Reddit mentions of Coleman Green Valley Cool Weather Adult Sleeping Bag

Things I've bought on Amazon and highly recommend:

• Toilet seat covers, because port-a-potty:

For 3 season car camping? No way.

• Sleeping Bag - $30.25 - that'll get you down to 30-50 degrees. I saw a 5º rated bag on Amazon for under $40. Or for you, here's an extra long 30º bag for $33.99
  
• 3 person dome tent - $49.99 - plenty of space for a couple and their gear.
  
  That's literally all the specialized gear you need for camping, and it's Coleman stuff which isn't high end but it lasts just fine. Everything else you can find around the house—a knife (any will do), some matches, sunscreen, and bug repellant. OK, if you never go outside you might need to buy those last two. You don't need to buy a first aid kit. You have basic medical supplies around the house, right? Toss a few of each item in a ziplock.
  
  I've just outfitted two people for $110 without even shopping around. If you want extra comfort, add an air mattress for $40 tops (unless you can borrow one or already have one for guests). You're still at less than the cost of two nights in most hotels.
  
  Granted, if you want to do backpacking you're going to want to invest in some lighter weight items. But for car camping? No need, the cheap stuff does fine.

A sleeping bag.

I've been losing weight, and my boyfriend wants to go hiking/camping with me. However, I don't own a sleeping bag, so I can't go with him. I desperately want to get the funds together to get one, but I'm just not there yet! I would like to show off to the world how much stronger i am becoming, but this stupid sleeping bag is holding me back. :(

Just get an inexpensive summer weight sleeping bag rectangular not mummy, and unzip it all the way so it makes a blanket. Be sure to get flannel lined, or it will keep slipping off your bed.

An excellent trick for car camping too by the way. Cover a not-warm-enough mummy bag with an unzipped rectangular bag as a quilt.

Do you need it for backpacking? Or just car camping?

If it's car camping then just get a flannel bag which would run you less than $45.

If it's backpacking then the cost will be higher due to materials.

• The Marmot Mavericks 40 is a good choice, but at the top of your degree range. You can always wear warm layers to bring the comfort level down.
  
• The Trestle is a nice bag for the price, but is BIG. So like you've heard it bulky and heavy
  
• The Cosmic Down provides a bag with a hood and down. Which is why it's more expensive than the Mavericks.
