FS • CLOSED • Marmot Helium 15F Sleeping Bag 850+ Fill Power Goose Down Regular Size, 25 oz, 6′

weighs 30 oz not 25 oz

Price drop $195

approx how many nights used??
MFR says 34oz and 800 FP…?

on my scale 30 oz and this is an older version so I think it’s valid. I picked it up on ebay and never got an answer about how many nights use, however it doesn’t look like it was used at all and still has plenty of loft. this one also has the short zipper, not a full zipper.

ok cool…how many oz of fill? were u able to find that?

no don’t know how much fill, when I looked to see other things they were selling on ebay, it was being sold from some kind of a store, not camping gear. I had a sleeping bag like this one back in 2010. I’m 5′ 11″ and length wise I had plenty of room in the bag probably good for someone up to 6′ 2″.
Anyway I asked AI and got this answer:

Marmot introduced the iconic Helium 15-degree down sleeping bag around 2002–2003 as an ultralight, limited-production specialty item. The original regular-size version contained 19 ounces (approx. 538 grams) of ultra-premium 900-fill power goose down and featured a partial-length zipper to shave off extra weight.Over the years, Marmot updated the Helium line by transitioning to 800- and 850-fill power down, incorporating water-resistant Down Defender treatments, and eventually adding a longer/full-length secondary zipper for better ventilation. Modern regular-size iterations of the Marmot Helium 15° Sleeping Bag typically feature an insulation fill weight of about 19.75 to 20 ounces (around 550–560 grams) of 800- to 850-fill down

I decided to keep it until winter to compare with my other sleeping bag.
