Thread: Age old sleeping bag question

Hi all new to this site and this is my first post.

Just looking at getting a sleeping bag for myself. At the moment using my mrs kathmandu seeker which is comfy and warm but need to get my own.
Looking at the black stag 750, marmot sawtooth and macpac latitude in down but have seen the treksmart 3 which packs down pretty small for a synthetic and its pretty well priced. The marmot trestles 15 looks pretty good too. I am wanting a small bag comfort rated between -5 and -10 what are your thoughts has any one used either of the synthetics? Mont bell bags look pretty amazing...can a bag so light really be so warm? I wonder how much punishment they can take. I am a bit skeptical of manufacturers claims...if it sounds too good to be true.....

Cheers
