For maximum performance in cold weather conditions when playing airsoft or doing some tactical operations, you might want to look into this jacket from UF PRO... "For the worst possible outdoor conditions, the Delta AcE Plus jacket provides excellent comfort properties, maximum wind protection and permanently water repellent thermal insulation.

Best possible thermal insulation and heat management

In order to reliably protect the temperature sensitive upper and lower arms against cold temperature, the sleeves are lined with G- Loft thermo insulation lining. Additional weather protection is provided by a permanently water resistant and windproof outer material of the sleeves.

For an efficient moisture management, the sides, the contours of the back and the armpit areas are made out of 37.5™ micro fleece from COCONA® Inc.

Reliable shield against wind chill

Protection against cold wind is provided with a two layer nylon ripstop, PU membrane laminate lined with the 37.5™ micro fleece.

UF PRO® air/pac® comfort in the upper back and shoulder areas

A significantly increased wear comfort is achieved by air/pac® inserts in the shoulder and upper back areas. They offer enhanced air circulation and additional thermal insulation without increasing weight or reducing breathability.

Sizing

Please note that this is a very slim fitting product. If you are at the upper limit of a size, then we suggest that you rather choose the bigger size. Example: If your chest circumference is 103cm, then you could already wear size XL."
