If someone is honestly looking to spend some coin on their first quality sleeping bag, i so strongly suggest a versatile sleeping bag, get one you can walk around in at night with pockets like the exped wallcreeper or the feathered friends rock wren or winter wren.

marmot used to make the Alpine NEST series bags, which rocked. the exped currently is available as either down or synth. the large size expeds are HUGE so be careful if you are contemplating the large size sleeping bags from exped.
