I have a black US Marine Corps modular sleeping bag for Intermediate cold that is perfect for someone not taller than 5'6" - small stature women, kids, etc. It is rated for -10F to 30F.
This bag was used in action and washed extensively which resulted in shrinking. I have slept in it at 30F comfortably but it's just too short for my 5'8" frame and I prefer looser sleeping.
Aside from shrinking and ID tag wear, this bag is in excellent condition - no snags, rips, tears or abrasions. Manufacture stamp photos are included along with measurements of this specific bag in the photos.
