UL Thermawrap v. Micropuff pullover

I can't speak about the thermawrap, but the MicroPuff is very toasty.

I've worn it with only a short-sleeved tshirt underneath on a 3 mile hike in 15-degree (f) temperatures. The wind was blowing at a steady 15mph, and I was quite warm enough. Unless you're cold-blooded, I think it would be serious overkill for a low of 40 degrees.

It's got a DWR finish that has worked well with very light rain and light snow, weighs 13 ounces (extra large) and compresses down to about 5" x 9" in its own stuff sack.

It's also sized to layer over other things which would make it useful for much colder temps and I can still get a rainshell over the top of it.

If I could add one thing to the MicroPuff, it would be slash pockets at the waist for my hands…and maybe a more substantial zipper, even though it would probably mean an additional gram or two.

The micropuff would be overkill for me at 40 degrees.

Jon,
I own the Thermawrap, and with a wool2 base layer I am fine down to 40F. It blocks most of the wind, and just lets some persperation vapor escape.

There is a hooded version which will prevent the large heat loss from an uncovered head, and venting around the next collar; or just always carry a wool or fleece watch cap.

Note, if you are typically cold, maybe go with the Micropuf. For example, my girlfriend is habitually cold, and would require a Micropuff or Down jacket when Im wearing just a Tshirt and Thermawrap.

You can put another layer under, or over the Thermawrap of course, and the hoodless version will not interfere with that process. It has a great reputation here at BPL, just search for "thermawrap"

Jon, I own both a Thermawrap and Micropuff pullover. I was on a recent trip with a low around 40 and the thermawrap kept me warm enough, with an Icebreaker 200 mondo zip baselayer underneath. I assume you are asking for idle conditions off trail? I would not be able to hike in it. For my metabolism, I would favor the Micropuff when down to the mid 30's and below. I like to stay warm. The Thermawrap comes with a nice stuff sack, and compresses down slightly smaller than the Micropuff, to around the size of a 32oz plastic Nalgene bottle (it will compress more inside your pack too). My thermawrap has a full zip and pockets and weighs a couple of ounces less than the Micropuff. The Micropuff is a very purpose-driven garment, more warmth for the weight, with minimal features, ie, neck zip only and no pockets. Both garments work very well for for their intended use. Good luck with your decision. Andy

Many good comments here on the warmth qualities of the Thermawrap. I'll comment on one of my favorite features – the pockets. I wear my Thermawrap as my daily jacket around town as well as on the trail. The pockets on this thing are deep and cut in such a way that stuff won't fall out. Also, when you put your hands in there you feel as though they're really out of the cold as they can sit deeply enough in them to keep the cold off them.
