Aah ... but now Alexium have met all the requirements that the Marines had for FR on uniforms - and they were a number.
Its not as if we are trying to win a tender with a number of other companies all submitting the best they can in terms of the Marines requirements but all not meeting everything the Marines require.
So really it may be now more a case of the Marines running their tests and confirming that their requirements are met [which Alexium have already done in-house].

The Marine Corps wants to upgrade its combat utility uniform, a move officials say could save the service millions of dollars and provide wearers with better protection in the field.

Marines currently have two separate utility uniforms they wear outside tropical environments: the digital-patterned combat utility uniform and flame-resistant organizational gear, known as the FROG combat uniform. The combat utility uniform provides signature mitigation, designed to camouflage a Marine from possible enemy detection, but no flame protection. The FROG gives flame protection and signature mitigation, but it's significantly more expensive, officials said, and not as durable or comfortable as the combat uniform.

"A single-issued uniform with these protection properties will allow the Marine Corps to focus on optimizing funds and streamline the acquisition process while providing maximum protection and comfort to its servicemembers," a solicitation updated this month by Marine Corps Systems Command states.

The next-gen uniform will still look the same as the one Marines wear now, said Kelly Flynn, who is with the command. But with each combat utility uniform running $89 apiece and the FROG uniform costing another $184, Flynn said there is money to be saved.

"Value is in a reduction of the logistic burden of maintaining separate FROG combat uniforms," Flynn added. "The Marine Corps expects a cost saving of a few million dollars due to not having to buy replacement FROGs."

"The preeminent goal of the Marine Corps is to modify the existing [Marine Corps combat utility uniform] in order to provide a durable uniform to every Marine that provides [fire-resistant] protection and spectral mitigation properties across visual, [near infrared], and Shortwave Infrared (SWIR) wavebands without a significant increase in cost," the request for information states.
