Patagonia R1 vs. Arc'teryx Delta: Which one is better? [2026]

The Patagonia R1 and Arc'teryx Delta are two of the most respected fleece jackets in the outdoor industry, but they cater to slightly different users. The main difference is their focus: Patagonia's R1 prioritizes versatile performance, value, and industry-leading sustainability, while the Arc'teryx Delta is engineered for ultimate technical performance, durability, and a minimalist design at a premium price.

Here's everything you need to know to decide which of these iconic midlayers is the right choice for your adventures.

Patagonia R1 Fleece

The Patagonia R1 is a legendary fleece known for its exceptional versatility and incredible warmth-to-weight ratio. As a brand committed to environmental responsibility, the R1 series is made primarily from recycled materials, making it a favorite among eco-conscious hikers, climbers, and skiers who need a reliable midlayer that can handle a wide range of conditions without a hefty price tag.

• What it is: A highly breathable, high-performance fleece midlayer known for its signature grid-style interior fabric that efficiently traps warmth while wicking moisture.
• Key features: DWR (durable water repellent) finish on some models, odor control properties, flatlock seams to reduce chafing, and a design focusing on versatility across many activities.
• Price: $150–$200, depending on the model (e.g., zip-neck vs. full-zip).
• Materials/Construction: The R1 uses Patagonia’s proprietary Regenerative Fleece, which is made almost entirely from recycled polyester, and its construction is Fair Trade Certified™.
• Sizing/Fit: Tends to run true to size with a comfortable, slightly relaxed fit that is ideal for layering over a base layer without feeling restrictive.
• Pros: Excellent value for the performance, outstanding eco-friendly and ethical credentials, highly versatile for various activities, comfortable for all-day wear.
• Cons: The relaxed fit is less suited for highly technical layering under a trim shell, and while durable, it may not withstand repeated extreme abrasion as well as the more expensive Delta.

This fleece works best for the outdoor enthusiast who needs a reliable, do-it-all midlayer for everything from weekend hikes to backcountry skiing and values sustainability as much as performance.

Patagonia R1 vs. Arc'teryx Delta Comparison

Price & Value

There's a clear price difference between the two jackets. The Patagonia R1 generally costs between $150 and $200, representing fantastic value. You get a high-performance, eco-friendly fleece that can handle almost any adventure. Sales events also make it even more accessible.

The Arc'teryx Delta sits at a higher price point of $180 to $220. While more expensive, that cost gets you industry-leading technical materials, meticulous craftsmanship, and long-term durability that demanding users will appreciate. For serious athletes, the performance benefits justify the extra cost.

Materials & Durability

Patagonia's R1 fleece is made with recycled polyester in a grid pattern. It's soft, comfortable, and remarkably durable for its price. It holds up well to normal wear and an active outdoor lifestyle. It does its job of keeping you warm and dry effectively and reliably.

Arc'teryx leverages Polartec® Power Dry® fabric, which has an edge in extreme conditions. It wicks moisture away from the skin slightly faster and has a reputation for incredible long-term durability, resisting pilling and stretching even after years of demanding use. If your jacket will be constantly scraped against rock or worn under a heavy pack, the Delta’s construction provides peace of mind.

Fit & Aesthetic

The aesthetic difference is immediately noticeable. The Patagonia R1 has a more classic, slightly relaxed outdoor fit. It's designed to be comfortable and versatile, easily worn as a standalone jacket for a fall hike or layered for skiing. The look is accessible and functional.

In contrast, the Arc'teryx Delta has a sleek, minimalist, and highly athletic fit. It's cut trim to sit close to the body, which reduces bulk, enhances its moisture-wicking efficiency, and makes it perfect for layering under a harness or a slim-fitting shell. Its technical appearance feels at home on a mountain face or in a modern urban setting.

Sustainability & Ethics

This is where Patagonia clearly leads. The brand has built its identity on environmental and ethical responsibility. The R1 is made with recycled materials and is Fair Trade Certified™, meaning the people who made it earned a premium for their labor. Patagonia’s Worn Wear program also promotes repair and reuse, extending the life of your gear.

Arc'teryx is committed to sustainability and responsible manufacturing as well, but it is not the central pillar of its brand identity in the same way. While they are improving their use of recycled materials and responsible sourcing, Patagonia currently sets the standard in the outdoor apparel industry.
