I had one some years ago and used it in May on Skye and must say i was chilly in it tho maybe ok in summer use.
Packs down small for a synthetic bag but it really is a thin bag maybe best used with other clothing.
Didnt keep it long enough for a proper review sorry...went for a summer down bag instead...
Hope that helps...
