SUMMARY

These professional RefrigiWear Endurance Drive extreme cold salopettes are the benchmark equipment for engineers and technicians operating in climatic chambers. They combine certified 220 g thermal insulation (guaranteeing consistent, even warmth down to -34 °C) with an ultra-resistant 600-denier outer fabric.

Designed to never hinder your precision work, they slip on easily over your clothes thanks to side zips extending up to the knee. The elastic braces and side stretch panels ensure a perfect fit while in motion. Adjustable fit, available from S to 5XL.

A true thermal suit of armour, designed to allow you to stay 100% focused on your tests and measurements, without ever worrying about dropping temperatures.

PROFESSIONAL ENVIRONMENT Engineering & Climatic Chambers

The thermal guarantee for precision professionals

When taking precision readings or conducting tests in a climatic chamber at -30 °C, thermal discomfort is not an option: it impairs concentration and compromises the duration of procedures. Designed by RefrigiWear (the American leader in thermal protection since 1954), the Endurance Drive salopettes are a true technological suit of armour. Their 220 g quilted polyester insulation ensures exceptional heat retention, while the 600-denier outer shield protects against abrasion in industrial environments. Functional and ergonomic, they have been designed to layer quickly over civilian clothing and guarantee absolute freedom of movement during your interventions.

The Extreme Cold Expert's Opinion

In high-value professions (engineering, R&D, aerospace testing), cold is the worst enemy of human reliability. If a technician's back gets cold while bending over equipment, they will cut their intervention short. The strength of these salopettes lies in their complete sealing of the lumbar zone. They can be slipped on in seconds over work trousers using the side zips, instantly insulating the operator from their environment. This is the trusted PPE for teams who must remain completely focused on their tests, not on the thermometer.

What are they for?

The Endurance Drive is aimed at professionals whose duties require infallible thermal protection in controlled environments.

Climatic chambers and laboratories: for conducting prolonged environmental and aging tests at very low temperatures.
Research & Development (R&D): stationary procedures or handling of precision instruments in freezing atmospheres.
Aerospace & Automotive sector: cold wind tunnel testing or component development under simulated winter conditions.
Pharmaceutical and cryogenic industry: maintenance of complex refrigeration systems requiring high mobility.

The secret of insulation: Still air

Insulation does not come from the fabric itself, but from the volume of air it manages to trap around your body. The 220 g of quilted polyester builds this layer of static air between the lining and the outside, blocking the transfer of cold. But the real technical feat lies in the very structure of the salopettes: by completely eliminating the break at the waistband (the weak point of classic trousers), they prevent any warm air from escaping, even when the technician crouches or bends over their equipment.

Technical specifications

Warmth: High-performance 220 g quilted polyester insulation for even heat distribution.
Inner lining: 100% polyester, amplifies thermal retention and makes slipping them on easier.
Outer shield: Ultra-resistant 600-denier technical fabric to withstand industrial abrasion.
Ergonomic fit: Adjustable elastic braces and stretchy side panels for a perfect hold.
Quick dressing: Side zips extending up to the knee, designed to fit over safety boots.
Practicality: Press studs at the hem to adjust the leg length.
Reinforced protection: Curved anti-abrasion knees with integrated pockets for knee pads.
Reliability: YKK zips, globally renowned for their resistance to extreme cold.
Comfort: 2 lined handwarmer pockets to protect extremities between handling tasks.

Size guide

Straight fit with adjustable braces. Measure your waist circumference and inside leg directly in centimetres.

Size	Waist size (cm)	Inside leg (cm)
S	71 – 76	76 cm
M	81 – 86	76 cm
L	91 – 97	77 cm
XL	102 – 107	79 cm
2XL	112 – 117	80 cm
3XL	122 – 127	81 cm
4XL	132 – 137	82 cm
5XL	142 – 147	83 cm

Pro equipment advice: If in doubt between two sizes, opt for the larger one. Slightly loose salopettes promote warm air circulation and will slip more easily over work trousers and thermal underwear.

Care instructions

Washing: Cold wash only (delicate cycle).
Warning: No fabric softener! Softening agents deteriorate the polyester fibre's thermal retention capabilities.
Drying: Must be dried flat. Do not use a mechanical tumble dryer.
To avoid: Ironing and dry cleaning are strictly prohibited.
Spot cleaning: Clean local stains with a damp cloth without rubbing aggressively to preserve the fabric coating.

Maximise your protection in the laboratory: The layer system

The Endurance Drive salopettes are the central element of your insulation, but their effectiveness relies on the quality of the layers accompanying them.

Acclimatisation: Put the salopettes on directly in the airlock of the cold room, not in a heated office. The body will acclimatise better to the thermal transition.
Base layer: Always wear technical thermal underwear (top and bottom) next to the skin. It will prevent the feeling of cold caused by micro-perspiration from exertion.
Complete outfit: For extreme and prolonged exposures, combine these salopettes with the Endurance Drive 8212R Jacket to ensure a hermetic barrier from head to ankle at -34 °C.

* Indicative thermal rating (-34 °C). The intensity of your metabolic activity, the duration of your tests, and the layering of your thermal clothing directly influence the perceived warmth.
