Micro Climate vs. Magic Shell - Cycling Jacket Comparison
By matt quann
TLDR:
Micro Climate - Water resistant / wind resistant, temp range 40-65, 155 grams, packable and lightweight. Magic Shell - Highly water resistant (the fabric is waterproof) / wind proof, temp range 55 degrees and below, 255 grams, packable, but you need some space. /
WHY WE DEVELOPED THE MICRO CLIMATE JACKET
For years, when someone asked for a jacket, the answer was simple: Magic Shell. It’s award-winning for a reason, delivering stretchy, breathable protection from rain and cool temperatures.
But there was one scenario where it wasn’t perfect: big temperature swings. In San Francisco, a ride can easily span a 15 to 20 degree shift, often layered with wind or fog. Conditions change fast, and sometimes you want the option to take a layer off without committing to stuffing a full shell in your pocket.
That’s why we developed the Micro Climate Jacket. A highly packable layer built for variability. Comfortable enough to wear all day, compact enough to stash when the sun finally wins.
The Micro Climate Jacket:
The Micro Climate Jacket is our most lightweight, packable outer layer, built specifically for variable conditions. It uses a custom-milled stretch-woven fabric developed for exceptional breathability and durability, the same advanced weaving process once used in elite performance swimwear. The result is a fabric that moves easily, recovers consistently, and feels barely there while riding.
Strategic lofted insulation is mapped across the jacket to trap warmth where it matters, without causing overheating during effort. Each fiber is permanently treated with a patented moisture-resistant finish that sheds light rain and dries quickly, without relying on a surface coating that can wash off over time.
A single rear pocket holds your ride essentials and doubles as a reversible stuff sack, so when temperatures rise, the jacket disappears neatly into itself.
Possible Micro climate scenarios.
1. Early Morning - 45 degree morning, temps rise to 58 and sunny -
2. Nice Afternoon, then the sun sets. - 62 degrees drops to 50 - lightweight long sleeve or short sleeve jersey, Micro Climate Jacket in pocket or bag. Put on the jacket when temps drop.
3. SF Specific - City escape. Fog and 55 in sf, 80 on Mt. Tam, 58 in Stinson beach. You know the drill (jacket, jacket off, jacket back on)
4. Wear it over a trail shirt 55-65 degrees (short sleeve / long sleeve base layer optional) take it off for the climbs, put it on when you’re having lunch and enjoying the views at the top.
5. Unknown ride - Not exactly sure where you’re going, where you may stop or what the weather will be like? Take this jacket with you!
We could go on and on, but the Micro Climate really excels at temp changes and can be custom tailored based on the layers worn underneath. There’s no penalty for taking this jacket with you, so you could avoid shivering, Ornot.
The Magic Shell:
The Magic Shell Jacket is built with a lightweight knit version of Polartec® PowerShield Pro®, delivering exceptional breathability, full wind protection, and reliable waterproof performance. After years of riding in it, we can confidently say it lives up to its name. Bicycling Magazine even recognized it with a Gear of the Year award.
Designed as a true do-it-all shell, it’s soft and stretchy enough to layer comfortably over a jersey or midlayer, depending on the conditions. The rear pocket holds ride essentials like a phone or snacks.
While the fabric itself is waterproof, we also tape the seams for maximum waterproofing, all without harmful PFAS 'forever chemicals'. The Magic Shell is a deliberate balance: weather protection without sacrificing breathability during high-output efforts.
Possible Magic Shell scenarios:
1. 50 degrees all day long - (layer with a thermal jersey)
2. 45 degrees all day long and it’s probably going to rain… (see above)
3. 33 degrees, sunny, must get outside for a ride! (Thermal jersey + base layer)
4. Grinduro 2019 - 50 degrees at the start. 30 degrees and hailing at the tops of the climbs. (Thermal jersey + base layer)
5. 50 degrees and rain - MUST GET OUT OF THE HOUSE - Go for it, don’t forget a cap.
Final Verdict.
Everybody wins. There isn’t a single “better” jacket, just the right tool for the conditions.
If you ride in truly cold weather or steady rain, the Magic Shell is your move. If your rides are defined by big temperature swings, dry cold, or fall and spring variability, the Micro Climate is the better fit.
They’re built for different weather. If you ride in all of it, you might need both, Ornot.
