Rating: 5 / 5
Purchased in 2005, weight is 6 oz.
As an experiment, I recently used them with my Montbell UL Down Inner Jacket instead of my sleeping bag for some overnights on the Tahoe Rim Trail. Nighttime lows were in the low-40s and I couldn't have been more comfortable.
I now plan on using them to boost the rating of my 15F bag for winter backpacking.
The fabric is delicate, but a pair of rain pants over them will protect them just fine.
On a side note, you won't win any fashion awards.
