Arms Of Andes

About Arms of Andes

Price Range: $$-$$$

Arms of Andes was founded five years ago by siblings Meli and Rensso Hinostroza in Peru. As Californians of Peruvian descent, they decided to “bridge the gap between the heritage of [their] ancestors and the modern world”.

And they make that a reality in their line of sustainable activewear made from Alpaca wool!

You can find super soft men’s base layers, mid layers, shirts, bottom layers, underwear, socks and more.

Arms of Andes’s Ethical & Sustainability Practices

Materials:

Arms of Andes’ flagship material is their 100% alpaca wool fabric, one of the most sustainable fabrics and ethical wool options available.

Alpaca wool is 100% compostable and Arms of Andes sources from Alpaca herders where alpacas are raised in small, free-roaming herds in the Peruvian Andes.

The wool is OEKO-TEX 100 certified and naturally dyed.

Other materials used are cotton stitching and zippers made of a metal and cotton/synthetic mix.

Supply chain & labor practices:

Arms of Andes has a solid understanding of its suppliers and factories, all of which are based in Peru.

First, the wool is sourced from Alpaca herder co-ops in exchange for living wages.

Kotn

About Kotn

Price Range: $-$$$

Kotn’s answer to the rampant ethical abuses within the fashion industry?

Ethically sourced Egyptian cotton.

And this Certified B Corp uses just that in its affordable men’s clothing, which includes flannel shirts, button-downs, sweatshirts, sweatpants, chinos, long johns, denim, work pants, and sustainable socks.

Kotn’s Ethical & Sustainability Practices

Materials:

Most of the world’s cotton usage consists of short-fiber cotton, while Pima and Egyptian cotton are long-fiber crops making more durable fabric of higher thread count (meaning it’s softer, too).

The premium cotton only comprises 10% of garments.

Kotn goes beyond this and uses Giza “white gold” cotton, the finest of all Egyptian cotton available.

While Kotn garments are all 100% Giza cotton, not all of it is organically grown yet but they are helping farmers transition to organic practices so that it eventually will be. Their first organic line will be launching soon.

Supply chain & labor practices:

Kotn is a direct trade company which operates by purchasing cotton directly from family-run farms at set prices. This way farmers aren’t impacted by the market value of cotton as it fluctuates.

All farms and factories are subject to regular third-party audits, which include interviews with the workers to ensure they are happy.

Green business practices:

Giza cotton can only be grown in the Nile Delta region south of Alexandria, so all entities are centralized within a 100km radius.

Giza cotton also has to be handpicked, as machines can stress and even damage its long, fine strands. Happy coincidence, though, as there are fewer machine emissions and more jobs created.

Inclusivity:

Kotn sizes tops XS-XXL and pants from 29/30 to 38/32.
