FAQ: Outerwear Basics & Selection
How do I choose the right size jacket?
Choose the right jacket size by measuring your chest and comparing it to the brand’s size chart, leaving 1.5–2.5cm for layering space. The shoulder seams should align with your shoulders, and sleeves should extend to your wrist. Most buyers miss this: jackets too tight restrict movement, while oversized ones trap cold air. The Jecket fit guide recommends 2cm layering room for optimal comfort in colder conditions. → How to Choose the Right Jacket Size
What's the best jacket for mild weather?
The best jacket for mild weather (10–20°C) is a softshell or lightweight windbreaker with a breathability rating of 10,000g/m²/24h. Softshells offer stretch and wind resistance, while windbreakers are packable and ideal for variable conditions. Avoid heavy insulation—focus on materials like polyester or nylon with DWR coatings for light rain. → Softshell & Windbreaker Jackets
Which jacket materials are best for rain?
Waterproof jackets require a hydrostatic head ≥1,500mm (ISO 811 standard) and a DWR coating for surface water repellency. Gore-Tex and eVent are top choices, offering both waterproofing and breathability. Avoid water-resistant jackets for heavy rain—they lack the membrane needed for prolonged exposure. → Waterproof & Breathable Guide
What is the difference between a shell jacket and a hardshell jacket?
A shell jacket is lightweight (20D–30D) and designed for layering, while a hardshell jacket uses thicker fabric (40D–80D) for abrasion resistance and extreme weather protection. Hardshells feature fully taped seams and waterproof membranes, making them ideal for mountaineering. Shells are better for casual use or light rain. → Shell vs. Hardshell Guide
How warm is a 700-fill down jacket?
A 700-fill down jacket provides ~1.5 CLo (ASTM F2732), suitable for temperatures down to -10°C. Fill power measures loft—the higher the number, the warmer and lighter the jacket. For colder conditions, consider 800+ fill or synthetic insulation.
How to layer clothes effectively under a jacket?
Layer clothes effectively by starting with a moisture-wicking base layer, adding a 2–5mm fleece mid-layer for insulation, and topping with a shell or hardshell jacket. Avoid bulk by choosing thin, high-performance fabrics. For temperatures below -15°C, increase mid-layer thickness or add a down vest. → Winter Layering Guide
Can you wear a hardshell jacket in summer?
Hardshell jackets can overheat above 15°C unless they have pit zips and a breathability rating ≥20,000g/m²/24h. For summer, prioritize lightweight shells or softshells with ventilation features.
How often should you wash a waterproof jacket?
Wash waterproof jackets every 20 wears using a tech-specific detergent to maintain DWR coatings. Reproof after every 10 washes to restore water repellency. Avoid fabric softeners—they degrade waterproof membranes. → Jacket Care Guide
What are the key takeaways for outerwear buyers?
Match insulation thickness or fill power to your coldest expected temperature. Prioritize fit—allow 1.5cm layering space in shoulders/chest. For rain, verify hydrostatic head ≥1,500mm (ISO 811).
Frequently Asked Questions
How do I measure myself for a jacket?
Measure your chest at its widest point and compare to the brand’s size chart. Leave 1.5–2.5cm for layering space.
What’s the warmest type of winter jacket?
Down jackets with 800+ fill power provide the most warmth, suitable for temperatures below -15°C.
Can I wear a rain jacket in winter?
Yes, but pair it with insulating layers—rain jackets alone lack warmth for cold conditions.
How do I know if a jacket is waterproof?
Check the hydrostatic head rating—≥1,500mm (ISO 811) indicates waterproofing.
What’s the difference between Gore-Tex and eVent?
Gore-Tex uses a microporous membrane, while eVent employs direct venting for higher breathability.
How do I store a down jacket?
Store down jackets uncompressed in a cool, dry place to maintain loft.
Can I machine wash a waterproof jacket?
Yes, use a front-loading machine and tech-specific detergent to preserve waterproofing.
What’s the best jacket for hiking?
A hardshell jacket with a hydrostatic head ≥10,000mm and pit zips is ideal for hiking.
