First Impressions and Color Discrepancy
I was really excited to receive the REI Magma 15 sleeping bag. The color, however, is a bit different than advertised. Instead of a deep black, it's more of a silver-gray. This wasn't a deal-breaker for me, but it's something potential buyers should keep in mind.
The bag itself feels incredibly lightweight. This is a significant upgrade from my previous Magma 30, which felt somewhat sparse with down and provided insufficient warmth.
Warmth Rating and Upgrade from Magma 30
My previous Magma 30, while advertised for 39 degrees Fahrenheit, felt cold. After contacting REI, they explained the technical rating but I found it wasn't comfortable for me in colder temperatures.
The Magma 15, rated for 26.5 degrees Fahrenheit comfort level, provides significantly better warmth. I'm very happy with this upgrade. The weight difference is noticeable; it's less than 2 pounds!
Zipper Design and Draft Collar
I appreciate the zipper design; it's particularly useful for hammock camping. The ability to zip up the bottom section adds extra warmth when needed.
REI's draft collar is excellent; it effectively prevents drafts and keeps me warm throughout the night. Although not clearly visible, the fluffiness of the collar is a key factor.
Temperature Range and Versatility
The Magma 15 isn't designed for extreme cold (15 Fahrenheit). However, it performs well in temperatures down to near freezing. With layering, you can easily extend its use.
Its lightweight nature makes it perfect for three-season camping. You can use it well into the fall and even pack it during summer trips for cooler nights.
Comparison with Magma 30 and REI's Warranty
Compared to the Magma 30, the Magma 15 is far superior in terms of warmth and comfort. The Magma 30 seemed under-filled with down and resulted in cold legs at night.
REI's excellent warranty made the exchange process easy. I exchanged my Magma 30 within a year without any issues, highlighting their exceptional customer service.
Features, Fit, and Overall Impression
I really appreciate the innovative zipper design, which seems to be a common feature in newer sleeping bags. The bag's roomy foot box is a bonus.
The Magma 15 fits my 44-inch chest and 5'10", 210-pound frame comfortably. It’s slightly larger than many other bags, with a 63-inch circumference. The color is also more appealing to me.
Conclusion: Is the REI Magma 15 Worth It?
The REI Magma 15 is an excellent three-season sleeping bag. Its lightweight design, effective warmth, and comfortable fit make it ideal for various camping scenarios.
While not suitable for sub-zero temperatures, its versatility and superior warmth compared to its predecessor justify the price. The excellent warranty further adds to its value. I highly recommend it.
