Size Guide

Cooling tech meets elegant design

What does 3°F of more effective continuous cooling mean? Let us count the ways: taking that afternoon run when it’s getting hot outside, traveling sans sweat and odor, or letting the AC take a breather. We finish the seams with low-profile merrow stitches that give full expression to the soft, cooling sensation of the fabric. Made from our proprietary scientific fabric that releases your body heat and feels amazingly cool to the touch, this is our CoolLife tech presented in a modern form, with a neckline elegantly tailored to imply a crossover seam.

Sustainable Packaging

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. 

Earth Friendly Materials

Constructed with 42% recycled materials by fabric weight, with 100% recycled polyester labels and sewing thread.

Chemical Impact

63% reduced chemical impact

Fossil Fuel Depletion

58% less fossil fuel depletion

Water Use

28% less water usage

Water Pollution

51% less water pollution

Global Warming Potential

61% fewer CO2 emissions


Compared to products that use conventional nylon. Based on Higg MSI 3.3 data at Higg.org. Percentage reductions pertain to the finished material phase.

CLO Rating

  1. The standard measurement of how warm a textile keeps you (the higher the CLO, the warmer you are).
  2. The degree of insulation provided by an article of clothing. 
  3. LifeLabs CLO levels are significantly higher than materials almost 30% heavier. 

Infrared Radiation

  1. A type of electromagnetic radiation produced when atoms absorb and then release energy with a frequency lower
than visible light.
  2. Thermal energy your body is producing all the time. 


  1. The measure of an object's ability to emit infrared energy (heat by radiation).
  2. A low-emissivity material (like aluminum) acts as a radiant barrier and decreases 
the amount of infrared radiant heat
 that escapes. 

Higg Index

  1. A tool for the apparel and footwear industry to assess the environmental impacts of raw materials and the lifecycle impacts of products.
  2. The industry-leading value chain measurement methodology developed by the Sustainable Apparel Coalition.


  1. A regular organic or inorganic framework supporting a porous structure.
  2. A nano-scale cell structure that allows body heat to escape through pores to maximize comfort.


  1. Perfluorinated chemicals, or a subset of perfluorinated chemicals called perfluorocarbons are traditionally used in textile manufacturing to provide water repellency.
  2. LLD uses PFC-free water repellent finishes to lower or impact on the environment and human health.


  1. Large molecules made by bonding (chemically linking) a series of building blocks.
  2. Polymers are chains of chemically bonded atoms.


  1. A material that conducts infrared heat away from your skin at a higher, more efficient rate.
  2. Polyethylene has a low Materials Sustainability Index rating compared to conventional synthetic fibers used in apparel today.

QMax Index

  1. Measurement of thermal transport.
  2. A higher Qmax value indicates a faster tranfer of heat from the body to the fabric surface, resulting in a cooling effect.
  3. A measure of predicting the warm/cool feeling of fabrics.  


  1. The return of light, sound or heat from a surface.
  2. A reflective fabric or material reflects the body's heat back to itself.


  1. A type of homeostasis and a means of preserving a stable internal temperature in order to survive.
  2. Thermoregulation is the maintenance of a relatively constant core body temperature.


  1. Allowing the passage of a specified form of radiation.
  2. 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.)
