Personally,I think an 11 pound shelter and stuff that goes with it,is impractical for packing in that far.Keep in mind,we can't pack as light as backpackers because we have hunting gear and cloths.I use to hunt like that and a pack for 10 days,would weigh 55 lbs.That didn't include bow.The shelter was a tarp tent,groundcloth etc that weighed about 3-4 lbs and all the food was freeze dried.
My current setup is a small backpacking tent with fly that weighs about 3 1/2 #.I will hold me,my bow and pack and I can cook from it with a backpacking stove if I have to.It can be sealed up to shut out the wind but is still ventilated.Packed,it is very compact.
I personally would keep a shelter under 4 lbs.I also use a bag that is about 3 lbs and is good to 0,a little warm for a hunt that time of year.
I would make a list and weigh every item you have,that you might carry and add it up.Pack the stuff and see if it all fits.
If you get a small bear,it will take one trip for your gear and one for the head and meat.Figure about 1/2 the bears live weight for the hide and meat weight.350# is probably the biggest you might encounter in Spring here and there won't be many of those in a given area.
Don't forget,you may be dealing with some altitude that you aren't used to and also realize that there may be some days so windy that you can't keep a fire going.
In 22 years here,Spring bear hunting,I haven't needed expensive clothes.If you want to spend a little extra money,put it in boots and a light weight camp.
