Softshell jackets are usually made from woven polyester or nylon, often blended with elastane for stretch. Some fabrics are a single woven layer, while others combine a face fabric with a membrane and a fleece or tricot backing. That difference explains why one softshell can feel light and airy while another feels warm, windproof and more resistant to rain.
Quick answer
Most softshell jackets use a polyester or nylon outer face, a small amount of elastane when stretch is needed, and an optional fleece or tricot inner surface. Some include a polyurethane-based membrane for stronger wind and water resistance. Not every softshell has three layers, and not every softshell is waterproof.
Softshell is a category of flexible outerwear fabric rather than one fixed material. It is designed to balance movement, comfort, wind protection and light weather resistance. Compared with a waterproof hardshell, it normally feels softer and allows more air or moisture to move through. Compared with a fleece, it usually blocks wind and handles abrasion better.
The balance changes from fabric to fabric. A runner may need a light, air-permeable woven softshell. A winter work jacket may use a membrane and a brushed backing. Both can be sold as softshells, but they do not perform in the same way.
Polyester is widely used for the outer face and the inner fleece or tricot. It offers broad choices in weight, texture, color and finishing. It is a practical option for printed fabrics and for programs that need a consistent surface appearance.
Nylon is also used in performance softshells, especially where a smooth hand feel and good abrasion resistance are priorities. The final durability still depends on yarn, weave, weight and finishing, so fiber name alone does not determine quality.
A small percentage of elastane can provide two-way or four-way stretch. More stretch is not automatically better: recovery, dimensional stability and seam behavior must also be checked. Some mechanical-stretch fabrics achieve movement through yarn and weave construction without elastane.
Some softshells include a thin membrane, commonly polyurethane-based, between the face and backing. It can improve wind resistance and water protection but may reduce air permeability. Other softshells have no membrane and rely on a dense weave plus a surface finish.
A brushed fleece back adds warmth and a soft feel. A lighter tricot back can protect a membrane and help the fabric slide over layers without adding as much insulation. Unbacked woven softshells are lighter and better suited to warm conditions or high-output activity.
A durable water-repellent finish helps droplets bead on the face fabric. It is not the same as a waterproof membrane, and it does not seal stitch holes. Its performance can decline with wear, dirt and repeated washing.
| Construction | Typical structure | Main advantage | Common limitation |
|---|---|---|---|
| Woven softshell | Single woven layer, sometimes double-weave | Light, breathable and flexible | Limited warmth and rain protection |
| Fleece-backed softshell | Woven face bonded to a brushed back | Comfort and moderate warmth | Heavier and less suitable for warm weather |
| Membrane softshell | Face fabric, membrane and backing | Stronger wind and water protection | Usually less air-permeable |
| Insulated softshell | Softshell outer with a separate insulating layer | More warmth for cold conditions | More bulk and slower drying |
Most softshell jackets are water-resistant rather than fully waterproof. They can handle wind, light drizzle or brief snow exposure, depending on the fabric and construction. Prolonged rain can pass through the face fabric, seams, zippers or openings.
A membrane softshell may achieve a stated hydrostatic-pressure result, but the fabric result is not the same as finished-garment protection. If the seams are not sealed, water can enter through needle holes. Buyers should confirm the test method, target result and whether the report covers fabric or the completed garment.
For sustained rain, a waterproof hardshell construction is generally the safer choice.
| Feature | Softshell | Hardshell |
|---|---|---|
| Primary role | Movement, comfort and moderate weather protection | Reliable wind and rain protection |
| Feel | Soft, quiet and often stretchy | Crisper and more structured |
| Air permeability | Often higher, especially without a membrane | Usually lower |
| Water protection | Usually light to moderate | Designed for sustained rain when properly specified |
For hiking and active use: prioritize stretch, low weight and air permeability. A membrane-free woven construction may feel more comfortable during steady movement.
For workwear: focus on abrasion resistance, snagging, colorfastness, pocket reinforcement and the safety standard required by the end market. High-visibility compliance depends on the complete garment design and certified materials, not on softshell fabric alone.
For skiing and cold weather: consider a fleece backing or separate insulation, plus wind resistance and compatibility with other layers. Do not assume that warmth and waterproof performance increase together.
For hunting: surface noise, color, print durability and abrasion resistance may matter as much as weather protection. Test the actual fabric because “brushed” or “quiet” are subjective descriptions.
For uniforms and everyday wear: balance appearance, comfort, wash durability and cost. A heavy membrane fabric may be unnecessary when the jacket is mainly used for commuting or indoor-outdoor work.

A fabric description such as “300 GSM, 10K waterproof softshell” is not enough on its own. Ask for the complete construction and the test method behind every number. Two suppliers can use the same marketing description for noticeably different fabrics.
No. Fleece is usually a knitted insulating fabric. A softshell normally has a woven outer surface that offers more wind and abrasion resistance, although its inner side may be fleece-backed.
No. Softshells can be single-layer woven fabrics, double-weave constructions, two-layer bonded fabrics or three-layer laminates. The product brief should identify the actual structure.
Neither is automatically better. Polyester offers broad color, texture and printing options. Nylon may be chosen for a particular feel or abrasion requirement. Compare the finished fabric rather than choosing by fiber name alone.
A tight weave reduces air movement, while a membrane can block more wind. The jacket's zippers, cuffs, hem and fit also affect how much wind reaches the wearer.
