Base Layer Bottoms: Thermal Leggings for Hunting UK
Stay warm and dry with Hillman's thermal base layer bottoms. Ideal for hunting, hiking, and outdoor use in cold UK weather. Breathable, soft, and durable.
When the cold bites and the wind never lets up, staying focused outdoors means starting with the right layers. Base layer bottoms are the foundation of any serious hunting or outdoor setup in the UK: whether you're on a dawn stalk, perched in a high seat, or hiking across wet terrain.
That’s why Hillman designs thermal leggings, long johns, and hunting base layers built not just for warmth, but for breathability, mobility, and all-day comfort. With options like merino wool base layer bottoms, our collection gives you the edge when conditions turn cold and unpredictable.
Why Base Layer Bottoms Matter for UK Hunters
In the British countryside, the difference between a successful outing and a miserable one often comes down to what you wear closest to your skin. Base layer bottoms aren’t just for extreme cold; they regulate moisture, keep muscles warm, and help prevent fatigue during long days in the field.
Whether you’re deer stalking in damp woodland, pheasant shooting on open farmland, or spending hours in a static high seat, having the right thermal base layer bottoms can keep you alert and mobile. They're designed to work in tandem with outerwear, giving you warmth without weight, and movement without bulk.
Hillman's designs take that even further. Each pair in our range is shaped to match natural motion, with just the right amount of flexibility and grip. And because UK weather doesn’t wait, our base layers perform whether it's raining, sleeting, or just bitterly cold.
Key Features of Thermal Base Layer Bottoms
When choosing the right thermal base layer bottoms for hunting or outdoor use, details matter. It’s not just about insulation — it’s about how well your clothing supports your performance in real terrain.
Merino wool is at the heart of our premium models, offering natural temperature regulation, odour resistance, and a soft, itch-free feel. Unlike synthetic fabrics, merino stays warm even when damp and is ideal for layering under outdoor trousers or waterproof overtrousers.
A good fit is essential. Hillman’s base layer leggings are cut close to the body to trap warmth without restricting movement. Flat seams minimise friction during long treks, and the elasticated waist ensures a secure, comfortable hold, even under additional layers.
Breathability is another key factor. Trapped sweat can cool the body too quickly in cold conditions. That’s why our designs focus on moisture-wicking performance, keeping skin dry while allowing excess heat to escape when activity levels rise.
Finally, durability. Every stitch, waistband, and hem is made to hold up against repetitive movement, multiple washes, and rugged conditions. These are hunting base layers built to endure.
Designed for Real-World Conditions in the UK
British weather rarely stays still. Cold mornings, damp afternoons, and wind-swept hills demand base layers that adapt. That’s why Hillman’s thermal base layer bottoms are crafted specifically for the unpredictability of the UK field.
In dense woodland or open moors, the right base layer leggings provide critical support against sudden drops in temperature. Whether you’re pushing through thick cover or sitting still during a long stalk, the fabric must offer consistent warmth without overheating.
Each Hillman piece is tested for real use, not just lab specs. The merino wool base layer bottoms are perfect for long days with minimal shelter, while our compression leggings deliver extra muscle support during more active pursuits like upland hunting or field sports.
Built to be worn under everything from waterproof hunting trousers to moleskin shooting trousers, these bottoms form a breathable yet insulating layer. That means you can move, wait, and shoot in comfort, without constantly adjusting your kit.
Find Your Ideal Fit: For Men and Women
A quality base layer should fit like a second skin. Not too loose to bunch under trousers, not too tight to restrict blood flow or movement. That’s why Hillman offers base layer bottoms in a full range of sizes and fits, tailored for both men and women.
Our men’s base layers focus on anatomical support, especially around the waist and thighs, with a structure that allows full mobility when bending, kneeling, or climbing. For women, the fit is refined around the hips and lower back for better contouring and comfort during long outings.
Options include women’s thermal leggings designed for extended wear, layered under shooting trousers or waterproof outerwear. The waistband is soft but secure, with no slipping or gaping even during active movement.
Whether you prefer a classic long johns style or modern compression thermals, the goal is the same — to give you a foundation of warmth, support, and all-day comfort, without distractions.
Layer Smarter: Pair with the Right Hunting Gear
The best base layer bottoms are only as good as what you wear over them. For full protection in the field, they should work seamlessly with your outer garments. That’s why Hillman’s designs are made to match with our waterproof hunting trousers, shooting trousers, or even traditional tweed hunting trousers.
During cold and wet hunts, pairing thermal base layer bottoms with insulated hunting trousers ensures your lower body stays warm without trapping moisture. In early-season outings, wear your breathable leggings under lightweight field trousers to stay cool while moving fast through cover.
Every detail — from length and stretch to cuff finish — is shaped to avoid friction with boots, prevent bunching, and allow easy layering. This way, whether you’re on a high seat, stalking game, or walking a full day, your gear won’t hold you back.
It’s not just about staying warm. It’s about staying focused. When your hunting clothing performs like it should, all you have to think about is the next move.

With the right fit, every move feels effortless, and every layer counts.
