Ergodyne Chill-Its 6670CT Hard Hat Sun Shade — Clip-On Evaporative Neck Cooling

The Ergodyne Chill-Its 6670CT covers the strip of skin every outdoor trade sacrifices to the sun: the back of the neck. Clip it to the hard hat, soak it if you want active cooling, and the shade rides wherever the lid goes — sun protection and evaporation in one attachment, in hi-vis lime that doesn't break the visibility scheme.

Why a hard hat sun shade earns its clip

Hard hats solve the face and forget the neck: heads-down work — paving, roofing, surveying, framing — points the one unshaded strip of skin straight at the sun for eight hours, and it burns on repeat all season. A clip-on hard hat neck shade fixes the geometry at the source, riding the shell so coverage follows the work instead of depending on reapplied sunscreen. The 6670CT adds the family trick on top: soak the panel and evaporation actively cools the same strip it shades. Our full 6670CT review scores it; the best cooling gear guide maps the head tier.

What the listing documents

From the listing: clips to a hard hat and drops an evaporative cooling shade over the neck — the body part road crews and roofers burn first; sun protection and evaporative cooling in one attachment; hi-vis lime that keeps the visibility story intact; size and color options on the linked Amazon page. It's the counterpart to a brim-style hard hat sun visor: the visor extends the face's shade, this covers the rear exposure.

Picking inside the hard-hat comfort family

Outside the shell versus inside it: this shade and its hot-work twin — the FR-rated 6717FR for welding and grinding zones — mount to the shell, while the suspension side runs the 6612 crown pad, the fuller 6614 sweatband kit, or the 6715CT evaporative insert when the crown wants active cooling. Shade plus pads turns a bare lid into full hard hat sun protection for a few dollars per head.

The rest of the summer kit

Below the brim, the neck-and-core system takes over: the 6602 towel, its microfiber sibling, the 6700CT bandana, or machine-side 6603 wrap for the neck, the premium 6685 for documented-exposure programs, and the vest tier for the core — 6665 for general crews, full-PVA 6667 for output, phase-change 6260 for humidity. The lid gets chosen per the selection guide, hot-work picks, and 2026 rankings; summer visibility runs the hi-vis shirt roundup.

Ownership and crew deployment

Rinse it, dry it, store it dry — stiffness when dry is normal evaporative behavior — and retire it when the panel tears or the clips crack. Issue one per hard hat in the summer kit for heads-down trades: at this price the shade costs less than the aloe. The full shelf lives in the cooling gear collection. For crew-scale orders, quantity purchasing runs through a free Amazon Business account — the walkthrough is linked in our footer.
