How long should a down jacket last?

My Mont-Bell UL Down Jacket from 2008 is still going strong, and it’s been used and abused.

I would expect as long as it’s been stored correctly (no UV, humidity controlled, and somewhat climate controlled – ie I wouldn’t think fabrics would like 130* attics) they should last a long, long time.

I would guess at least 10 years minimum for UL fabrics.
I’d argue that “Rock solid ” guarantee more briskly and ask for a replacement and see what happens

My feathered friends Icefall parka with a dry loft shell (I know, dry loft probably wasn’t the best shell fabric choice) is mint after probably 15 years of relatively light use in situations  similar to yours ( but a lot more days and hours of use than yours).

I even have an almost 50 year old Sierra designs “200 Perfect” heavy winter down bag that is fine, but the fabrics back then were quite robust. Was a Christmas gift from my parents and is rarely used these days

Thanks. We have replied disputing their conclusions. I suspect that if we had been able to return the jacket to our local store it wouldn’t have been a problem but with COVID restrictions in place, emailing photos to a bod at head office was more likely to receive a negative response. We have other jackets from Rab that are 25 years old and still going strong.

I have 2 Montbell  down jackets, 10 and 12 years old. They look like new still. They have had a lot of use in that time, not just for BPing. I wouldn’t accept MECs excuses.

I have a Gerry down jacket I bought in Junior High, 1972. A little less loft than new. 70d ripstop.

Like James R I have a FF Icefall parka (discontinued of course) which I first used on a winter trip in January 2010 so it’s 11 years old—after heavy use.  It’s shell is eVent.  Has around 15.3oz of quality down fill.  Still going strong and will accompany me on my next winter trip.

The lowest back baffles are woefully lacking in ample goose down but I have an old Exped downmat I could continue to cut apart and fill up my Icefall.  Most down garments are usually underfilled—too much fabric and too little down.  Btw, the snap-on hood is outstanding and can be worn alone when sleeping.
