Hi There. I think I can answer your question. There is no difference in the type of support you will get between the CW-X Stabilyx tight and the CW-X Insulator Stabilyx tight. The main difference is in the fabric. The non insulated Stabilyx tight is constructed of Coolmax which is a great overall athletic material that breathes and wicks away moisture. The Insulator version is made from a proprietary nano-tech Temperature regulating material called Autosensor. This material feels slightly thicker than coolmax and has a brushed micro fleece feet on the inside. The Autosensor material is designed to sense the temperature outside vs your skin temperature. If your skin temperature is cold, the material forms a thermal barrier and traps heat while you warm up. Once the temp reaches about 81 degree F the material starts releasing heat keeping you at an optimal temperature during exercise. The other main difference in the tights is that the Insulator Stabilyx Tight has wind blocking material on the quads. Great for colder or more windy days. Bottom line is that now we are in October, the Insulated Stabilyx Tight may offer you enough temperature flexibility but you will be able to use it once the temps get cold. Also it's a great underlayer for Snowsports like Skiing, snowshoeing, Tele, etc. Hope this helps.
