What is the best way to store a down suit?

I just got a new TNF Himalayan suit and it only came in a plastic bag.
I'm looking for the best way to store and transport it (preferable a available product).
I was first thinking of a duffel bag but they are not breatable.

I would store it openly, hanging in the locker like a coat.
For storing it during traveling, I would use a big bag like you usually get for sleeping bags, there it can breath. When a high level of compression is needed for a short time like four or fife days, use a waterproof duffle bag or something of that like! Don't worry about the breathing for a short period, waterproofs comes first. But for long time sorrage use the locker as mentioned.

Ah and if you need suitable boots for your suit, check out my post,there Iam selling a scarpa phantom 8000 in 45 european size. cheers

Thanks for the suggestions. Closet storage will not be available for some time. I have been looking for stuff sacks and other sleeping bag packs, but i have hard time finding somthing breathable. Suggestions to spesific producs would be great if anyone has any.

I'd love a pair of Scarpas for my cold feet but I'll have to wait to buy more, and they are one size to small for me.

use a cotton pillow case.

Or a cotton sleeping bag storage sack. Like this one from REI.

Yeah, I think the cotton bag is exactly what you are looking for!

Thanks Dave.

This looks like a good solution and they ship overseas.

Cotton pillow case and do NOT hang. My down lies flat under the bed

Dont use a pillow case for a suit it wont be big enough and will slightly compress the down, i would recommend a cotton or poly cotton sleeping bag liner and i would also store it under your bed, with nothing on top of it.
