Composite Vest

The Composite Vest is a heavy mid-range armour included by IC2. It provides 9 armour points (4.5 armor symbols on the HUD) which is greater protection than vanilla's Diamond Chestplate. It also lasts far longer; with a capacity of 801 durability points compared to Diamond's 529, this makes it superior to any vanilla armour currently available.

Recipe
To note, with GregTech enabled the composite armour is considered less worthwhile because of the increased cost of manufacturing Mixed Metal Ingots to acquire Advanced Alloys
