I have read a ton of threads on this forum…but few are recent or provide the insight I’m looking for. I’ve also tried to read a ton of online reviews, but I’m still confused.
I have a Patagonia Nano Puff Pullover which has 60g synthetic fill. It’s not as warm as I would like, however the weight and cost are good.
I can put it over the R1, and under the Houdini…still I think it’s not quite as warm as I would like sitting around camp. I don’t use this during exertion, so breathability is less of a concern unless it traps moisture and then provides less warmth. Moisture resistant down is preferred.
I’m trying to evaluate down jacket alternatives based on:
- Meets minimum warmth threshold (stationary, 15 deg – can be paired with down hood, R1, Houdini as needed)
- Weight (6-12 oz)
- Cost
- Durability (less of a concern as I don’t intend to use it during activity that poses a threat)
Nano Puff (9.4 oz total, 60g insulation, 22d)
I have been considering:
Montbell Ex Light Jacket (5.6 oz total, 1.8oz 900fp, 7d)
Patagonia UL Jacket (9.5 oz total, ?oz 800fp, 15d)
Mountain Hardware Ghost Whisperer Jacket (7 oz total, 2.6 oz 800fp, 10d)
Feathered Friends Hyperion (11 oz total, 4.7 oz 850fp, 10d)
Some of these can be found on sale, others are prohibitively expensive. I’m curious if there are other options, possibly not the main brands and less well known…or better value for the money in terms of warmth and durability. I don’t need or want features. I don’t care if it has pockets. I just want a cinch cord at the waist if at all possible and snug fitting wrists.
Which of these are noticeably warmer than the nano puff for roughly similar weight (up to ~12 oz)?
I’ve tried to read reviews and charts/data on insulation values.
