Snow Leopard

 The Snow Leopard is my sleeping bag of choice as the plusher synthetic insulation is far more plush than the very-thin down alternative. Plus, its rated to 12 degrees, meaning it’s comfy down to about 25. The trade-off is that it’s heavier and larger than its down counterparts, but I bought it as it was the biggest one I could stuff into a 20 liter Sea To Summit Compression Dry Sack. That makes it a great alternative if you want added warmth and comfort, but don’t plan on hiking and space isn’t at a premium.
