Mens CoolLife Sleepwear
Sleep Cooler and More Soundly.
Our featherlight, soft-as a-cloud Sleep Top is designed and tailored for ultimate comfort and backed by science to improve your sleep. CoolLife technology works all night long, letting your body heat escape and regulating your body temperature for a perfect rest.
LifeLab's barely-there Sleep Bottom continuously cools your core temperature throughout the night, so you can sleep better, use less energy and combat climate change before the sunrise.
Why We Like It:
- Continuously moves your body heat away from your skin, keeping you 1.1C/1.9F cooler
- Studies show that maintaining the right temperature during the night helps lead to a more restful sleep
- Production of this set emits 61% fewer CO2 emissions, cuts water pollution by a third, and uses 58% fewer fossil fuels than typical non-recycled nylon
The world is warming at an alarming rate. People need ways to stay cool without depending on heavy energy drains such as air conditioning, which accounts for about 12% of our collective energy footprint. We asked ourselves: how can our clothes help keep people cooler and more comfortable in a changing climate?
The world’s first thermally transparent fabric. CoolLife is the only infrared-transparent fabric that releases virtually 100 percent of your body heat and cools your body temperature by two degrees.
Polyethylene (PE) is the most sustainable among natural and synthetic textiles in the world, according to the Materials Sustainability Index.
Engineering PE fibers use less energy and water than traditional materials. They can be solution dyed and dry extruded, resulting in additional water savings.
CoolLife delivers more effective cooling with less environmental impact for a uniquely cooler, drier, more comfortable experience.
CoolLife’s infrared transparency allows your body heat to escape and your body temperature to drop, creating a continuous cooling effect unlike any other apparel. Polyethylene, a sustainable, recyclable polymer, transfers body heat away from the skin more efficiently than any other performance fabric in the world.

Our CoolLife Sleep Top is constructed with 41% recycled materials by fabric weight.
We use 100% recycled polyester labels and sewing thread.
We reduce our environmental footprint by choosing our packaging wisely. That means no hangtags or swift tacks and no conventional plastic. When we do use packaging, we choose 100% compostable alternatives made from the bio-based polymer PBAT and the plant-based polymer PLA.
Compared to products that use non-recycled nylon. Based on Higg MSI 3.2 data at Higg.org. Percentage reductions pertain to the finished material phase.

"We believe in a better life through science and design.
Our clothing is the first ever of its kind, providing superior ability to regulate body temperature and reduce energy consumption, a key driver of climate change.
We’re on a mission to fight for a cleaner planet.”
— Scott Mellin, CEO
What We're Hearing
Be the warmest you’ve ever been this winter.
LifeLabs is on to something big here.
This Apparel Company Wants to Have a Profound
Effect on Your Energy Use.
LifeLabs’ new textiles aim to revolutionize
sustainability for clothing.
Minimal-yet-technically sound apparel that would
introduce a new era of sustainability.
- The standard measurement of how warm a textile keeps you (the higher the CLO, the warmer you are).
- The degree of insulation provided by an article of clothing.
- LifeLabs CLO levels are significantly higher than materials almost 30% heavier.
- A type of electromagnetic radiation produced when atoms absorb and then release energy with a frequency lower than visible light.
- Thermal energy your body is producing all the time.
- The measure of an object's ability to emit infrared energy (heat by radiation).
- A low-emissivity material (like aluminum) acts as a radiant barrier and decreases the amount of infrared radiant heat that escapes.
- A tool for the apparel and footwear industry to assess the environmental impacts of raw materials and the lifecycle impacts of products.
- The industry-leading value chain measurement methodology developed by the Sustainable Apparel Coalition.
- A regular organic or inorganic framework supporting a porous structure.
- A nano-scale cell structure that allows body heat to escape through pores to maximize comfort.
- Perfluorinated chemicals, or a subset of perfluorinated chemicals called perfluorocarbons are traditionally used in textile manufacturing to provide water repellency.
- LLD uses PFC-free water repellent finishes to lower or impact on the environment and human health.
- Large molecules made by bonding (chemically linking) a series of building blocks.
- Polymers are chains of chemically bonded atoms.
- A material that conducts infrared heat away from your skin at a higher, more efficient rate.
- Polyethylene has a low Materials Sustainability Index rating compared to conventional synthetic fibers used in apparel today.
- Measurement of thermal transport.
- A higher Qmax value indicates a faster tranfer of heat from the body to the fabric surface, resulting in a cooling effect.
- A measure of predicting the warm/cool feeling of fabrics.
- The return of light, sound or heat from a surface.
- A reflective fabric or material reflects the body's heat back to itself.
- A type of homeostasis and a means of preserving a stable internal temperature in order to survive.
- Thermoregulation is the maintenance of a relatively constant core body temperature.
- Allowing the passage of a specified form of radiation.
- Honest and open; without secrets or deceit. Transparency in materials means that the textile barrier blocks natural elements (like rain and sunlight) and allows other to pass through (like persperation and body heat.)
