The MTEK FLUX helmet system

Innovation Defined.

Bono­wi intro­du­ces the FLUX hel­met , the latest in tac­ti­cal head pro­tec­tion. This is the tan­gi­ble result of a mul­ti-year design and deve­lo­p­ment effort to crea­te an advan­ced, modu­lar hel­met sys­tem. The word FLUX is an acro­nym for Future, Light­weight, Under­cut, eXpan­da­ble and is deri­ved from latin flu­xus, mea­ning “flow”. Every aspect of the FLUX has a very spe­ci­fic and deli­be­ra­te pur­po­se while main­tai­ning design con­ti­nui­ty- ever­ything “flowing” tog­e­ther. On the sur­face it may appe­ar to be a stan­dard hel­met, howe­ver once under­ne­ath, you’ll see it is like none other.

Advanced Geometry

The MTEK Flux helmet system follows the natural shape of the head

The first thing you noti­ce when put­ting on the FLUX is how it wraps around your head. One might argue that the outer shell geo­me­try is one of the most signi­fi­cant fac­tors in a helmet’s design. That is becau­se all other fea­tures must fol­low, in some form or ano­t­her, this main “refe­rence body”. The FLUX hel­met is spe­ci­fi­cal­ly desi­gned to fol­low the natu­ral shape of your head, so it results in incre­a­sed com­fort and sta­bi­li­ty, even when you wind up wea­ring it for hours on end or with mul­ti­ple access­ories atta­ched. This goes a long way to actively redu­ce men­tal and phy­si­cal fati­gue, espe­cial­ly when you don’t have time for eit­her. Hund­reds of varia­ti­ons and revi­si­ons went in to the FLUX shell design, becau­se to make a bet­ter hel­met, it all starts with a bet­ter hel­met shell.

The edge pro­fi­le of the FLUX shell is desi­gned to be ful­ly com­pa­ti­ble with all of your favo­ri­te com­mu­ni­ca­ti­ons head­sets, gog­gles, eye­we­ar, and respi­ra­tors. The rear pro­fi­le allows for pro­per clearan­ce when you’­re wea­ring a bal­listic vest and does not restrict move­ment even when lying in the pro­ne position.

The FLUX shell was desi­gned to clo­se­ly fol­low your head and has a noti­ce­ab­le under­cut to the outer shell. This devia­tes from the tra­di­tio­nal designs that have a ten­den­cy to “fla­re out” at the base of the shell. While this draft is bene­fi­cial for manu­fac­tu­ring, it’s not very con­sis­tent from a human fac­tors standpoint.

The bot­tom of the FLUX shell extends fur­ther down­wards and recur­ves into cen­ter. This lowers the rear moun­ting posi­ti­on of the reten­ti­on sys­tem, and allows the sus­pen­si­on sys­tem to fur­ther crad­le your head. This signi­fi­cant­ly adds to the over­all sta­bi­li­ty of the hel­met, espe­cial­ly when wea­ring lar­ge NOD’s or other moun­ted accessories.

Uncompromising Protection

Sta­te of the art mate­ri­als and pro­ces­sing tech­no­lo­gy are used to manu­fac­tu­re each and every FLUX hel­met. This is done in the pur­su­it of pro­vi­ding you the hig­hest per­forming hel­met sys­tem avail­ab­le today. For examp­le, addi­tio­nal car­bon fiber has been added to fur­ther incre­a­se the shell rigi­di­ty and impact per­for­mance of the FLUX Car­bon. For the FLUX Bal­listic, only next genera­ti­on poly­ethy­le­ne fibers are used, which gives it unpar­al­leled bal­listic pro­tec­tion. All of the­se things cost more than the alter­na­ti­ves. . Per­for­mance has it’s pri­ce and we’­re unasha­med. You don’t sett­le for good enough and neit­her do we. The best of what’s avail­ab­le goes into every FLUX hel­met, whe­ther it’s car­bon or ballistic

