We have a downloadable packing list over by the Kinus applications. The packing list has been honed to perfection by years of experience. You do not need expensive outdoor stuff. Most of us do quite well with Target for almost all of our camping gear. They have everything you’ll need and at reasonable prices. I may not shop at Target if I were going to scale K2, but we’re talking about a weekend camping trip.
We do highly recommend that you buy true outdoor gear, and not the sleeping bags you might use for sleep overs. This also applies to tents too. The backyard play tents with cartoon pictures are just too lightweight for sleeping in the outdoors.
Oh, a helpful hint about tents: When a tent says it can sleep “X” number of people, it is talking about people being packed like sardines. We recommend that you buy a tent that advertises itself as twice the size that you need. For example, if you are two people, buy a four man tent. If you are three people, buy a six man tent. Also, if your kids are old enough to sleep on their own, you might want to consider getting two separate tents: One for the kids and one for the adults. Remember that you’ll be storing your gear in your tent too.
