Gear that holds up when the temperature drops

Tecbro builds cold-weather workwear for crews who cannot stop when the weather turns — freezer floors, winter sites, night shifts and open ground. Every Chill-Bloc piece is tested for warmth, movement and wear before it reaches the catalog.

Home page / About us

We keep crews working when it gets cold

Whatever the weather or the shift pattern, we build for it.

About us

Genuine, responsible and built to last

Tecbro exists because the people who work through winter were being sold clothing designed for looking at winter. We build cold-weather workwear for freezer floors, night maintenance, winter sites and open ground — and we test every line on a working crew for a full season before it reaches the catalog.

That means fewer products, released more slowly, with the ones that failed quietly removed. It is a slower way to run a catalog and a better way to run a crew.

Our core values
Quality products

Every recommendation comes from a crew that wore the garment for a season, not from a spec sheet.

Custom branding

Embroidery and heat transfer on any line, with artwork proofed before a single unit is run.

Competitive price

Trade tiers from ten units and 30-day terms, because kitting out a crew shouldn't need a purchase order per person.

“We are on a mission to make cold weather a non-event for the people working through it.”

Size guide

Our sizes run tighter than most workwear because the insulation is cut close. If you plan to layer underneath, take the next size up.

Apparel — coveralls, bibs & jackets

SizeChestWaistSleeve
{{ r.size }} Chest{{ r.chest }} Waist{{ r.waist }} Sleeve{{ r.sleeve }}

Gloves

Measure around the knuckles of your dominant hand, excluding the thumb. S fits 7–7.5 in, M 8 in, L 8.5–9 in, XL 9.5–10 in, 2XL 10.5 in and up. If you are between sizes, go up — a tight glove is a cold glove.

Headwear

Balaclavas, gaiters and headbands are one size and stretch to fit 21–24 in head circumference. They are cut flat-seam to sit under a hard hat without pressure points.
