Longjohns

Stay warm on British hillsides with proper thermal base layers. Whether you're tackling a winter Munro, working outdoors in the cold, or simply need reliable warmth for everyday wear, a good pair of longjohns makes all the difference. Our range includes both military surplus thermals and outdoor-grade base layers designed for British conditions.

How to Choose Your Longjohns

Consider the fabric weight. Lightweight options (around 150-180 GSM) suit high-output activities where you'll be moving constantly. Midweight thermals (200-250 GSM) offer the best all-round performance for British conditions. Heavyweight base layers provide maximum warmth for static use or extreme cold.

Choose your material carefully. Merino wool regulates temperature naturally and resists odour over multiple wears—ideal for multi-day trips. Synthetic fabrics dry faster after exertion and typically cost less. Many outdoor professionals prefer merino for comfort against the skin, while synthetics excel when durability and quick-drying matter most.

Think about fit. Base layers work best when snug against your skin, allowing moisture to wick away efficiently. Loose longjohns trap cold air and reduce thermal performance. Check sizing guides carefully—military surplus often uses chest measurements rather than standard S/M/L sizing.

Match warmth to activity. A winter hillwalker standing at summit cairns needs more insulation than a fell runner generating heat through movement. Consider your typical use before buying the warmest option available.
