Warm as advertised, but also comfy in warmer temps, good value, lots of thoughtful design features - Marmot Trestles 15 Sleeping Bag

Took this baby out for its first spin up at Granite Park Chalet in Glacier National Park, Montana, USA in early July. Socked in mountains with low-lying clouds and rain by day meant a cold night in an uninsulated bunkhouse, and this bag kept me super warm as advertised. It didn't get down to the rated 15 degrees F, just low 30s and upper 20s if I recall, but I was still snug as a bug. Lower down at St. Mary's Campground on the east side of the park and at a campground outside the park to the west where we stayed a couple of the other nights, nighttime temps were much warmer, but I was still comfortable in this bag, not overheating, which is exactly what I was looking for. I appreciate the design of this bag--it's very logically and thoughtfully designed as far as where the zippers are located and how the cinches operate when inside the bag--small creature comforts that make a difference. This same bag retails for like $110 to $120, so snagged this on a pretty good deal under $90. Highly recommend it and I love the colors (which is the navy blue with bright azure blue combo--it can be kind of confusing what color combo you will receive from the pictures and choices), and I hope to have this bag a long, long time!
