If you’ve landed on our site and noticed two long sleeve tops that look almost identical, you’re not alone. Both the Zone Raglan and the Universal Long Sleeve are black, long sleeve, and made from superfine Australian Merino wool. But there’s a reason we carry both — they serve slightly different purposes, and knowing the difference can help you pick the right one for your day-to-day or next adventure.
Let’s break it down.
🧵 Zone Raglan: The Comfort-First Performer
Key details:
- Fabric: 180gsm, 100% Superfine Australian Merino Wool (MicroMerino®)
- Fit: Casual fit
- Construction: Raglan sleeves, flatlock seams (no shoulder seams)
Think of the Zone Raglan as your go-to if you value freedom of movement, comfort, and a slightly looser fit. It’s made from a slightly thicker fabric (180gsm), so it’s a little warmer and sturdier than your ultralight thermals, but still incredibly soft and breathable.
Because it’s all-natural merino with no synthetic blend, it’s ideal for:
- Casual wear
- Day hikes or travel
- Activities where comfort and breathability matter, but you’re not thrashing the garment
Bonus: The raglan sleeve design means no seams sitting on your shoulders — ideal for carrying a backpack without rubbing or chafing.
⚙️ Universal Long Sleeve: The Everyday Performance Layer
Key details:
- Fabric: 160gsm, 83% Merino Wool, 12% Nylon, 5% Elastane
- Fit: Slim/Active fit
- Performance edge: Stretch, shape retention, extra durability
At 160gsm, the Universal Long Sleeve is slightly lighter and engineered for versatility. The added nylon and elastane give it extra durability and stretch, which makes it perfect for high-movement activities, multi-day wear, and anything that blends performance and lifestyle.
Choose the Universal if you want something that:
- Can handle workouts, runs, and travel
- Has more give and shape recovery
- Moves with you and bounces back after a long day
It’s the kind of top that works just as well for airport travel as it does for hiking or a quick gym session.
🧶 TL;DR – Which One’s for You?
