Comments about The North Face Lynx 40F Synthetic Sleeping Bag - Regular Size:

I bought this bag over a lower temp bag to reduce my carry weight for a 78 mile trek at Philmont. I am using warm sleeping clothes since I can wear those outside the tent if needed, and a warmer bag I cannot wear.

My son & I tested these bags in windy wet conditions down to 35 F. He was toasty and I cool so I put on my fleece in the early morning hours. We were wearing socks, light weight long-johns and thin polyester shirt, no hat. I tend to sleep cold so I think the bag does as-good if not better than the rating. Note that this bag has the newer European temperature rating that many other bags still do not have.

The quality of design and construction is fantastic, and the bag is light. The stuff sack is made very durable so appears to approach the weight of the sleeping bag. For Philmont I will use an inexpensive light weight dry-sack instead to save weight.

Very impressed with the quality and performance, so well worth the money. I bought the less expensive left-zip style.
