The award winning Forcefield Pro Sub 4K back protector was designed to withstand greater impacts than any other motorcycle back protector currently available and at just 3.38kN transmitted energy when subject to the CE test EN1621-2 Level 2.
Introducing the Pro Sub 4K - Now with Kevlar and a new look!
Back in 2009, the Forcefield Pro Sub 4 was launched. The first motorcycle back protector to pass the CE 2 test at below 4kN*. The official test pass was 3.38kN. A world first, and industry award winner.
Even today the Pro Sub 4 still holds the accolade of being the most protective motorcycle back protector available. That is some record!
The NEW Pro Sub 4K still passes the CE 2 test at this amazingly high protection level; it has the Forcefield DRI-M Technology (Dynamic, Reactive, Intelligent Materials) integrated throughout.
It fits close to the body, 3D custom moulding to the wearer’s shape. It has the ability to withstand multiple impacts, and contains hundreds of breathable vent holes throughout to help maintain body temperature.
The multi-layered technical materials are now held together with Kevlar thread for added security and strength. These sit in a refreshed, removable cover that can be washed and kept clean.
The Pro Sub 4K has been engineered to offer the maximum in terms of safety and protection, yet is super comfortable and extremely durable.
The reason the original Pro Sub 4 has stood the test of time is the versatility that this product gives. It can be used on road, on track, touring, super moto and adventure.
Still the same industry leading great product, now stronger, and with a new, fresh appearance.
*4kN is considered by experts to be the maximum amount of transmitted energy that should be subjected to a human to prevent severe back and rib trauma.

Review on Forcefield Pro Sub 4k BackprotectorBy: T P Hillbom on 5 July 2019I purchased this back protector when upgrading all my armour to CE2 level recently. The Pro Sub 4k replaced an older model Forcefield back protector. I am happy to say I am very pleased with my purchase. It is really comfortable (like all Force field products), have heaps of adjustability and offers superior protection level compared to all other competitors in the market. It should be noted that it is thicker than your normal back protector and if you are e.g. wearing a leather jacket you might want to check first so it fits under your jacket. Having said that, I use mine under a Merlin kevlar shirt and it is very comfortable. I don't notice it when riding. As all Forcefield products I own the quality is excellent. It is easy to see/feel that it beats all other brand in terms of protection offered. I am very happy with my purchase.
