X-Bionic Energy Accumulator Shirt - Long-Sleeve - Women's

The X-Bionic Women's Energy Accumulator Long-Sleeve Shirt compresses your muscle for greater power and distributes your body heat to keep you comfortable. Your body produces different amounts of heat in different places, especially when skiing, biking, or climbing. When you're hiking, your back gets hot and sweaty, then you stop and your back quickly becomes cold due to evaporation. The X-Bionic Energy Accumulator Shirt's Thermal Scan panels draw heat and moisture away from high temperature zones and spread them out over a large area to regulate your temperature. This heat-distributing technology and a compression fit combine to make X-Bionic one of the most technical, innovative base layers in the industry.

Bottom Line: The X-Bionic Energy Accumulator shirt uses advanced technology for enhanced performance, fit, and comfort.

Very good moisture control and thermoregulator

By: Eurystomus
November 18, 2007

I use this shirt for playing soccer, ultimate, and running outdoors as well as for hiking. It is excellent as a base layer for managing moisture as well as temperature control, without requiring heavy layers to retain heat. When wearing it, I stay far warmer and drier than when wearing other base layers. I purchased a L/XL, which fit well except for sleeves which were far too long for my arms. (I usually wear a M in most tops, except tight tops, when I usually wear a L.)

Nothing like it

The whole X-Bionic system is unlike anything you've tried before. Don't be scared by the price here, this product is unparalleled for baselayers. There is a complex air-conditioning, channel system in this stuff that assists in keeping warm and dry but not overheating. You won't need to keep any of your other baselayers around. This is a bit compression but in no way is it uncomfortable. For me, I teach skiing all day and often spend my evenings volunteering with Search and Rescue. I don't usually have time to go home and change or put a warmer layer on as the sun sets and this stuff will keep me warm no matter what. The other best part is that I don't have to wash it a ton because it is anti-microbial and doesn't stink. To find this kind of structural support, warmth, comfort, and quality you would need to search far and wide. The price is on the high end but worth every one of your pennies and more. I recommend this product to everyone who does any type of winter/outdoor activity.
