Rainier Climbing List

What route?
What are your thoughts on a bivy bag?

This list would be for the Disappointment Cleaver or the Emmons Glacier in the summer. Not sure what you mean by a bivy bag but I am assuming you mean a half bag? I already have a bivy sack on the list. I would personally rather have a full length sleeping bag just for warmth's sake, and I am not sure if the Montbell Alpine light would do well enough as the top portion of the half bag. If I were to go that route I would most likely have to bring my TNF Nuptse Jacket for that layer.

Well, you listed a water resistant bivy bag but also a tent (that you will likely split). Why not just go with waterproof a bivy bag?

Either way, beats that nasty shelter.

Another idea might be getting rid of the softshell for a lighter fleece or a winshirt. More versatile and probably lighter.

Is the soft shell coat good for high winds and rain? Does it
have a hood? If not I would switch it for a hard shell.

this may sound crazy but I'm bringing my Montbell UL Down Parka, a light fleece, and a GoLite Virga Jacket. I'm going at the end of June. About a month ago, I went to camp muir- complete whiteout, snow, high winds and 13F at the top. Virga kept me nice and dry, and Montbell is a miracle jacket… so am I going too light? seems like you are concerned about being not too warm, but you have a 12oz fleece and a warmer down jacket. i will be checking forecast though and planning accordingly.
