For winter camping, let's talk about outerwear, the outermost layer you wear.
There are three main types of outerwear.
Material-based selection
Let's look at the advantages and disadvantages of each.
| Strong Points | Disadvantages | |
| down | Lightweight and highly insulating. | Weak against water |
| Synthetic fiber | Water-resistant and easy to maintain, including washing. | It doesn't have the same insulating ability as down, and it's bulky. |
| Fleece | It is breathable and easy to regulate temperature. | It's too breathable, making it susceptible to fear. It's also bulky. |
down
It has high heat retention capabilities by trapping air in the gaps between the feathers.
The feathers on the chests of waterfowl are considered a luxury item, and when you consider that they grow on birds that live in cold climates, you can imagine how warm they must be.
However, when wet, the feathers contract like cotton candy shrinking, making it impossible to trap air and thus losing its ability to retain heat.
Synthetic fiber
While it offers less absolute warmth compared to down, it is less susceptible to performance degradation from sudden rain or sweat during activities.
Earlier I used the analogy of cotton candy, but synthetic fibers can be compared to sponges.
While sponges cannot trap as much air as feathers, their bulk (volume) does not change even when they absorb water.
In other words, its ability to retain air remains unchanged even when wet.
However, while down feathers shrink considerably, sponges do not. That's a disadvantage of synthetic fibers.
Fleece
The advantage of fleece is its versatility. When it's very cold, it can be used as a middle layer in a layering system, and when it's sunny and warm, its breathability allows it to be used as an outer layer.
However, in terms of heat retention, it is still a step below the two mentioned above.
Recommended winter clothing
Based on these points, I will now introduce some recommended products that prioritize warmth and cost-effectiveness.
