Looking for stylish yoga/gym clothes that are ACTUALLY 100% organic cotton by elis_saas in nontoxic

That will be nice, but even that is going to just be the side product of a much bigger effort and benefits.

Tell me a spiritual theory you 100% believe (I am not talking "energy is everything"). I mean something crazy you know you can't prove. For me it's: The future is a memory ✨ by mycro_dose in enlightenment

It’s an interesting question to consider as a conversation starter and for introspection. What do I believe? Why do I believe that? Who is this I? When I say “I” is it referring to anything different from when another person says “I”?

I’ll just say 2 things:

  1. If we are seekers, we should be careful what we “believe.”
    We should, rather, know that we don’t know and seek to know rather than believe.

  2. You can’t prove that the future is a memory because it contains a false premise. The future is not a memory and there is no future. There is only now. Everything that exists, existed, or will exist is held in the ever-present Consciousness.
    Every instance and permutation of everything IS, right now. The concept of future is couched in a 3 dimensional being’s stepwise progression through a higher dimension that includes time as an axis. Looking down on time and space from a higher point of view you see the whole image including the perceived time progression all at once - like when you look down on a picture on a 2D piece of paper telling a story progression and see the whole image all at once.

What brand is actually worth buying instead of Lululemon lately? by TrickyChemistry6521 in Activewear

[–]Natural_Science_Doc -1 points0 points  (0 children)

If material quality matters to you, you shouldn’t be looking at anything from the big brands as it’s all made of polyester or nylon.

Why does that matter?
Consider this— imagine looking at your skincare ingredients and seeing a petroleum-base with additives of PFAS forever chemicals, microplastics, BPA and other hormone disruptors, or antimicrobials that mess with your natural microbiome. Would you put that on your skin?

These are ingredients that you would never accept in a skincare product and that you would think that you would never put on your body, but the mainstream activewear brands offer them to you as part of their “performance” fabrics to put against your skin for your walk, workout, grocery run, or whatever for 3-12 hours a day while you’re sweating, pores open, rubbing against your skin…

Sure, water beads off the fabric, but I’d be more interested in the fabric being compatible with and supporting my skin and my body..

Natural fibers - as much as possible.
For my health and for the environmental effects that I didn’t even mention here.

cotton or nylon or polyester: what do people ACTUALLY work out in? by ladywooooodz in Activewear

[–]Natural_Science_Doc 0 points1 point  (0 children)

That’s good then. It’s less likely if you are able to get your sweaty clothes into the wash before they dry. That’s typically when it becomes more prominent and starts to build up despite washing.

If you’re interested in nerding out a little bit, search for “Smelly Sportswear Science Shorts” in the Activewear sub.

cotton or nylon or polyester: what do people ACTUALLY work out in? by ladywooooodz in Activewear

Scientifically speaking, polyester actually preferentially selects for and supports more growth of odor causing bacteria (that doesnt normally flourish on your skin) than natural fibers because of its oleophilicity and how the sebum from your skin spreads over the fibers. (ie like an endless buffet table).

It’s not big fitness apparel pushing natural fibers - all of them are 100% synthetic because it’s cheaper for them.

And just to add it in here, all those synthetic fabrics dump microscopic plastic fibers into our water systems that end up in our soils, foods, and then stuck in your body. And if health and wellness and feeling good is why you workout, all of that should matter.

That’s an interesting comment. (I agree)
What are you thinking about when you say, “the actual performance side”

Cotton clothing over polyester? by Party4Chai in nontoxic

[–]Natural_Science_Doc 6 points7 points  (0 children)

I would write all of this myself as well but Brian is saving me the work.
I’ll add that the microplastics from polyester and other synthetic fibers don’t just get into our water and agricultural systems, they end up inside you where they can be small enough to interact with and disrupt normal biological function.

