Functional base layers at Recon Company – base layers for duty, operations and the outdoors

A functional base layer isn’t just about comfort – it’s the first layer of protection between your body and your kit. Anyone on duty, on a training exercise or out in the field knows that if your base layer fails, your body will get cold. At Recon Company, we select our range of base layers according to the same criteria we apply to our own development projects for law enforcement agencies – moisture management, fit under load-bearing systems and durability in long-term use. For over 30 years, we’ve known which materials work in practice and which fall apart after the third week of training.

Merino or synthetics – the right material for your purpose

The choice of material determines everything else. Merino base layers reliably regulate body temperature, inhibit odour formation thanks to their antibacterial properties and keep you warm even when wet – qualities that become immediately apparent during multi-day marches or when bivouacking without the option to change. Synthetic performance base layers made from polyester or polyamide dry faster, are more resistant to mechanical abrasion and are cheaper to buy – a clear advantage for intensive training periods where several sets need to go through the washing machine. Blended fabrics combine the best of both worlds: the softness and temperature regulation of merino wool with the tear resistance of synthetic fibres.

Short-sleeved, long-sleeved or thermal undershirts – choose the cut according to temperature and task

Short-sleeved base layers are the standard for moderate temperatures and physical exertion – breathable, close-fitting and discreet under a uniform or combat fatigues. Long-sleeved base layers protect the forearms from abrasion caused by rails, harnesses or undergrowth, and form the first thermal layer in the layering system when it’s cold. Thermal base layers come into play when temperatures drop and insulation is required without restricting freedom of movement. Flat or seamless seams are no minor detail here: anyone on the move for hours on end with body armour or a rucksack will notice every pressure point.

Fit under tactical gear

A tactical base layer must disappear beneath the combat uniform without adding bulk. This means: a close-fitting cut, a back that is long enough – so that kidney protection remains secure when wearing equipment – and elasticated cuffs that do not bunch up, even when worn under gloves. If you’re looking for compression properties, you’ll find compression undershirts that provide additional stabilisation for the muscles during prolonged exertion. For direct use under MOLLE carrying systems , we always recommend testing the garment with your full kit – how it fits on a hanger and how it fits under a 20 kg load are two very different things.

Our range: suitable for duty from the barracks to the field

We stock functional base layers from brands we know and have tested ourselves – ranging from sturdy everyday options for training and drills to high-quality merino base layers for demanding conditions. There’s a simple principle for making the right choice: duration of use and temperature range determine the material, whilst the intended purpose determines the cut. If you’re looking for the rest of the layering system, you’ll find suitable functional base layer trousers , as well as shirts and mid-layers , right here.

• Long-sleevedmerino base layer : Stays odour-free during multi-day outings and temperature changes – no need to change your base layer, no problem.
• Synthetic technical undershirt: Dries in minutes after strenuous sessions – ideal for training and frequent washing.
• Thermal base layer: As the first thermal layer in the layering system, it bridges the gap between the skin and combat clothing in cold conditions.
• Compression shirt: Stabilises muscles during long-distance marches and reduces fatigue under sustained physical exertion.
• Seamless base layer cut: Eliminates pressure points under body armour or a rucksack – particularly important during operations lasting several hours.
