There are a lot of good brands out there some will cost more simply because of their name. Almost everything these days is made in a few factories in China, Korea, Vietnam and the Phillipines. Many factories make several brands side by side. So you may be able to choose a less expensive brand and still get quality.

If you are starting out then don't spend too much and find out that you will never use all that gear again. Most REI stores rent tents, sleeping bags and mattresses. That may be a good option.

REI brand tents are a good value, so are their sleeping bags.

Almost every brand mentioned is worth buying. Look for quality in the parts and workmanship. Look for sticky zippers on sleeping bags; avoid these. Make sure the tent has aluminium poles the fiberglass cost less but WILL break more quickly than tha AL which will bend first.

Down is considered superior for sleepin bags for comfort and warmth to weight ratio but if it gets wet it will be useless. Synthetics like Polarguard 3D and Delta are heavier and bulkier but will keep you somewhat warm if wet.
