Choosing between wool and technical headwear

Hat Buying Guide

Choosing the right hat by season, use and style

OD's Designer Clothing · Knowledge Hubs

With so many hat styles and fabrics, the right choice comes down to season, activity and the look you want. This hub works through the key decisions and head-to-head comparisons so you can buy the right hat with confidence.

Head-to-head

Snapback vs Dad Cap

Choosing between a structured street cap and a soft, low-profile one.

The difference

A snapback is high, structured and flat-peaked for a sporty street look; a dad cap is soft, low and curved for an understated one.

How to choose

Pick a snapback for a bold, street-led outfit and a dad cap for an easy, minimal everyday cap.

Wool vs Acrylic Beanies

Weighing natural warmth against easy-care value.

The difference

Wool breathes, insulates when damp and resists odour; acrylic is cheaper, machine-washable and colour-fast but breathes less and can pill.

How to choose

Choose wool or merino for warmth and comfort in real cold, and acrylic for a budget-friendly, low-maintenance beanie.

Season and use

Summer vs Winter Hats

Matching headwear to the season's job -- shade or warmth.

The difference

Summer hats prioritise breathability and sun cover with cotton, mesh and wide brims; winter hats prioritise insulation with wool and fleece knits.

How to choose

Build a small rotation: a breathable cap or bucket hat for summer and a warm beanie for winter.

Choosing a Running Cap

What to look for in a cap built for miles.

What matters

A running cap should be lightweight and breathable with a moisture-wicking sweatband, and ideally a water-repellent finish.

Where to look

Browse performance headwear from On Running (/collections/mens-on-running-caps) built for training and racing.

Choosing a Hiking Hat

Picking headwear for the trail and changeable weather.

What matters

A hiking hat needs sun protection or warmth for the season, durability and often a water-repellent or wind-resistant fabric.

Where to look

Berghaus (/collections/mens-berghaus-hats) builds outdoor headwear around weather-ready, hard-wearing fabrics.

Style decisions

Choosing by Face Shape

Matching a cap or hat silhouette to your features.

How it works

Structured high-crown caps add height and suit rounder faces; low, soft caps and wider brims balance longer or angular faces.

Tip

Try a few crown heights and peak shapes; the right proportion frames the face rather than overwhelming it.

Smart vs Casual Headwear

Knowing which hats lift an outfit and which keep it relaxed.

The difference

Flat caps, baker boys and felt hats read smarter and more classic; caps, beanies and bucket hats read casual and modern.

How to choose

Match the hat's formality to the outfit -- a flat cap with tailoring, a beanie or cap with denim and knitwear.

Investing in a Better Hat

What extra spend buys in a premium cap or beanie.

What you get

A better hat brings finer fibres, cleaner embroidery, a proper sweatband and stronger closures that hold shape and last.

Why it matters

A premium beanie in merino or cashmere, or a well-built cap, outlasts several cheap ones and looks better throughout.

Frequently asked questions

What hat suits me best?

Match the style to the occasion and your proportions: structured caps and beanies for casual wear, flat caps and felt hats for smarter looks, and wider brims for sun protection; try a few crown heights to see what frames your face.

What is the best all-round hat to own?

A plain cotton baseball cap and a wool beanie cover most of the year between them, giving casual summer shade and reliable winter warmth in versatile, easy-to-wear shapes.

Is an expensive beanie worth it?

If you feel the cold, yes; merino and cashmere beanies are warmer, softer and less itchy than cheap acrylic, resist odour and hold shape far longer, so the cost-per-wear is often lower.
