That’s an awesome jacket — the REI Magma line is one of our all-time favorites, and we’re excited you picked it up! The good news is that the puffiness will come back, but down garments can’t be washed like regular clothes. You’ll need to use a down-specific detergent, which cleans without stripping the natural oils keeping the down lofty and insulating. It’s a bit of a process, but not a hard one — just make sure to follow the right drying steps to fully restore the loft. Check out our step-by-step guide on how to wash a down jacket for the full rundown. Following these steps during a re-washing process will help your Magma regain its fluff and keep performing great for years to come. Thanks!
