There is no ‘Best‘ Outlast Fabric. It Depends on Your Product and Your Standards.
If you're sourcing temperature-regulating fabric, you‘ve likely encountered Outlast. It’s the PCM-based technology that promises to absorb, store, and release heat. But as a quality and brand compliance manager who reviews hundreds of technical fabric specifications annually, let me tell you: there is no universal “best” Outlast fabric. The choice depends on where the fabric is going, how it‘s being used, and—critically—what level of quality your brand demands.
Think of it like this: You wouldn't use the same canvas for a tent, a tote bag, and a pair of sneakers. Same logic applies here. The “best” Outlast fabric for an outdoor jacket is not the same as for a pillowcase. Period.
Scenario A: The ‘All-Day Performance‘ Apparel
This is the most common application you'll see—Outlast for activewear, base layers, or outerwear. The goal is thermal equilibrium for the wearer during high activity or changing conditions.
What I look for as a quality inspector: In our Q1 2024 quality audit, I rejected 18% of first deliveries from a new vendor claiming Outlast certification. The issue wasn‘t the PCM itself. It was the coating integrity. The PCM microcapsules must be durably integrated into the fiber or coating, not just “dusted” on. If the coating flakes or washes off after 20 cycles, your $150 jacket becomes a $50 piece of standard polyester.
The right call: For apparel, specify Outlast+1.0 or Outlast+2.0 (the more recent generation with improved durability). Demand a wash-test report from the manufacturer showing PCM retention after 50 laundry cycles. I’ve seen a 30% performance drop in lower-cost variants (unfortunately). If your brand promise is “active comfort,” this is a non-negotiable spec. The cost increase for certified, tested fabric might be 15-20%, but the alternative is a warranty disaster.
Real-world anchor: “When I compared our Q1 and Q2 fabric deliveries side-by-side—same target spec, different PCM densities—I finally understood why the certification matters. The cheaper batch looked identical. It failed after 60 wash cycles. The reorder cost us $22,000 in expedited shipping and a two-week production delay.”
Scenario B: The ‘Sleep and Recover‘ Product (Bedding & Home)
Outlast in sheets, pillows, or mattress pads is a different beast. The temperature-regulation need is passive. The user is static for 7-9 hours. The failure mode isn’t washing—it‘s sweat and pressure.
What I look for as a quality inspector: The assumption error I made early in my career? I assumed “same specifications” between an apparel fabric and a bedding fabric meant identical results. Turned out they don't. Bedding Outlast needs a higher PCM concentration per square meter because the user is constantly in contact with the fabric, and the cooling/heating demand is slower and lower than in activewear.
The right call: For bedding, you want Outlast+0.5 (a specific grade for passive regulation) or a custom formulation with a higher PCM loading. But don't overdo it—too much PCM can make the fabric feel stiff or “waxy.” I’ve seen a $50 pillow feel like a dense foam block because the coating was too thick. Test the hand feel (ugh). The sweet spot is a fabric that feels like a standard premium sateen but regulates temperature under a duvet. Price per yard is typically 10–15% more than standard premium bedding fabric.
Real-world anchor: “I ran a blind test with our product team: same pillow design with Outlast bedding-grade fabric vs. a standard premium cotton. 78% identified the Outlast variant as ‘more comfortable for sleeping’ after two nights of use. The cost increase was $1.20 per pillow. On a 50,000-unit run, that’s $60,000 for a measurably better perception.”
Scenario C: The ‘Industrial/Technical‘ Application (Gear, Liners, Covers)
This is the niche. Outlast for safety vests, glove liners, or technical covers for electronics. The requirements are different: flame resistance, abrasion resistance, or durable waterproofing (and yes, canvas can be waterproof with a coating—but the PCM must not be compromised).
What I look for as a quality inspector: The biggest pitfall here is compatibility with lamination. If you‘re bonding Outlast fabric to a waterproof membrane (like for a tent floor or a tactical vest), the lamination process can destroy the PCM microcapsules. The heat and pressure of the lamination press can melt or rupture them.
The right call: Specify Outlast+2.0 (Industrial Grade) and require a lamination compatibility test report from your converter. I rejected a batch of 8,000 units in Q3 2023 because the PCM was rendered inert after lamination. The vendor claimed it was “within industry standard” for the lamination process. We rejected it. They redid it at their cost with a cooler-lamination process. Now every contract includes that spec requirement.
“It's not about being the cheapest. It’s about having a spec you can defend.”
So, Which Outlast Fabric is Right for You?
Here's how to diagnose your scenario:
- What is the end-use? Active apparel (Scenario A) / Bedding (Scenario B) / Technical (Scenario C)
- What is the wash cycle requirement? If >20 cycles, you need Scenario A or B grade. If zippered or rarely washed, Scenario C might work.
- What is your risk tolerance? If your brand is premium, don‘t skip the wash-test or lamination report. The $50 difference in fabric cost per unit is nothing compared to a recall.
- What is your testing budget? For a first-run prototype, use a lower grade. But write a specification that can be upgraded. I learned never to assume a prototype and final production will be the same.
A final note on pricing: As of January 2025, based on quotes from three certified Outlast fabric licensees, you can expect to pay:
- Scenario A fabric: $12–18 per yard (60” width)
- Scenario B fabric: $10–15 per yard
- Scenario C (with lamination compatibility): $18–25 per yard

There is no one-size-fits-all. But if you define your scenario, test your spec, and protect your PCM integrity, you’ll get a product that works. And your customers will notice. Simple.
