TL;DR: Pact makes inexpensive organic cotton basics. Wayve makes performance training gear and elevated basics. The bigger difference is in the fabric: Pact's stretch pieces blend elastane through the body fabric — their leggings run 89–95% organic cotton with 5–11% elastane — while every Wayve body fabric is 100% natural fiber.
The five differences
1. Blended fabric vs 100% natural
The difference that matters most, and the one the marketing doesn't make obvious.
Pact describes its products as "made with organic cotton," and for tees and underwear that's largely accurate. But across the stretch categories, elastane is blended through the body fabric — their leggings run from 89% organic cotton / 11% elastane to 95% / 5%. That's synthetic fiber in every square inch touching you, and it sheds microplastics in the wash.
Wayve doesn't blend. The Quad Short shell is 100% organic cotton and the liner is 100% merino wool. No elastane in either fabric. Stretch comes from the merino and the knit construction rather than from added plastic.
If you want a natural fiber garment with no synthetic blended in, that's a shorter list than the roundups suggest.
2. Cheap basics vs performance and elevated basics
Pact is built to a price — roughly $20–$138 — and it does that well. Tees, underwear, socks, loungewear. It's the value option in certified organic cotton and that's a real position.
Wayve is a different job: training gear plus elevated everyday pieces. The Quad Short at $90 has a merino liner, zip side pockets, a 6" liner under a 4" shell, and cotton tags and care labels instead of printed polyester. The Only Tee at $45 is a 240GSM midweight, not a lightweight throwaway.
Different price, different garment, different lifespan.
3. Fabric weight
Pact doesn't publish fabric weight. Its tees are lightweight everyday jersey, priced accordingly.
Wayve publishes it for everything — 240GSM on the Only Tee, 260GSM on the Classic Short, 290GSM shell and 165GSM liner on the Quad Short.
Heavier isn't automatically better, but it's the difference between a tee that lasts two seasons and one that lasts five — and publishing the number lets you decide before you buy.
4. Merino wool
Pact is a cotton-only brand. Cotton holds moisture, which is fine in a t-shirt and a problem in a training short.
Wayve pairs organic cotton with merino wool. In the Quad Short, a 165GSM merino liner handles odor resistance, thermoregulation and natural stretch — the jobs a chemical finish or an elastane blend would otherwise do. That's what makes natural fiber activewear work at all.
5. Certification
Both hold real certification, and Pact holds Fair Trade where Wayve doesn't.
Pact: GOTS-certified organic cotton and Fair Trade Certified factories.
Wayve: 100% GOTS-certified organic cotton, OEKO-TEX Standard 100 low-impact dyes, RWS-certified merino on the Flow Set.

The verdict
Buy Pact if you want inexpensive organic cotton basics and you're not bothered by elastane blended into the stretch pieces. It's the best value in the category and Fair Trade certification is a genuine credential.
Buy Wayve if you want 100% natural fiber with nothing blended in, and gear built for training rather than lounging — published fabric weights, a merino liner doing real work, and construction that holds up when you move.
Pact is where you buy six cheap tees. Wayve is where you buy the short you train in four times a week and the tee you still like in three years.

FAQ
Is Pact organic cotton actually certified?
Yes. Pact uses GOTS-certified organic cotton and works with Fair Trade Certified factories. It's one of the more credible organic cotton brands at its price.
Which is better quality, Wayve or Pact?
Different targets. Wayve's fabrics are heavier and 100% natural — 240GSM on the Only Tee, published so you can check. Pact is built to a lower price and does that well.
Does Pact use synthetic fabric?
In its stretch categories, yes. Pact leggings blend elastane through the body fabric at 5–11% depending on the style. Its plain cotton tees and underwear are largely cotton. Wayve blends nothing into any body fabric.
Does Pact make activewear?
Some cotton athletic basics, but not engineered training apparel. There's no merino, no liner construction and no published fabric weight.
Is Wayve Fair Trade certified?
No. Pact is. Wayve holds GOTS, OEKO-TEX Standard 100 and RWS.
Which is better value?
Pact per item. Wayve per wear, if you're buying something you'll train in regularly — heavier fabric and merino outlast lightweight cotton by years.
