What does Lasclay mean?
Lasclay is an invented name derived from the French word Asclepiade, which literally means Milkweed. Since our company is entirely dedicated to the preservation of monarch butterlies and their host plants (milkweeds), it was a simple and clean fit. We wanted our brand name to be about "L'Asclepiade" without sounding corny or simply too obvious. So, we decided to take the first two syllables "L'AS-CLÉ" and make sure everybody could pronounce it right by calling ourselves "LAS-CLAY". We love our French-Canadian culture and heritage, and so we thought Lasclay was the perfect bridge between our origins and our passion for milkweed.
Does harvesting milkweed harms monarch butterflies, since they depend on milkweed for reproduction?
No, it's actually the opposite! The white silky fibers that are harvested from the mature plant is of no interest to monarch butterflies, and is only available long after the monarchs have left Canada towards Mexico. As the days get shorter and colder in the fall, milkweed plants start shedding all the leaves that monarchs used to feed on, and concentrate their remaining energy to produce seed pods. Monarch caterpillars feed on young milkweed leaves and the adult butterflies feed on flower nectar from spring to late summer. When these resources are no longer available, monarchs are triggered to migrate back to Mexico, leaving behind them seed pods full of the silky fibers we use as insulation in our products. There is reason to believe that large-scale milkweed farming saved monarchs from near extinction in 2013 and helped them bounce back to population levels unseen since the late 1980s.

Where are your products made?
Everything happens in Quebec, whether we're talking about milkweed harvesting, product design, manufacturing and distribution. Our philosophy is to produce as locally as possible to reduce the environmental impact of the clothing industry. This project is our humble contribution towards this goal.
What makes milkweed a better insulation?
For winter clothing and accessories, two types of insulators are mainly used: Plastic fibers/membranes, such as Thinsulate, are made from petroleum exploitation (polyethylene and polypropylene). Animal fibers, such as fur or goose down. Each of these options has many environmental, social, and ethical disadvantages. There is no need to go into detail about the harmful impacts of oil exploitation and the moral stakes posed by animal exploitation for fur and down. Milkweed, on the other hand, provides a natural fiber derived from the indigenous plant itself. Milkweed is perfectly adapted to the climate of North America and generally does not require pesticides or chemical fertilizers. While the production of the main popular insulators harms the environment, the exploitation of milkweed provides benefits to its ecosystem, including providing food and nesting grounds for the precious monarch butterfly, an endangered species. It is also worth noting that it's very rare to find a win-win situation where the production and exploitation of raw material also benefits the environment To learn more, check out our information page on milkweed.
