In 2025, serious outdoor athletes are rethinking their base layer systems—and alpaca is increasingly becoming the material of choice. Once considered a niche fiber, alpaca has now entered the mainstream of high-performance outdoor clothing, thanks to its remarkable thermal properties, comfort, and sustainability.
But are alpaca baselayers worth it, or is this just another gear trend? To answer this question, we examined expert reviews, product tests, and athlete testimonials to deliver a comprehensive outdoor baselayers review. Here’s what the data—and the trail—are telling us.
The Rise of Alpaca Baselayers in 2025
Over the past decade, merino wool dominated the base layer scene. However, in recent years, alpaca has emerged as a serious contender, particularly in performance baselayers for cold weather. In 2025, brands like ANDINA OUTDOORS is pushing innovation forward with base layers engineered for extreme conditions, blending tradition with cutting-edge textile technology.
This shift isn’t arbitrary. Professional mountaineers, backcountry skiers, ultra runners, and guides are turning to alpaca for both performance and sustainability. As one Patagonian trekking guide put it: “Alpaca base layers are the best-kept secret in the gear world—until now.”
Alpaca Base Layer Advantages
Alpaca fiber offers a unique combination of qualities that make it highly effective for demanding outdoor environments. Below are the primary alpaca base layer advantages that have positioned it as one of the best base layers for outdoor pros:
1. Thermal Insulation and Breathability
Alpaca fibers have microscopic air pockets that act as natural thermal insulators, trapping body heat without adding weight. At the same time, alpaca is highly breathable, regulating temperature effectively even during periods of high exertion.
2. Moisture Management
Unlike merino wool, which can absorb up to 30% of its weight in moisture, alpaca fibers are hydrophobic. This means they wick moisture away from the skin without becoming heavy or clammy—a critical factor in performance baselayers for cold weather.
3. Odor Resistance
Outdoor pros frequently cite odor resistance as one of the most practical benefits of alpaca. Its naturally low lanolin content and moisture resistance prevent the growth of odor-causing bacteria. For multi-day alpine missions or thru-hikes, this is a game changer.
4. Comfort and Skin Sensitivity
Alpaca is softer than merino, with a smoother fiber structure that reduces itchiness and friction. Athletes with sensitive skin report fewer issues with chafing or irritation, even under heavy packs or tight gear systems.
5. Sustainability
Alpaca is a renewable, biodegradable, and low-impact fiber. Unlike synthetic base layers derived from petroleum, alpaca garments support ethical farming and land stewardship. As more athletes seek sustainable baselayers for athletes, alpaca offers a responsible alternative without compromising performance.
Pros and Cons of Alpaca Baselayers
For a fair evaluation, it’s essential to weigh the full spectrum of benefits and trade-offs associated with alpaca base layers. Here’s a detailed breakdown:
Pros:
- Superior warmth-to-weight ratio
- High breathability and moisture-wicking properties
- Naturally odor-resistant, ideal for multi-day use
- Soft texture, suitable for sensitive skin
- Environmentally sustainable and biodegradable
Cons:
- Generally more expensive than merino or synthetic alternatives
- Less available in mainstream outdoor retail stores
- Requires delicate care—ideally hand-washing or gentle machine cycles
These considerations are important when evaluating if alpaca is the right fit for your activity, climate, and gear setup. However, for those venturing into alpine zones, high-altitude environments, or long expeditions, the performance advantages often justify the cost.

Expert Opinions on Alpaca Baselayers
We reached out to several athletes and outdoor professionals who have adopted alpaca base layers as part of their regular kit. Here’s what they had to say:
- “I used alpaca for the first time on an ice-climbing trip in the Canadian Rockies. The breathability was unmatched, even under three layers.”— Luca D., Mountain Guide
- “After switching to alpaca, I stopped carrying backup base layers on winter hikes. I trust it to perform from dawn to dusk.”— Naomi F., Trail Runner and Outdoor Educator“I’ve been through hundreds of gear pieces. Alpaca is in my top five game changers of the last decade.”— Miguel R., Expedition Photographer
These expert opinions on alpaca baselayers reinforce a consistent pattern: alpaca performs reliably under demanding, high-stakes conditions.
Are Alpaca Baselayers Worth It?
