- great sleeping bag down to freezing temperatures.
- depends what you wear inside the sleeping bag, but I feel comfortable without wearing much down to 0°C. I think there is room for much deeper temperatures (probably -10°C) with cloth-on.
- Very satisfied
- Well designed for comfort, warm, very light and compact when packed - what more could you ask for.
Questions & Answers
I recommend trying one of these bags in your local shop. If someone nearby stocks Western Mountaineering, then you should take the time to climb into both sizes and see which you prefer.
Most 6' folks opt for the Long. Thanks Jordan!
Thank you for your question.
Generally we would recommend sizing up if you are right at the maximum user height for a size (5'6" user in a 5'6" bag), however if you are looking to reduce pack weight as much as possible, or want to maximize the bag's thermal efficiency, going with a bag sized at a maximum of your height might make sense.
I hope this helps! Please let me know if you have any further questions or concerns.