One shell, multiple helmets

If you choo­se to expand the pro­tec­ti­ve area of your FLUX hel­met shell, we’­ve got you cove­r­ed. The FLUX sys­tem has mul­ti­ple varia­ti­ons of ancil­la­ry side covers that give you several dif­fe­rent hel­met styles for the pri­ce and con­ve­ni­en­ce of one. The­se covers attach seam­less­ly under­ne­ath the side rail mounts, allowing for maxi­mum acces­so­ry space or “rail esta­te”. The covers were desi­gned to over­lap the shell edge pro­vi­ding you incre­a­sed pro­tec­tion should a frag­ment or slug impact any­whe­re along the seam. The covers, as well as the man­di­ble and visor sys­tem, will be avail­ab­le after the release of the FLUX Bal­listic hel­met. Like the FLUX shell, all ancil­la­ry com­pon­ents will be offe­red in impact (car­bon fiber) and bal­listic levels of protection.

100% Boltless shell

The­re are no dril­led holes or inserts through the FLUX hel­met to wea­ken the under­ly­ing bal­listic mate­ri­al. Poly­mer fas­te­ners replace all the hea­vy bolts, screws and other steel moun­ting hard­ware. Fas­te­ner strikes and secon­da­ry spal­ling are no lon­ger an issue. Light­weight retai­ning struc­tures are bond­ed direct­ly to the outer shell to allow for acces­so­ry rail and shroud remo­val. The end result is a safer, ligh­ter-weight helmet.

High ten­si­le strength struc­tu­ral adhe­si­ve per­ma­nent­ly bonds the poly­mer retai­ning struc­tures to the outer shell. Maxi­mum sur­face area bet­ween sur­faces yield excep­tio­nal bond strength and has out­stan­ding per­for­mance throughout a wide envi­ron­men­tal range.

The sus­pen­si­on and reten­ti­on are atta­ched to the shell inde­pendent­ly of any exte­rior fas­te­ners. If your mis­si­on requi­res abso­lu­te mini­mum weight this uni­que fea­ture allows you to strip the FLUX without nee­ding to sacri­fice bal­listic or impact protection.

Ther­mo­plastic anti-rota­ti­on inserts pro­vi­de you the opti­on to remo­ve your acces­so­ry rail if ser­vicing or main­ten­an­ce is requi­red. Should the total app­lied for­ce to the acces­so­ry rail exceed safe­ty limits, the fas­te­ners will fail, allowing the rail to break away from your hel­met shell pre­ven­ting neck or head injury.

Wilcox L4 Shroud

The L4 repres­ents what some would call the “gold stan­dard” of shroud design. It has a low pro­fi­le, anti-snag geo­me­try and fea­tures an ano­di­zed 6061 insert that accepts all of your opti­cal devices and came­ras. This rock-solid mount is pre­cisi­on manu­fac­tu­red by Wil­cox Indus­tries in their sta­te-of-the-art manu­fac­tu­ring facility.

The FLUX bolt-less con­fi­gu­ra­ti­on is main­tai­ned even with the Wil­cox L4 shroud. It is con­nec­ted to the front sup­port struc­tu­re with light­weight, ano­di­zed 6061 screws secu­red with nylon was­hers to keep the cover sta­ble and under pro­per ten­si­on. The three t‑nuts repre­sent the hig­hest “volu­metric mass den­si­ty” of any fas­te­ners con­tai­ned in the FLUX hel­met (basi­cal­ly, they’­re the hea­viest fas­te­ner of the hel­met). Their com­bi­ned weight is a litt­le more than four US one dol­lar bills (4.73g).


High strength poly­mers are used exten­si­ve­ly throughout the FLUX- in fact 68% of the FLUX Car­bon hel­met, and 96% of the FLUX Bal­listic con­sists of some type of poly­mer. As you can see below, the FLUX sys­tem con­tains a very low amount of metal. Actual­ly, when com­pa­ring total weight, less than 2% of eit­her hel­met con­sists of fer­rous or non-fer­rous metal. This equa­tes to sub­stan­ti­al weight savings making it one of the stron­gest, ligh­test-weight hel­mets avail­ab­le today.

