Forcefield Base Layer Shirt

Inspired by Geothermic Phenomena observed on Earth the Forcefield Base Layer Shirt has been created using BeCool™ the first polyamide fibre with integrated airflow control a function that maintains body temperature during sports and leisure activities. Through a four chanelled thread BeCool™ has a greater diffusive area than standard thread, upto three times greater than cotton, which allows it to act like a fan forcing the skins hot and humid air towards the outer layer of the fabric while allowing cool and dry air to circulate from the outside into the surface of the skin.

It is further enhanced by its softness, lightness and silky touch creating a cool freshness to the skin combined with seamless and flat seam technology to ensure that the fabric does not rub or chaff during activity. The Forcefield Base Layer also has an antibacterial element built within to help maintain freshness.

Fits well I bought the shirt for a toys for tots run. Needed a good base and this fit the bill. Nice product and satisfied with the performance. January 27, 2015
Shirt works as advertised I bought this to wear under my race leathers. It works great both in the heat and the cold. It seems to insulate as well so not just for hot weather. Its a great base layer too in cold temperatures and keeps you warm. Okay, its a little pricey but you get what you pay for. Snug compression fit, but fits true to size. December 9, 2013
Nice base layer Purchased this for my wife's track use under her suit. 'm familiar with Forcefield products and this looked worth a try. It appears to run slightly smaller than the advertised sizes. Revzilla was very helpful in the return process to go a size up. I have Dianese and RS Taichi underlayers and this looks to be equivalent to those. My wife has yet to take it to the track to verify air flow but the fit is comfortable under her suit. Looking forward to track testing it. April 1, 2013
