I'm planning on starting a thru hike starting May 15 (northbound). I currently have a 40 degree EE quilt. Is that good? I assumed it would be but just came across some info that suggested its not warm enough?

If not warm enough what should I do to remedy situation. I'm thinking either get a liner or bring a puffy jacket I could wear while sleeping. But a puffy jacket seems like overkill for that time of year.

Thanks.
