Description

The Anon Kids' Define is a kids' ski and snowboard helmet with its goggle built in, aimed at families tired of goggles that slide, fall off or get left in the car. Anon pairs an Endura ABS hardshell with a rear BOA dial (its Youth 180° system) and a magnetic Fidlock buckle, and the goggle frame leaves room for prescription glasses underneath.

Anon's Strapper-Keeper makes the goggle part of the helmet and keeps its strap lined up, so a young skier has nothing to fasten or find. The dial sits in the helmet and tightens the back half of the fit, fixed vent channels backed by snow stopper fabric move air through, and fleece covers the liner and ear pads. A protective tote bag comes in the box.

Anon publishes no tint or VLT for the goggle and makes the Define in Regular fit only.

No standard appears on the product page, but the EU declaration Anon files for the Define cites EN 1077:2007, and Anon's helmet guide gives EN 1077 Class B and ASTM F2040 for all its helmets. In L/XL it fits a 52–55 cm head. We can help you measure and check how the goggle sits before you buy.

Anon Kids’ Define Helmet

Define family · 26/27

Anon logo

Technology

Strapper-Keeper

Anon’s integrated-goggle design: the goggle is built into the helmet and its strap stays aligned, so there is nothing to attach or re-attach.

Youth 180° BOA® Fit System

A fit dial built into the helmet makes micro adjustments across the rear half of the head.

Endura® Shell

An injection-molded ABS exterior that Anon uses for long-lasting durability and ding resistance.

Fidlock® Magnetic Buckle

Magnets let the buckle open and close with one hand, even with gloves on.

Passive Ventilation

Fixed channels bring air in at the front and pull moisture out the back, with snow stopper fabric keeping snow out of the vents.

Over-the-Glass Goggle Frame

The built-in goggle’s frame is designed to accommodate prescription eyewear underneath.

Features

  • ·Goggle built into the helmet (Strapper-Keeper)
  • ·Goggle frame designed to fit over glasses
  • ·Youth 180° BOA® dial
  • ·Fidlock® magnetic buckle
  • ·Fleece liner and ear pads
  • ·Protective tote bag included

Anon’s Kids’ Define is worth buying when the goggle is the problem: a child who loses, forgets or fumbles goggles, or one who skis in prescription glasses.

The Kids’ Define gives up lens choice: with no lens data published for the built-in goggle, you cannot pick a darker or lighter lens when you buy it, as you could with a separate goggle.

The Kids’ Define’s fit is dial-driven, but only at the back. Anon’s Youth 180° BOA makes its adjustments across the rear half of the head, where the Kids’ Burner’s 360° BOA works around the full circle, and the Burner leaves the goggle choice to you. With no Round Fit version of the Define, a rounder head has no alternate shape within this model.

If lens choice or a round head shape matters more than a goggle that stays on the helmet, skip the Kids’ Define and pair a separate helmet and goggle instead.

Safety — read this

Anon’s own helmet guide says certifications and protection inserts may allow a better level of protection, but nothing is absolute. With the goggle attached, check that it sits on the face without pressing the nose once the BOA dial is set, and remember that Anon calls a helmet that shifts side to side or front to back too big. Inspect the helmet after any crash and retire it if in doubt, because damage may not be visible.

Common Questions

What certification does the Anon Kids’ Define have?
The product page names none. Anon’s EU Declaration of Conformity for the Define lists EN 1077:2007, the European standard for alpine ski and snowboard helmets, and Anon’s helmet guide says every Anon helmet carries ASTM F2040 and CE EN 1077 Class B.
Can kids wear glasses under the Kids’ Define goggles?
Anon says the goggle frame is designed to accommodate prescription eyewear underneath. Glasses frames vary, so try the helmet on with your child’s own glasses before the first ski day.
What is the difference between the Kids’ Define and the Kids’ Rime 3?
The Define builds the goggle into the helmet and fits with a Youth 180° BOA dial, in Regular fit only. The Rime 3 has neither a dial nor a built-in goggle; it uses an elastic rear closure, carries Anon’s multiseason wording and comes in Round Fit as well as Regular. Both use an Endura hardshell and a Fidlock buckle.
What size is the Kids’ Define L/XL?
Anon’s kids’ size guide lists L/XL at 52–55 cm head circumference, and the Define comes in Regular fit only. Measure around the head about one inch above the eyebrows, then snug the BOA dial once the helmet is on.
What comes with the Kids’ Define?
Anon says the Define includes a protective tote bag, and the goggle comes attached to the helmet through the Strapper-Keeper design.
