Thermal Underwear WROOM Level 1 — your first shield against the cold

A familiar situation when the frost tightens the air, yet you still have to keep moving?
WROOM Level 1 thermal underwear is made exactly for that — to keep you going when others freeze. It is your base layer of protection, the first tier of the insulation system that holds warmth while allowing your body to breathe.

This solution is not only for those who serve or work outdoors.
WROOM Level 1 is perfect for airsoft players, hikers, hunters, athletes, and everyone who chooses movement and activity instead of spending winter under a blanket.
It is lightweight, elastic, pleasant to the skin — and at the same time effectively retains heat even at –15°C. Combined with the second insulation level — comfortable down to –30°C.

Developed with experience, tested in practice

At WROOM, we don’t make “just warm clothing.” We create gear that works in the field.
Every element of our thermal underwear is designed to ensure functionality, durability, and maximum comfort in the cold.

Hypoallergenic fabric — comfort for any skin type

WROOM Level 1 is made of innovative fibers suitable even for sensitive skin.
It is hypoallergenic, doesn’t cause irritation, and stays pleasant to the touch even after many hours of use.

Antibacterial protection
We know that in field or dynamic conditions, washing clothes often is not always possible.
That’s why WROOM Level 1 has antibacterial treatment that prevents odors and keeps the fabric fresh even after long hours of active use.

Innovative Single Jersey + CoolPass fabric
We used technological Single Jersey structure, made of polyester with CoolPass microfibers.
It not only retains warmth but also instantly wicks moisture to avoid the “greenhouse effect.”
Your body stays dry, warm, and stable even under load.
Its thin, elastic knit allows the underwear to sit close to the body without restricting movement — even under gear.

Details that matter
• Seamless technology. Flat seams prevent rubbing and discomfort.
• Raglan sleeves. No shoulder seams for free movement under load.
• Elastic waistband. Softly secures the pants, doesn’t squeeze or interfere under armor or gear.
• High elasticity. Adapts to the body and maintains shape even after intensive use.
• Antibacterial treatment. Less odor, less irritation, more comfort.
• Compactness. Lightweight, takes minimal space — ideal for long trips.
