Buying thermal gear for a team: an employer's bulk purchasing guide
To buy cold weather gear for employees in bulk, start with a needs assessment by job, not a single catalog order. Run a sizing session and a short wear trial, send suppliers a written spec sheet, then negotiate minimum order quantities, warranty, returns and replacement terms. Plan laundering and, for battery-heated items, a controlled charging area before the first box arrives.
What should you decide before asking suppliers for quotes?
Group workers by exposure, not by department. A driver moving between dock and freezer and a guard standing at a gate need different garments. For each group, note the coldest conditions, how long people stay in them, how active the work is and what other PPE must be worn.
This is also what OSHA's PPE standard expects. Under 29 CFR 1910.132(d), employers assess the workplace for hazards, select protection for each affected employee, communicate the selection and select PPE that properly fits each worker. Write it down as a matrix by job; every later decision refers back to it.
| If the job involves... | Specify first | Watch for |
|---|---|---|
| Standing still in the cold (gates, flagging, inspection) | Core insulation or a heated or warmer-pocket vest under the shell | Hi-vis must stay on the outside and uncovered |
| Moving between warm and cold zones | Layers that come off quickly, such as a vest over a base layer | Sweat that chills after exertion |
| Artificially cold rooms such as freezers | Freezer-rated insulated outerwear, gloves and footwear | Payment rules differ from outdoor weather gear |
| Harness, tool belt or body armor | Low-profile layers that sit flat | Pockets, cables or bulk under straps |
Do employers have to pay for winter gear?
Under 29 CFR 1910.132(h)(1), protective equipment used to comply with OSHA's standards must be provided at no cost to employees. Paragraph (h)(4)(iii) then excepts ordinary clothing and other items used solely for protection from weather, such as winter coats, jackets, gloves, parkas, rubber boots and hats.
The exception has limits. In the 2007 final rule, OSHA explained that when ordinary weather gear is not sufficient and extraordinary clothing is needed for unusually severe weather, the employer must pay, and that clothing used in artificially controlled environments with extreme cold, such as freezers, is not part of the weather gear exception. State plans can add requirements.
How do you run a sizing session and wear trial?
Ask shortlisted suppliers for a size run: one of each size in each style you are considering. Have workers try them over their real base layers and under the outerwear, harnesses and hi-vis they must use, then record size and whether they can reach, kneel and climb comfortably. NIOSH notes that tight-fitting PPE can raise frostbite risk and that loose layers insulate better, so err toward room to layer.
Then run a wear trial with a small group from each job profile over real cold shifts, using a one-page form for warmth, fit, dexterity, washing and, for heated items, runtime. Use the results to set your size curve rather than guessing from a generic chart.
What should a spec sheet to suppliers include?
A written spec sheet makes quotes comparable and protects you if production differs from the sample. Send every supplier the same fields.
| Spec field | What to ask for |
|---|---|
| Garment type and style code | Exact model, color and whether the sample matches production |
| Size range and fit | Full size chart, women's cuts, tall or big sizes, and garment measurements |
| Materials and insulation | Shell, lining and fill, weight, and water or wind resistance |
| Compatibility | Fit under hi-vis, flame-resistant or arc-rated clothing, harnesses and duty gear as your assessment requires |
| Heating system (if any) | Battery chemistry, voltage and capacity, charger model and battery test standard documentation |
| Care instructions | Wash and dry method, battery removal, and whether industrial laundering is allowed |
| Commercial terms | MOQ per style and color, unit price breaks, lead time and reorder time |
| Warranty and returns | Warranty length, what it covers, defect process and size-exchange policy |
How should you handle MOQs, warranty and returns?
Minimum order quantities usually apply per style and color, and custom colors or embroidery raise them. Reduce the number of styles rather than overbuying odd sizes, and ask whether sizes can be mixed within an MOQ. Confirm reorder lead times too, because cold snaps drive demand across a region at once.
Get warranty and return terms in writing: how defect claims work, who pays return shipping, whether batteries carry a separate warranty and how many size exchanges are allowed. Hold back a small stock of common sizes for new hires and exchanges.
How often should thermal gear be replaced and laundered?
Set replacement cycles by condition, not by calendar alone. Inspect garments at the start of each cold season and retire items with torn shells, flattened insulation, failed zippers or damaged heating wires. NIOSH notes that insulation loses effectiveness when wet, so worn-out water resistance is a real reason to replace.
Decide early whether gear is personal issue or pooled. Pooled gear needs a laundering process that follows each manufacturer's care label, and heated garments need batteries removed and connectors protected before washing. A supplier without written care instructions is a warning sign.
How do you set up battery charging and storage safely?
Battery-heated gear adds a charging program to your purchase. OSHA's safety and health information bulletin on small and wearable lithium battery devices recommends batteries and chargers tested to an appropriate standard such as UL 2054, following the manufacturer's charging instructions, removing devices from chargers once fully charged and storing batteries in dry, cool locations.
In practice: a designated charging station away from combustibles, only the manufacturer's chargers, numbered packs, and inspection before issue for bulging, cracking, hissing, leaking, heat or smoke. OSHA advises placing damaged batteries in a fire-resistant container, such as a metal drum with sand, and disposing of them according to regulations. Replacement batteries should come from the device manufacturer or an authorized reseller.
Where HEATJAC fits
HEATJAC CORE is a low-profile thermal harness platform with integrated heat-reflective thermal inserts and pockets that accept supplemental warming elements such as air-activated warmers, or cold packs for cooling (sold separately). It is passive, with no built-in battery, so it adds no charging program, and it comes in S/M and L/XL. It suits layered programs where a thin core layer must sit under outerwear or hi-vis; it does not replace insulated outerwear for freezer or severe outdoor work.
Key takeaways
Build a needs matrix by job before requesting quotes; it drives every later choice.
OSHA generally excepts ordinary weather gear from employer payment, but not freezer clothing or extraordinary gear for severe conditions.
Use size runs and a short wear trial to set your size curve.
Send every supplier the same written spec sheet and get warranty and return terms in writing.
Budget for laundering, replacement and, for heated gear, a controlled charging station.
Frequently asked questions
Are employers required to provide winter coats?
Generally no. OSHA's PPE payment rule, 29 CFR 1910.132(h)(4)(iii), excepts ordinary clothing used solely for weather protection, such as winter coats, jackets, gloves and hats. The exception does not cover clothing for artificially cold environments such as freezers, or extraordinary gear for unusually severe weather.
How many sizes should we order for a crew?
Base the size curve on a fitting session with a supplier size run, not on a generic chart. Hold a small reserve of the most common sizes for new hires and exchanges, and ask whether sizes can be mixed within the minimum order.
Should thermal gear be personal issue or pooled?
Personal issue usually fits better and is looked after better. Pooled gear can work for visitors or occasional tasks, but it needs a laundering and inspection process that follows each manufacturer's care instructions.
What documents should a heated gear supplier provide?
Ask for battery and charger test documentation, written charging and care instructions, a full size chart and the warranty terms, including any separate battery warranty. OSHA recommends batteries and chargers tested to an appropriate standard such as UL 2054.
How long should a wear trial last?
Long enough to cover real cold shifts, laundering and charging cycles for each job profile. A few weeks in genuine winter conditions usually reveals fit, warmth and durability problems that a fitting room will not.
