Overview
The Patagonia Micro D Fleece Jacket is a minimalist midlayer engineered for everyday warmth, light layering, and travel-friendly versatility. Weighing just under 200g, it’s one of the lightest full-zip fleece jackets on the market. Its soft microdenier construction makes it ideal as a light insulator or standalone layer for spring hikes, cool evenings, and low-output activities.
But while it’s whisper-thin and ultra-packable, how does it stack up against pricier performance-oriented fleece options like the R1® Air or Arc’teryx Delta series?

Fabric & Performance
The Micro D is made from ultra-soft, 4.7 oz recycled polyester microfleece, brushed on both sides for warmth and skin comfort. It provides:
- Excellent warmth-to-weight ratio for low-output activities
- Fast drying performance after light rain or sweat
- Highly breathable, though not wind-resistant
- A touch of stretch despite being non-elasticised
This is not a technical fleece for trail running or alpinism. It excels as a camp layer, travel shell, or cozy insulation under a windbreaker.
Fit & Comfort
- Cut: Standard “regular fit”—not baggy, not slim
- Length: Sits just below the waist; easy to tuck under hip belts or harnesses
- Mobility: Excellent articulation at elbows and shoulders
- Pockets: Two zippered hand warmer pockets lined with fleece
The low-profile collar is soft and non-chafing, and the sleeves are long enough to protect wrists when layering under rain shells. It feels more like your favourite pyjama top than a technical fleece—and that’s a compliment.
Sustainability
Patagonia’s Micro D is part of its NetPlus® and recycled content range:
- 100% recycled polyester from post-consumer plastic bottles
- Made in Fair Trade Certified™ factories
- bluesign®-approved materials
For shoppers prioritising eco-conscious apparel, this is a strong candidate that doesn’t cut corners on comfort to meet sustainability goals.
Versatility & Use Case
| Activity | Performance |
|---|---|
| Everyday layering | ⭐⭐⭐⭐⭐ |
| Chilly morning bike commutes | ⭐⭐⭐⭐☆ |
| Travel & ultralight packing | ⭐⭐⭐⭐⭐ |
| Hiking in shoulder season | ⭐⭐⭐⭐☆ |
| Active alpine use | ⭐⭐☆☆☆ |
It’s not for high-intensity pursuits or stormy weather—but as a layer for casual movement, recovery, or shoulder-season wandering, the Micro D is sublime. Stash it in your pannier or daypack, and it feels like carrying a warm hug that weighs less than a banana.
Compared to Patagonia R1® Air & Nano Puff
| Feature | Micro D® | R1® Air | Nano Puff® |
|---|---|---|---|
| Warmth | Light | Moderate+ | Moderate |
| Weight | ~187g | ~290g | ~320g |
| Weather Resistance | None | Minimal (air-permeable) | Wind/water-resistant |
| Best Use | Everyday, travel | Active layering | Cold-weather outer layer |
| RRP (GBP) | £79 | £110 | £190 |
If you need warmth during movement, the R1® Air is more breathable and suitable. If you’re layering for winter, the Nano Puff adds real insulation. But for light-duty wear from March to October, the Micro D still reigns in comfort and simplicity.

Final Verdict
The Patagonia Men’s Micro D® Jacket is a comfort-focused fleece for people who want lightweight warmth, ethical materials, and something they’ll actually enjoy wearing every day.
It’s a no-fuss layer that performs best during shoulder-season commutes, travel, and layering under a shell. While active users may want more breathability and structure (à la R1®), the Micro D remains a top-tier ultralight casual fleece in 2025—just as it has for over a decade.
