Rab Microlight Alpine vs. Electron Pro: which one to choose
Mountain GroupIf you are deciding between the Rab Microlight Alpine and the Electron Pro, start with the intended use: a jacket for frequent outings and everyday wear does not need to solve the same problems as an insulation layer intended primarily for cold mountains. Our choice would be the Microlight for versatility and the Electron when insulation weighs more heavily in the decision.
We are comparing the men's versions Microlight Alpine Hoody QDB-92, AW26 collection, and Electron Pro Hoody QDB-81. The figures correspond to a size M; they should not be applied to the old Microlight QDB-12 or the women's versions.
Quick answer
- Microlight Alpine: for combining hiking, climbing, travel, and everyday use with a single jacket.
- Electron Pro: to prioritize insulation in the mountains, with a moderate increase in weight.
Technical comparison
| Data, size M | Microlight Alpine QDB-92 | Electron Pro QDB-81 |
|---|---|---|
| Total weight | 428 g | 477 g |
| Fill power | 700FP, recycled down | 800FP, European goose down |
| Down fill weight | 152 g | 179 g |
| Outer fabric | 30D Pertex Quantum | 20D Pertex Quantum Pro |
| Rab fit | Regular | Regular |
The Electron adds 49 g in total weight and 27 g of fill. It also uses down with a higher fill power. This is a reasonable basis for choosing it when you are looking for more insulation, but it does not allow for the calculation of a specific temperature rating or an exact percentage of warmth.
When to choose Microlight Alpine
We would choose it if the majority of your outings alternate between hiking, stopping, and different activities, and you want to use the same garment outside the mountains. Before moving up a category, it is worth checking how much time you spend standing still and what other layers you are wearing. Buying more insulation than you need may result in the jacket spending most of the day in your backpack.
When to choose Electron Pro
The Electron makes sense if the main objective is to have a down layer for cold outings, climbing, and mountain stops. Our recommendation is based on the combination of fill, fabric, and design, not just the 800FP figure. If you anticipate long periods of waiting or more demanding cold, compare it with the Neutrino Pro as well.
Which one to take to the Pyrenees?
“Pyrenees” does not define a single situation. A sunny hike and a stop exposed to the wind need different solutions. To choose, specify the season, altitude, duration of stops, and whether the jacket will be worn while walking or reserved for when you stop. Between these two, we would start with the Microlight for varied use and move to the Electron when cold stops are an important part of the activity.
Frequently asked questions
Are they waterproof?
They do not replace a waterproof jacket. The water repellency of the exterior does not equate to protection against persistent rain. Plan for a compatible waterproof shell and enough space so you do not compress the insulation.
Does 800FP always mean more warmth than 700FP?
Not on its own. Fill power describes the expansion capacity of the down; you also have to consider the quantity, distribution, and fit. A size that compresses the down or leaves large air gaps can negatively affect the result.
Mountain Group Choice
For a versatile purchase, Microlight. For dedicating the jacket mainly to cold mountains, Electron. Try it on with the layers you will use and check shoulder mobility, neck closure, and hood adjustment.
