Winter surrenders, but your adventures don't. You need a jacket that's as tough as you are. Forget flimsy windbreakers — we're talking about conquering trails, powering through challenges, and staying on top of your game, all while battling the elements. Here's how to find the best lightweight jacket for your spring and summer expeditions that will last you for years to come.
How should a spring or summer jacket fit?
Unlike insulated winter jackets that trap heat, summer jackets prioritise breathability and a comfortable fit for warmer weather. You want to be able to swing your arms freely, reaching for your camera or trail mix without feeling restricted. Avoid a tight squeeze that could lead to overheating, but be wary of too much wiggle room too. A loose fit lets cool air circulate, but excess bagginess can billow in the wind and snag on branches. For activities like hiking or biking, choose a summer jacket that layers well and offers easy pocket access even with a rucksack on.

Choosing a spring or summer jacket: What to consider
With so many jacket options available, you might be wondering what type of jacket is best for spring's unpredictable weather? And how about those sizzling summer days? Here are some of the essential factors you need to consider.
Breathability
Spring and summer mean exertion, and with exertion comes sweat. A jacket that traps moisture can lead to discomfort and exhaustion in warmer climates. Look for lightweight, breathable fabrics such as nylon, polyester, or our exclusive proprietary fabric. ThruDark's spring and summer jackets are crafted from innovative synthetic blends treated with a Durable Water Repellent. They’re engineered to wick moisture away from your skin and keep you cool and focused.
ThruDark's pick: Vanguard Jacket - is a mid weight, waterproof hard shell designed for fast paced outdoor pursuits including trail running and thru-hiking.
Pursuit or activity
Not all missions are created equal. A high-altitude trek demands a different layer than a desert patrol. Pick your pursuit:
- High-cardio: Opt for ultralight, ultra-breathable running jackets that prioritise airflow.
- Backpacking: Packable windbreakers offer protection from light wind and rain while minimising weight.
- Extreme Expeditions: Durable jackets with water-resistant finishes and tactical features like reinforced elbows and pockets for gear are ideal.
Hood or no hood
Deciding between a hooded and a non-hooded jacket is a simple trade-off, depending on whether you prioritise full coverage with the hood (even though it adds extra weight) or prefer the lighter option without it. It's important to consider that in very cold conditions, up to 45% of body heat can be lost through the head, so if you're venturing into cooler temperatures, it's wise not to compromise on weight. However, even in summer, head protection from sudden downpours or biting winds can be crucial. A stowable hood offers the best of both worlds: deploy when needed, disappear when not.

Pocket features
Spring and summer jackets prioritise lightweight construction and breathability, so pockets tend to be more streamlined compared to winter jackets.
Some spring/summer jackets, particularly those designed for outdoor activities, feature larger cargo pockets with flaps or zippers. These are handy for carrying additional items like protein bars and recovery gels or drinkware.
Waterproof construction
Spring showers and summer storms are a reality, so choose a jacket with a water-resistant or waterproof finish. Anticipate navigating heavy rain or wet environments? A fully waterproof jacket with strategically placed vents might be the way to go. But for those who prioritise breathability for high-exertion activities, a water-resistant shell should suffice for sudden downpours.

Weight and compressibility
Every gram counts. Summer jackets are all about shedding weight and stowing away compactly. Unlike winter coats, they're not meant for constant wear. This is where synthetic materials shine. Unlike down, which excels at warmth but packs down larger, synthetic fabrics like nylon or polyester are naturally lightweight and compress incredibly well.
ThruDark's pick: Oryon Windguard Jacket - A packable, windproof shell jacket designed for maximum weatherproofing at a minimal carry burden whilst hiking, trekking, or on multi-day expeditions.
