Quick Answer
Most Patagonia clothing runs true to size, especially fleece, jackets, and everyday outdoor wear.
However:
- Technical shells may feel slightly roomy for layering.
- Base layers and slim-fit items may feel more fitted than expected.

1. How Patagonia Sizing Typically Fits
Based on OEM pattern-making and fit-testing feedback:
✔ True to Size
Most jackets, fleece, parkas, and vests follow standard US sizing.
✔ Roomy in Technical Shells
Designed for layering, so the chest and shoulders may feel looser.
✔ Slim in Base Layers
Their Capilene series tends to fit closer to the body for performance.
✔ Consistent Across Seasons
Patagonia maintains stable grading rules, so sizing rarely changes year to year.
Summary:
Patagonia = reliable, consistent, and predictable sizing.
2. Patagonia vs Other Outdoor Brands
| Brand | Fit Feel | Notes |
|---|---|---|
| Patagonia | True to size | Reliable, outdoor-focused fits |
| The North Face | Slightly large | More relaxed in jackets |
| Arc’teryx | Slim / tailored | Technical and athletic fit |
Takeaway:
Patagonia sits right in the middle—neither too slim nor too bulky.
3. Which Patagonia Items Run Big or Small?
| Category | Fit | Notes |
|---|---|---|
| Fleece (Better Sweater, R1) | True to size | Comfortable and consistent |
| Down Jackets | True to size | Designed for layering without being oversized |
| Rain Jackets (Torrentshell) | Slightly large | Extra room for mid-layers |
| Technical Shells | Slightly large | Performance-focused mobility |
| Base Layers | Slightly small | Slim fit for moisture management |
OEM Insight:
Technical outerwear often uses layering allowance in chest + shoulders.
4. How to Choose the Right Size
Choose true to size if:
- You’re buying fleece, down jackets, or casual outerwear
- You want a standard everyday fit
- You wear normal mid-weight layers
Size down if:
- You prefer a very fitted look in rain jackets or shells
Size up if:
- You’re buying base layers and prefer extra room
- You have broader shoulders or athletic build