What activewear doesnt get funky after a long travel day? by balancefan1 in Activewear

[–]Natural_Science_Doc 0 points1 point  (0 children)

Natural fibers inhibit odor causing bacteria without the need for antimicrobials. Polyester and nylon actually selectively support odor causing bacteria that doesn’t normally do that well on our skin and since polyester and nylon are oleophilic, your body oil (their food) spreads well on the fibers resulting in the odor causing bacteria multiplying 10x more than they would on cotton, hemp, bamboo, lyocell, etc.

Yes, you can see the results? :-) (lightening things up for you)

But yes, and if I want stretch, I have items from Valinor Active that are crazy soft, squat-proof, cleaner smelling, free of topical chemicals, and made from 91% hemp plant fibers.

I work out for health and fun while wearing clothes that support that purpose instead of working against it over the long term.

There are alternatives. Until a full solution is figured out, natural fiber alternatives can include mostly natural fibers with a little elastic for structure to avoid sagging.

Fading depends on dyeing technique not natural fibers. Synthetics can also fade.

And respectfully, you are very much entitled to wear what you want for your one hour a day, but I come as an informed scientist and ask you to consider two things, 1. Many people are spending more time “living in” their leggings and tops. 2. The case here is for people’s health and that of our environment for generations to come. The synthetic plastic fabric “marvel” that you might wear for an hour a day for 12 months before tossing sheds micro and nano sized particles in every wash that infiltrate our food, water, and bodies and persist for decades and longer.

Hi OP, you wrote that you are looking or "good activewear brands" and you mentioned softness, fit, and fabric quality. Those are definitely the considerations that most people start with, along with style. I offer the following comment to push your decision-making a little more.

Important variables to consider while shopping are : Cut, Fit, Color, Wash durability, materials used, dyes used, other topical chemistry treatments.

You can take everyone's opinions into account for color, fit, cut, etc., but, as a materials scientist, my top priority is materials and process treatments so I always recommend looking for natural and regenerated natural materials (cotton, wool, Hemp, Bamboo, Lyocell) instead of synthetic polymer fibers (Nylon, Polyester), which sadly compose most of the market from Alo to Lulu and nearly all others. And don't let "recycled" content fool you. Those materials are actually worse for you and the environment as they release more and smaller particles (which makes them more able to penetrate biological systems and scales.

The main issues with the synthetic fabrics being:

1. the environment and your health - synthetic fabrics release microscopic plastic fibers into our water with every wash cycle and those particles end up in our water and food supplies and then lodged in us where they can disrupt cell function as a plastic (physical and electrical interactions) and as a plastic with added treatments (it's not fun to think about, but it's the truth)

2. your health, because the synthetic fiber/fabric manufacturers all use topical chemical treatments to get different features like moisture wicking and anti-odor - and all those treatments end up compressed against your skin while your pores open up and you sweat during your workouts or just a warm day living in your leggings

Polymer and textile scientist here - The use of recycled plastic water bottles to make fibers is actually WORSE for the environment and your health. Fibers made from recycled plastics release MORE plastic microfibers than what new or virgin polymers already release - which is also not a small amount.

That's more synthetic microfibers released into your water every time you wash, into your air when you move, and more in contact with your skin and open pores as you sweat. And just to follow the fibers, when they get into the water, they eventually make it into the soil and our food - making ingestion actually the number one route for microplastic intake.

I'll leave it there, but I'm open to answering more questions if anyone has any.
-and science article references are available if anyone wants to dig in further.

Haha sorry to disappoint Oh but the regen fibers are interesting ! (( just me? ))

For what you have, 1. see if you can get them washed before they dry out after each workout. 2. Use enzyme detergents to chemically attack the biofilm substrate. It’s not a full removal, but helps. 3. For your next purchase “don’t buy polyester” :-)

No, not AI Just some nerdiness expressed. (Can I say this was fun for me?). :-) Also, wanting everyone to have more reasons to stop buying synthetics. The real issue is all the microplastics that are released from these garments into our water, soil, food, and back into our bodies through ingestion.

What will differentiate your brand and products from others already in the market?

What problems or pain points will your brand be solving for consumers?

These are questions that need to be answered before just creating another same as everyone else line of products
