This bag is a really good option for anyone who isn’t a down fan. It has a cozy, tapered fit and is easy to customise for warmth (e.g. pop your feet out the bottom, use as a quilt, tighten around the hood). While it does end up being a bit bulkier and heavier than its down-filled counterparts, you gain durability and effectiveness even in damp conditions. If you’re looking for a solid down alternative that you’ll be tramping or camping in (that also doesn’t break the bank), this is absolutely a really good pick. For a warmer option in rougher conditions, this bag also comes in a -9 option.
