<p>im thinking to buy a sleeping bag as my comforter...
ill buy a fleece blanket too..
will it be good? i think it will be more efficient.
will dorm room be so cold? like 50s/60s?</p>
<p>Most, if not all dorms, have heat. It's more likely that it will be too warm (as thermostats are often set too high or the building just becomes stuffy) than too cold. Some dorms also have individual radiators or thermostats in each room, so you can control how warm/cold you want it to be. You usually can't determine when they turn the heat on, though, so if there's a cold snap, it's possible that the heat won't be on. And it's always good to err on the colder side and just bundle up. Turn down the thermostat and reduce your carbon footprint. And as long as your sleeping bag isn't that weird shiny, slippery material, you should be fine. Some sleeping bags are basically comforters with zippers anyway.</p>
<p>I say definately. </p>

<li>Cold nights: good to sleep in!</li>
<li>If you get one with a nylon cover, it's cool to sleep with on hot nights too</li>
<li>Even if you don't sleep in it, because of the thickness of the padding, they'll make your bed a bit more comfy depending upon just how bad it is. </li>
<li>Camping! Always good!</li>
<li>If you like studying outside but don't want to lay in the itchy grass or ruin your favorite blanket, take the sleeping bag and unzip it!</li>

<p>--just make sure you don't get an igloo-style/mummy-style sleeping bag (the form-fitting ones). Get the ol' fashioned rectangle kind.</p>
