what sort of sleeping bag are you after? synthetic, or down? budget is a key factor. Also if you are a particular build it can have an effect on what you should buy. I personally just bought the SnugpakSoftie Harrier 10, for a 3 season synthetic it packs small and light at CA 1600g but a down equivalent will weigh less, pack smaller but cost more. I find the one i bought is very comfy, almost feels like a down bag, its also very roomy and being 6ft4 (191cm) the extra size is great for me as i can properly bury myself in it. I also bought a snugpack travel light self inflating sleeping mat, its weighs in at 500g and packs down small but is only about 1" thick and not so good for rocky ground, but i bought it to use in a hammock.... when i was looking and checking things out on the forum i heard lots of good things about the Alpkit mats so i'd check them out. or you could go with the old faithful foam roll mat. There are quite a few threads and discussions on this site about the pros and cons of the different mats and types of bag so id advise taking the time to read these.
