Does anyone know the fill weight of a Marmot Baffin Jacket. I have checked their website and drawn a blank.

I currently am using a Patagonia Nanopuff pullover with 60g/m2 and want something a bit warmer.

I am wondering does the Marmot Baffin use 100g primaloft sport or 60g.

Anyone own both and can compare?

The Baffin appears to be using something other than Primaloft according to Marmot's site; Thermal R Eco. This is the only description of the material I could find:

Thermal R is Marmot's proprietary family of polyester insulations specifically engineered to meet various needs from sleeping bags, to garments to gloves. Mid loft, excellent warmth to weight, resilient loft, and durable.

I find my Nano pullover good down to freezing while stationary although I need gloves, hat and Capilene lightweight top.

at primaloft.com they describe a product called PrimaLoft ECO

made of post consumer recycled materials - soda bottles

they don't specify performance numbers

maybe that's what Marmot Thermal R ECO is

That would explain it. The Eco part. It says on their website

When you need a lot of warmth but not a lot of weight, this jacket features Marmot’s highly effective and durable Primaloft® insulation sewn into ultra light 15 Denier fabric to create an extremely warm and comfortable mid or outer layer for winter adventures. The Baffin Jacket also boasts hassle-free elastic cuffs, a Napoleon zippered chest pocket, and reflective logos.

Must be that primaloft eco soda bottle stuff.

I am hiking and climbing in Bolivia at the moment. I am currently using a nanopuff and a PHD yukon pullover. Its a superwarm and flexible combo however I would like to use only one jacket as I have been "wearing" my sleeping bag at night in the tent.

The down jacket is too warm when moving and the pullover a little chilly when the temps drop below zero.

I am looking for a 100gsm jacket that would hopefully do both and save on total weight.

I wish manufacturers would state fill weights.
