PolarTec is a registered trademark and has recently been purchased by a company named Mill Textiles and they have continued to manufacture the 100, 200, & the 300, still under the PolarTec name.
The jacket that you are referring to is a very very nice jacket for $30.00 I have two of them and if you do wear a good decent base layer this jacket can keep you warm in some pretty nasty temps...The 200 is designed to wear as an outer layer because it has all kinds of outside pockets like hand warmer pockets and such. I have a bright yellow one and a dark green one. They are both very warm and well worth the $30.00 bucks.. If you go to (Millstextiles.com) you can find all of the products that were once made by the PolarTec Company.... They manufacture some very high tech materials and they are very functional too. Can't beat PolarTec for staying warm (and dry) by using the correct layering.. I use the 100 (tops & bottoms) to sleep inside my sleeping bag and it really helps to raise the temp of you bag regardless how high or low it is rated....Hope this helps...Happy Trekking....sabre11004
