Could someone review my gear list (clothing and sleeping only) for camping at Mt. Rainier?
I am spending a night at Camp Muir.

Tent: Big Agnes Fly Creek UL1 (1 person tent)
Base layer: light & medium top and bottom
Pants: NF Paramount hiking pants (convertible), hardshell
Top: light fleece and a hardshell
Shoes: Merrell Moab waterproof low cut
Gloves: NF runner's gloves and TNF Apex
Neck fleece gaiter
Fleece hat
Socks: heavy wool socks
Sleeping bag: North Face cat's meow 20F

I was told that it has snowed quite a bit, so I think I will need ankle gaiters..
And, I am not sure if I will need a soft shell as another insulator or bring a parka for the trip to Camp Muir?

Could anyone suggest what I need or not need?

Thanks.
