I have a like new Feathered Friends Peregrine -25F sleeping bag looking for a new home. I’m asking $750. It is the “Long” version of this bag: https://featheredfriends.com/products/peregrine-es-25-sleeping-bag?variant=43549007610055 Comes with a storage sack, cinch sack from FF, and I’ll add this compression sack (https://www.rei.com/product/246134/sea-to-summit-evac-lightweight-compression-dry-bag?sku=2461340004&store=38) which will help you get a little more space in your winter backpack. Good luck on your preparations for winter expeditions!