FLUX Accessory Rails

Low pro­fi­le hel­met rails pro­vi­de the FLUX hel­met with an end­less array of poten­ti­al access­ories and attach­ments. The rails uti­li­ze the pro­prie­ta­ry Mag­pul® M‑LOK slots found on your favo­ri­te black rif­le. The­re are mul­ti­ple tie-down points avail­ab­le when rou­ting cables over or around the hel­met. The O2 clip port is com­pa­ti­ble with most exis­ting cen­ter release buck­les. The sta­ble 3‑point moun­ting sys­tem pro­vi­des a rigid, adap­ta­ble plat­form for moun­ting a varie­ty of access­ories and devices.

Built Tough.

The­se rails, like the rest of the FLUX hel­met, have been desi­gned for maxi­mum per­for­mance. They’­re mol­d­ed from a semi-crystal­li­ne aro­ma­tic poly­ami­de resin that ensu­res mois­tu­re and che­mi­cal resis­tance over a wide ran­ge of tem­pe­ra­tures and envi­ron­ments. Rein­for­cing ribs have been app­lied to all major stress points to fur­ther part rigi­di­ty and decre­a­se flex. All unne­cessa­ry mate­ri­al has been remo­ved from the rails and spa­cer to keep weight to an abso­lu­te minimum.

Fluxliner Suspension, Cam-Lock Retention

The Fluxli­ner™ gives the FLUX hel­met a soft, tailo­red fit and supe­ri­or sta­bi­li­ty that your old hel­met was mis­sing. It’s manu­fac­tu­red using a pro­prie­ta­ry rate-sen­si­ti­ve foam that has excel­lent impact per­for­mance. In addi­ti­on to the impact liner, each FLUX hel­met inclu­des two sets of mul­ti-thic­kness com­fort pads that allow you to mana­ge the inte­rior lay­out to get that per­fect, cus­tom fit. Cam-Lock reten­ti­on with Inver­se­clip® make for a hass­le free instal­la­ti­on and sizing. The back reten­ti­on moun­ting points have been lowe­red to the bot­tom extent of the shell for maxi­mum four-point sta­bi­li­ty. This design fea­ture allows for the eli­mi­na­ti­on of the nape strap, resul­ting in a sim­pli­fied, light­weight retention.

Impact Liner

Made from a pro­prie­ta­ry vis­co­elastic foam, the impact liner is desi­gned to pro­vi­de maxi­mum impact pro­tec­tion while pro­mo­ting air­flow through both car­bon and bal­listic ver­si­ons of the FLUX helmet.

Comfort Pads

The com­fort pads are repo­si­tion­ab­le and allows you to cus­tom fit the Fluxli­ner to the exact topo­lo­gy of your head. Each FLUX ships stan­dard with two sets of com­fort pad sizes ensu­ring a pre­cise fit.

Retention System

Maxi­mum hel­met sta­bi­li­ty is ensu­red by using a four-point reten­ti­on. Cam-Lock sli­ders allow you to quick­ly adjust the ten­si­on, even while wea­ring the hel­met. Chin cup is lined with sue­de lea­ther for incredi­ble comfort.

Featuring the Inverseclip®

With the Inver­se­clip® from Hel­met­Comp you can quick­ly and easi­ly remo­ve the harness from the FLUX hel­met shell. It con­sists of a two part design com­pri­sing of the wedge clip and the base, both manu­fac­tu­red from high-per­for­mance, engi­nee­ring gra­de poly­mer. The reten­ti­on sys­tem (web­bing) is con­nec­ted to the wedge clip, and the base is bond­ed to the inte­rior of the hel­met shell using the same high per­for­mance adhe­si­ve found in the outer shell retai­ning structures.
