Supplementing Mont bell thermawrap on 11/11/2010 13:15:03 MST Print View

With winter quickly approaching I was curious what most of you carry out in freezing temps (mid to upper twenties). I carry a thermawrap late fall and early spring but have been using a marmot guides down sweater in the winter months, which is way too HEAVY. I have started looking at the montbell permafrost light down. I just want to sit around camp warm without carrying more than one jacket.

I add warmth from underneath. I use a midweight Patagonia fleece sweater along with a BPL Cocoon Hoody (which is similar to the Thermawrap). Generally speaking, the Cocoon Hoody stays in the pack until I stop. The weather in the Northwest is often damp, with temperatures a few degrees either side of freezing. Since I tend to cross country ski when I travel in the winter, I'm generating plenty of moisture, so I like the fact that fleece breathes so well. I should mention that I also have a fleece hat. I put the Hoody on when I stop for a break, or ski downhill. I also have a thin fleece balaclava for when it is really cold.

Probably the lowest temps would be low twenties. I was thinking the permafrost light down would get me there but I also don't want overkill. Again using it once I get to camp just sitting around. I also read the other recent post mentioning the new frostline parka. The one big difference is the permafrost light down has the windstopper technology. I don't know how much of a difference that really makes. I have done some winter hiking, I just want to carry the right stuff to minimize weight and maximize warmth.

5-6 oz of 800 fill down on 11/11/2010 14:25:34 MST Print View

something with 5-6 oz of 800 fill down ...

alpine light down is the very lightest id consider taking into the mid/high 20s by itself ... i have a westcomb kokanee which is a tad warmer for those temps

tons of jackets in that 15-20 oz range with 5+ oz down

you wont save that much weight over yr marmot ... if that works for you ... maybe 5 oz

id just stick with the marmot personally if it works ...

Consider the Feathered Friends Hyperion, Western Mountaineering Flight, or Nunatak's Skaha Plus... all about 10 ounces and warm. Skaha Plus is baffled & hooded, comes in at $369. Hyperion & Flight are sewn-thru & non-hooded, but great jackets, at ~$225-250.

i wear a a patagonia micro puff pullover when stopped and in camp. my base layer would be a nike drifit or mammut dri-release long sleeve shirt. over that goes a cloudveil walk don't run power-stretch hoodie and over that goes a wild things windshirt or flume hard shell. the micro puff can be worn over or under the windshirt, but only under the hard shell. i also carry a supplemental polartech hat that i can wear under the hoodie. haven't been cold yet. when there's a chance the weather is going to be warm enough that it could rain or i am potentially going to throw the layer on when wet i stay way from down jackets. i know that a lot of them claim to address the water issue, but i have a healthy fear of being cold, wet and not being able to warm up.

I use all of my current 3 season gear in layers for the winter. Baselayer (8 oz) and windshirt (3.1 oz) for hiking, nano puff (9.7 oz-similar to thermawrap) on top when stopping briefly, and my old patagonia down hoodie (14 oz) on top of that when making camp or ice fishing (what can I say- I live in Michigan). Combined with fleece gloves, overmitts, and a balaclava, this setup has kept me comfortable down to -7 F with heavy wind. I could save more weight by ditching the nano puff and down hoodie and getting a heavier down jacket in place of them, but I like the versatility of the layering system and the fact that I get to use one set of gear year round.

Mont Bell Great in Patagonia on 06/09/2011 22:06:07 MDT Print View

The Ul Thermawrap was fantastic for my two month trip in Patagonia's summer (snow,rain, wind, wind, wind, and occasional sunshine). It is so versatile. For cold temps (high 30's), I wore a wilk undershirt, with a polyester/spandex overshirt, then the UL. For wind (upwards of 60-70 mph), just used my mountain Hardware rain jacket. Even by itself in a light rain, it does fine. Since returning, I wear it around the house with a tee shirt. Barely take it off. It's a winner!
