Cold sleeper solution
I recommend this product highly. I have the Woman's Marmot Trestles 30 bag. I knew the temperatures would drop into the 20s, and since I'm a cold sleeper, I decided to use it inside my bag. Initially, I felt cold, but by morning, I was comfortably warm and reluctant to leave my bag. It made a significant difference in the freezing conditions.

Significant warmth boost
This thing is a beast and a must for me when backpacking in cooler weather. Super lightweight, it adds significant warmth when used as a sleeping bag liner or cover. I paired it with my 30-degree sleeping bag and remained comfortable at that temperature. It's a no-brainer considering its weight versus value when it’s likely to get cold.

Reliable for cold weather
Worth every penny. I tested the bag last weekend at 34°F with a wind chill of 24°F, and I never felt cold nor did I have a wet bag in the morning. I will be getting more of these 8 oz bags.

Warmth retention
Worth the weight and money. It's a game changer, especially for UL hikers. With a quarter zip and a drawstring hood, it keeps warm air contained. The material is durable, akin to Tyvek, and softens after a few uses. I find it essential in my backpack for keeping warm and would recommend it to anyone. I've tested it in cold weather and found that it retains body heat and keeps me toastier than without it. Overall, it should be a staple in every outdoor kit.

Compact warmth enhancer
This is small, light, and adds warmth to my sleep system. I always pack it since it's so compact. When I get a chill at night, I add it and warm right up. While it may feel constricting as any "mummy" bag does, I recommend it to anyone concerned about being cold outside.
