Clothing and Layers

The layering system, what fabric actually does, and the chemistry that changed.

Updated

Clothing is the slowest-moving category in outdoor gear, which is why these reviews hold up better than most. Three layers, chosen for what they do rather than what they cost.

The system

Cotton is the one real mistake

It holds water, stops insulating when wet, and takes a day to dry. That is uncomfortable in mild weather and dangerous in cold. This is the single most useful thing to know about outdoor clothing and it has not changed in fifty years.

Fleece weights

Sold as roughly 100, 200 and 300. A 100-weight or a grid fleece is the modern default: it breathes far better than solid pile for the same warmth, dries faster and layers without bulk. A 300 is for standing about, too warm to walk in.

What actually changed: the water-repellent chemistry

The move away from PFAS finishes is now regulated in several markets. The replacements work nearly as well and wear out faster, which turns reproofing from something you could ignore into a habit. Wash a shell when it stops beading and re-treat it; a grubby membrane wets out long before it fails.

Travel clothing, specifically

The test is whether it dries overnight in a bathroom. Recycled polyester and nylon blends do; cotton and linen do not, and that is the difference between washing things in a sink and carrying them dirty. Mid-tones and patterns hide a day's wear. Pockets that close are the most useful feature and the rarest.

And the sustainable answer, which is not a purchase

Manufacturing dominates the footprint of any garment, so the lowest-impact version of a thing is the one you already own. Most serious brands now run repair and resale programmes, and using them beats buying the recycled-fabric replacement. Fleece also sheds microplastic in the wash, so wash it less, cool, in a mesh bag.
