Unlike any other brand, we are using a 100% lyocell fabric for our jeans. It may be more expensive (and harder to work with) than cotton, but you’re worth it. Not only does this single fiber construction make again&again jeans fully circular, it makes a wildly comfortable jean.

100% LYOCELL FABRIC
WHY ARE LYOCELL DENIM JEANS BETTER FOR YOU?
Lyocell, as we describe in more detail in our FAQs, is a semi-natural fiber as it is cellulose based like cotton but not found in nature. Made from Eucalyptus trees, this fiber provides many benefits over cotton.
While constructed from the same cellulose building blocks that comprise cotton and viscose, lyocell has special features due to its unique dry jet-wet spinning manufacturing process. At the micro meter level, lyocell fibers have a smoother surface than other cellulose based fibers, round cross-sections, and a dense fibrillar structure.
What this means for you, is lyocell fabric is extremely soft to the touch. The smooth surface of the individual fibers provides a softness you wouldn’t expect in jeans. There is a reason fancy bed sheets are made of lyocell. It is the perfect material to sleep in. So why not wear that same material all day?
Lightweight and breathable
The unique microscopic composition of lyocell fibers further contributes to its advanced performance as a fabric. Lyocell is comprised of nanofibrils, literally very, very small, hydrophilic fibers. This means lyocell is less dense than other fabrics and has a unique moisture absorption ability. It is more breathable and lighter than cotton-based fabrics.
So why does this matter for your jeans? Because we have all experienced that moment of sweaty thighs after running to catch the train or wearing jeans on a slightly too warm summer night. We can’t promise you will never sweat again, but we can promise our jeans will keep you cooler and dryer. You will stop sweating and feel comfortable faster, or maybe not start sweating at all. It’s what lightweight and breathable can do.
The additional benefits that lyocell’s moisture absorption provides deserves its own section. Because lyocell absorbs moisture and wicks it away better than cotton, it is a better fabric for people with sensitive skin that may be aggravated by moisture.
Less moisture on your skin and in your jeans also helps protect from odor. More moisture wicking means sweat stays in the garments for less time, so the jeans will stink less. Besides keeping you smelling fresh, this is great for the environment. According to a study (pdf) from Levi’s, consumer care accounts for 23% of the water usage for the entire lifecycle of a jean. Washing jeans less is great for the environment. And that is easier to do when they smell better for longer.
For the last piece of science-based benefits, the crystalline structure of lyocell fibers provide greater tensile strength when dry or wet. The air gap in the manufacturing process allows lyocell to crystallize more than other fibers, increasing its dry and wet tenacity. In other words, lyocell is more durable than cotton or viscose fibers when dry or wet.
These mechanical properties keep lyocell specifically resistant to wrinkles and slow the formation of unwanted holes in jeans. If you are like us, you are tired of blown out crotches, frayed legs, and ripped pockets. Lyocell fabric helps prevent those issues with its increased durability compared to cotton.
WHY ARE LYOCELL JEANS BETTER FOR THE PLANET?
From the start, lyocell denim, and specifically, TENCEL lyocell denim, is far more sustainable than denim made from cotton, organic cotton, or blends of those fabrics. This is due to both the raw material source of cellulose for lyocell versus cotton and the clean production process of lyocell.
Our lyocell fiber is made by Lenzing under the brand TENCEL. The process is illustrated to the left. Lenzing sources sustainably grown eucalyptus trees to grind into cellulose pulp. This is already better than cotton sourcing for a few reasons:
- Eucalyptus trees require just 5% of the water and 20% of the land that cotton requires to grow
- Eucalyptus trees do not require the toxic pesticides used in conventional cotton agriculture
lyocell fabric is extremely soft to the touch. The smooth surface of the individual fibers provides a softness you wouldn’t expect in jeans.
And you may be thinking organic cotton solves these problems. Unfortunately, the answer may not be so simple. While organic cotton does avoid the use of pesticides and chemicals, one study showed it requires twice as much water as conventional cotton to grow the amount necessary for a pair of jeans. This is because organic cotton, by definition, has not been genetically modified, so its yield is lower than conventional cotton.
Lenzing then uses a circular process to convert the cellulose pulp into lyocell fiber using a non-toxic, natural organic solvent NMMO (N-methylmorpholine-N-oxide). Even better, 99.5% of the organic solvent is recovered to be used again (and again) for future fiber production.
Through our supply chain partners and your help, again&again will make this process even more sustainable and circular. As our company grows and sells more jeans, we will supplement eucalyptus trees as the source for cellulose pulp with your old jeans, creating truly circular jeans made from 100% old jeans. Your jeans will be re-born and given new life, again and again.
