next to it to give you an idea of how large the compression sack is compared to that huge bag. Also, before you buy your compression sack, make sure you know the specs. Most bags will tell you how much space they need even when compressed. Otherwise, you will find yourself in a pickle, my friends.

Here are the steps to my sleep system. This Klymit Static V is EVERYTHING. I need to do a separate product review for just it because it is one of my favorite purchases EVER.


Can you tell that I am excited about this bag? So the REI Co-Op Magma 15 sleeping bag is very cozy and comfortable. It has a flap inside that you can pull up to your neck to keep you even warmer and has cinching straps that tighten the bag down around your face to keep even less of you exposed to the elements. As I mentioned in my video, it comes in long and regular so that you can get the right length for you. I am only 5′ 1-2″ (the doctors debate between 1 and 2 inches so I feel it is my duty to let you know that I am somewhere in there. I wouldn’t want you to feel deceived ha) so I do not fill up this bag. I will just stuff some extra stuff in the bottom to create extra warmth. With my daughter’s sleeping bag, we have also tied off the extra part of the bag with rope or a rubber band and that helps her, so there is another option for you. On my last trip, I stuffed the bottom with my fleece while I wore my puffy to sleep and it was perfect for that weather. I will keep experimenting though. I did not experience any leakage of air through the zipper which is a common issue with sleeping bags that are a more reasonable price. Do you have any other questions about the bag or my sleep system? I’m happy to elaborate!

Until then,

See You Outside!
