A winter jacket that excels in offering both cold and wet weather protection? It’s a tough ask, but a long autumn, winter and springtime test period has given me plenty of chances to test the Kathmandu Trailhead’s weather-thwarting qualities, and it’s gone about its business in a consistently reliable way.

Weather protection
As the title suggests, the lean 573.6g (for a men’s medium) Trailhead 2-layer Insulated Rain Jacket is built for both cold and wet weather. While it lacks the puffer jacket looks of many of its rivals, it’s warmer than it looks, Kathmandu’s 80gsm NovaLOFT insulation holding its own against the January cold snap in the UK and on hilly escapades in the Malvern and Mendip hills. But if you’re going into truly bracing sub-zero conditions in exposed and mountainous environments, you will need something thicker and more wind-stopping.
Despite my best efforts, the fully-taped waterproof shell has consistently withstood penetration from precipitation, with the Durable Water Repellent (DWR) finish beading rain, snow and sleet during winter rambles, extended stints coaching from the football sidelines and commuting on the bike. Some users have noted that the seams let water in but I’ve yet to experience any seepage.

Breathability and Ventilation
The Trailhead 2L boasts a waterproof rating of 15k, but it matches this with a breathability rating of 15k as well, and this helped me stay relatively sweat-free on higher-paced hikes and cycling to work. This is achieved with a lack of venting.
Fit and Freedom of Movement
The adjustable cuffs, full-length zipper with garage and a drawcord hood don’t just prevent sneaky breezes from getting inside, but they offer further comfort in what’s a cosy yet unrestrictive jacket.
The sizing feels true and the versatility of this jacket – I’ve used it for hiking, commuting on the bike, football coaching and everyday wear – is further evidence of its comfortable feel in a variety of locations and activities. Unlike a classic puffer jacket, it’s also easier to stash in a bag and feels sleeker when on the bike and trails.

Portability and Weight
Features include internal chest and mesh pockets, as well as two zip hand outer pockets that’ll store gloves, snacks and keys. Further points are scored with the 100% recycled outer shell. It feels lightweight for something that provides impressive warmth, and it compresses down into a satisfactory bundle for travel.

Visibility and Safety
Male hikers get a choice of three colours, with the ‘Steel Grey’ easily being the most visible compared to the ‘Night’ and ‘Black Stingray’ option tested here. Females also get Black Stingray, ‘Natural’ and ‘Light Quartz’. Extra visibility flashes are also absent, but the material does glow a touch when exposed to car headlights.
Value for money
£175 is a lot to pay but the durability feels strong, while its ability to protect from both the cold and rain heighten the versatility of the Trailhead.
Sustainability
There’s a 100% recycled outer shell and Kathmandu is part of the global B Corp movement.
Suitable for
Hikers wanting a lightweight jacket that can handle both rain and chills in above zero conditions.
Should you buy it?
It's not cheap, but the cold weather and rain-thwarting abilities of the Trailhead make this a versatile and lightweight contender for walks from autumn to spring.
