ESS Crossbow review: the issued eyeshield, and why the SKU you buy changes what the page promises

One frame, several kits

ESS sells the Crossbow as a 2LS kit (frame with smoke lens, plus a clear lens), a 3LS kit, a Suppressor variant with thin temples for comms, and an APEL kit — "Crossbow Black 2x w/Clear & w/Smoke Gray APEL", SKU 740-0386, which ships two fully assembled eyeshields, a hard case and a pouch. The frame and the ballistic lens are the same product line across all of them. The rating statement on the page is not.

The rating, page by page

The APEL kit page lists "ANSI Z87.1+ 2015 Edition", "U.S. MIL-PRF-32432A", "U.S. Federal OSHA", "CE EN 166" and "APEL (Authorized Protective Eyewear List) approved". The 2LS kit page lists "ANSI Z87+ 2020", "CE EN 166", OSHA and a "Battle Rated" badge, with no MIL-PRF number printed. That is not ESS being coy; the APEL listing belongs to a tested configuration, and ESS labels the SKU that carries it. Our rating column shows the Crossbow as APEL because the APEL kit page states it, and the card's Evidence table cites both pages so you can see which said what. What an APEL listing proves is on the APEL guide.

DedBolt and the lenses

The "patented DedBolt Lens Lock" is ESS's tool-free swap: the lens locks into the frame at the bridge and releases with a pull. The 2LS kit ships smoke gray fitted and clear in the box — the two tints that cover a bright field and an indoor bay. Hi-Def yellow and other tints are sold separately and on the 3LS kit. ESS describes the optics as "distortion-free" ("ESSOPTICS") without publishing an optical class. What to swap to, and when, is on the lens color guide.

ClearZone FlowCoat

ESS names its coating and describes it: "ClearZone FlowCoat technology minimizes scratches and provides unmatched anti-fog capability". A named coating with a stated function is worth more than a bare "anti-fog", and it is why the Crossbow ranks ahead of the ICE on a warm indoor bay. It is still a coating, not a dual-pane lens; the ranking of fixes is on how to stop shooting glasses fogging.

Three inserts

"Prescription compatible with the ESS U-Rx Insert, ESS Vice Insert, and UPLC." Three documented routes to put a prescription behind the ballistic lens, which keeps the rating in front of your eyes and the prescription out of the impact path. This is the single strongest reason to choose the Crossbow over a pair whose page does not mention Rx at all. The routes are compared on Rx inserts vs prescription lenses.

Tri-Tech Fit and the one-size caveat

ESS calls the frame "Tri-Tech Fit" and "Universal Fit": a frame designed to sit on most faces without pressure points. Universal is a promise and a limit. On a narrow face or a child, one size means the temples splay and the wrap sits off the cheek; Revision sells the Sawfly in Small for exactly that buyer, and the youth frames are on youth shooting glasses. Nothing on the Crossbow page describes the temples for ear muffs; the ultra-thin Suppressor frame exists for exactly that, compared with this kit on Crossbow vs Suppressor, and the ICE has the telescoping temples.

What ESS does not publish

• Lens material and thickness (polycarbonate is stated for the ICE and Crosshair, not on the Crossbow pages we read).
• Weight.
• Frame dimensions.
• Warranty terms on the product page (linked separately).
• UV figure on the Crossbow pages (stated as 100% UVA/UVB on the Crosshair and ICE pages).

The alternatives

Against the Oakley SI Ballistic M Frame 3.0, see Oakley M Frame vs ESS Crossbow; against the Wiley X Saber Advanced, Wiley X vs ESS.

The comparison most people make next is against the smaller frame in the same line, which states the same ballistic standard but publishes less about its coatings: ESS Crossbow vs Crosshair.
