7 Lightweight Knits Every Man Needs This Summer
When summer finally arrives, the clothes we reach for tend to become increasingly casual as the temperature rises. Shirts are subbed for T-shirts, tailoring disappears entirely unless there’s a wedding involved, and before long, everyone looks like they’re dressed for a trip to the beach… whether they are or not.
Lightweight knitwear offers a way around this. Whether it’s a fine-gauge crew neck, a knitted polo or a button-through cardigan, the addition of a knitted layer brings sophistication and a touch of old-world Riviera style without adding too much unwanted insulation.
The trick to nailing it lies in the fabric, fit and style of the piece in question. Modern blended knits can be breathable enough for summer while looking considerably more polished than a hoodie or overshirt. Here’s what you need to know.
Buying Considerations
Gauge
The ‘gauge’ refers to the density of the knit and is one of the biggest factors in determining how warm a garment feels. For summer, look for breezy, fine-gauge knits, which use thinner yarns and a tighter construction to create a lightweight, breathable fabric.
Chunky cable knits have their place, sure, but it’s not during a heatwave.
Material
The fibre used in the knit will significantly impact comfort and the garment’s overall feel. People hear knit and think wool, but that’s just the tip of the iceberg.
Cotton is durable and easy to care for, linen offers maximum breathability, and merino wool is famously excellent at regulating temperature. Blended fabrics often provide the best of both worlds, combining, for example, the softness of cotton with the cooling properties of linen or silk.
Look at the label carefully before you commit.
Fit
Fit, as we always say, is everything. And that’s no different when it comes to a lightweight knit. Summer knitwear should skim the body rather than cling awkwardly to it or hang clumsily off it.
A little room allows air to circulate and creates a more relaxed silhouette that’s in keeping with the general vibe of summer style. While slim fits still have their fans, a slightly boxier cut tends to feel more contemporary and comfortable in the heat.
Details
Pay attention to the little things. Ribbed hems and cuffs help a garment retain its shape, while details like camp collars, quarter zips or button-through fronts can dramatically alter how a piece looks and functions in the heat.
Things like colour and pattern may not affect how the garment functions, but they play a key role in deciding whether it feels summer-appropriate or not.
Price
Unfortunately, quality knitwear isn’t cheap, but it’s worth investing in. More expensive pieces tend to use superior fibres, better construction techniques and fully fashioned knitting, which helps garments hold their shape better over time.
That said, there are plenty of excellent options at mid-market prices, particularly for cotton and cotton-linen styles.
Key Styles
Merino Polo
- wahts Hall Longsleeve Merino Polo
- Reiss Manor Merino Wool Short-Sleeve Polo Shirt
- M&S Autograph Pure Extra Fine Merino Wool Knitted Polo Shirt
Merino often crops up early on in conversations about knitwear due to its natural temperature-regulating ability, but usually in connection with staying warm. What you may not realise is that the qualities that make it perfect for winter weather also make it a great option for summer. When it’s hot, the fabric wicks sweat and releases it into the air, keeping you cool, dry and comfortable.
A merino polo capitalises on this, harnessing everything that’s great about the fabric and presenting it as a highly versatile garment that can be worn with everything from shorts and trainers to summer tailoring.
Smarter than a tee, more intentional than a classic pique polo and perfect for battling the heat.
Crochet Short-Sleeve Shirt
- Reiss Meadows Cotton Crochet Button-Through Shirt
- Wax London Porto Ecru And Orange Stripe Crochet Knitted Shirt
- Percival Wade Crochet Boxy Shirt
With their loose weaves that promote airflow, crochet shirts are great for keeping cool, and the unique texture brings a distinct visual element to summer fits, too. These shirts work particularly well in eye-catching prints and patterns, acting as the main event of an otherwise understated outfit, drawing the eye and giving the whole thing a focal point.
But you don’t have to go bold. The great thing about a crochet shirt is that the fabric’s texture alone gives the garment visual interest, making it possible to create understated summer outfits without veering into boring territory.
Fine-Gauge Crew Neck
- Velasca Colletta
- wahts Hampton Cotton Merino Pullover
- Reiss Wessex Merino Wool Crew Neck Jumper
The humble crewneck may not be the sexiest item in the summer knitwear canon, but it’s arguably the most useful. A lightweight cotton, linen or merino version can be draped over the shoulders during the day, tied around the waist when the sun comes out or thrown on when the temperature inevitably dips after sunset.
It’s also one of the easiest styles to dress up. Worn with tailored trousers, it feels quietly sophisticated; paired with shorts and loafers, it channels the effortless elegance normally associated with the French Riviera.
The key is keeping things lightweight. Save the chunky fisherman knits for autumn and winter.
Quarter-Zip
- Lestrange The 24 Merino Half Zip
- Velasca Orgosolo
- wahts Luke Extrafine Merino Half Zip Pullover
Part jumper, part sweatshirt, the knitted quarter-zip occupies a useful middle ground within the modern man’s wardrobe. It’s more refined than your average sweatshirt, but it retains the same easy-going versatility, making it ideal for travel, weekend wear and relaxed office dress codes.
For summer, opt for lightweight cotton or merino styles in neutral shades. Worn with the zip partially open, they offer a little extra ventilation in high temperatures. Meanwhile, the collar creates a slightly smarter appearance than a standard crew neck, making it a useful option for occasions that call for a touch more polish.
Light Cardigan
- Todd Snyder Linen Cardigan
- Massimo Dutti Linen Knit Cardigan
- Arket Cotton Cardigan
The cardigan has undergone something of a revival in recent years. Once associated with university professors and elderly relatives, it has become one of menswear’s most versatile layering pieces, embraced by everyone from Hollywood’s leading men to fashion’s biggest tastemakers.
A lightweight cardigan works particularly well in summer because it can be taken on and off with ease. When thrown over a T-shirt, polo or linen shirt, it offers just the right level of warmth for cooler evenings without feeling restrictive.
Look for fine-gauge cotton or linen-blend options that feel soft, breathable and easy to wear.
Knitted Tank
- Arket Cotton Vest
- COS Knitted Linen Tank Top
- wahts Irwin Crochet Spencer V-Neck
The knitted tank won’t be for everyone, but it’s worth considering if you’re looking to add a little variety to your summer wardrobe. Lightweight sleeveless knits offer texture and visual interest without significantly increasing warmth, making them surprisingly practical when layered correctly.
Worn over an Oxford shirt, they bring a subtle Ivy League flavour to an outfit. Alternatively, a lightweight knitted vest can be layered over a plain T-shirt for a more contemporary look. Either way, the trick is to keep everything relaxed and avoid anything too fitted or overly preppy.
Zip-Through Cardigan
- Luca Faloni Zip Cardigan
- Suitsupply Dark Grey Merino Zip Cardigan
- Luca Faloni Zip Cardigan
Sitting somewhere between a cardigan and a lightweight jacket, the zip-through cardigan is one of the most practical pieces you can own. The front zip allows for easy temperature regulation while the knitted construction keeps things softer and more refined than a traditional overshirt or track top.
It’s particularly useful during those awkward transitional periods that characterise the British summer. Worn open over a T-shirt, it functions as a light layer for breezy afternoons. Zipped up, it provides enough warmth for cooler mornings and evenings.
For maximum versatility, stick to classic colours like navy, grey or ecru.
