Celrien | AlpineTrek Long Sleeve Crew Thermal Shirt

A versatile long-sleeve thermal shirt designed for active days in changing climates.

Finding the right base layer for unpredictable weather often means choosing between too heavy and too light. This midweight thermal base layer top balances insulation with breathability for a wide range of activities.

• Midweight breathable fabric construction
• Moisture-wicking for active use
• Odor-resistant for extended wear
• Tagless design for added comfort

Versatile layering
The midweight fabric serves as an effective base layer, mid-layer, or outer layer depending on the conditions. The fitted style layers smoothly under heavier jackets without bunching.

Comfortable construction
Designed with a tagless neck to reduce irritation during extended wear. The built-in stretch allows the fabric to move with you rather than restrict your motion.

Temperature regulation
The breathable knit structure works to balance body heat, providing insulation when stationary and releasing excess warmth during exertion. Moisture-wicking properties draw sweat away from the skin.

Extended freshness
The fabric features natural odor-resistant properties that keep the garment fresh through repeated use. Ideal for multi-day trips where washing facilities are limited.
