The Tempo Thermal T-Shirt is a seamless polypropylene base layer designed to pull sweat off your skin and keep you dry during high-output activity. Its moisture-wicking fibers and multi-zone knit make it a next-to-skin layer for running, hiking, cycling, and ski touring, where staying dry matters more than staying warm on its own. As a base layer built for active wear, the Tempo works as the foundation of a layering system rather than an outer piece.
Terra Incognita is a European outdoor brand with over 18 years of expedition experience and its own gear production, and the Tempo reflects that focus on function-first outdoor clothing. Seamless construction, mapped breathability zones, and a stretchy polyamide-and-elastane blend combine into a shirt that moves with you and disappears under your layers instead of fighting them.
Who is the Tempo Thermal T-Shirt for?
This shirt suits active users who work up a sweat: trail runners, cyclists, ski tourers, and fast-paced hikers who need moisture moved off the skin quickly. Because it is a base layer, it shines under a mid-layer and shell in cool weather, but the breathable knit also works on its own in milder conditions. Anyone who overheats and then gets clammy in a cotton tee is the person this is built to fix.
How does the Tempo Thermal T-Shirt compare to cotton?
Cotton soaks up sweat and holds it against your skin, leaving you cold once you slow down. The Tempo instead uses polypropylene, one of the least absorbent fibers, to push moisture outward toward your next layer where it can evaporate. Against a basic synthetic tee, the seamless multi-zone build adds targeted breathability and a chafe-free surface, which becomes obvious over long days under a pack.
How should you wear the Tempo Thermal T-Shirt?
Wear it directly against the skin with nothing underneath so the wicking fibers can do their job. Because the fabric is thin and quick to dry, it washes easily and is ready again fast, which makes it a strong choice for multi-day trips where you rinse and re-wear. Avoid heavy fabric softeners, which can coat the fibers and blunt their moisture-moving performance.

Key features
- Polypropylene fibers actively wick sweat away from the skin, so you stay dry and avoid the chill of damp fabric during hard efforts.
- A multi-zone knit places breathability and support where your body needs each, improving comfort across changing exertion levels.
- Seamless construction removes the stitched ridges that cause chafing, making it comfortable for all-day wear under a pack or harness.
- Lightweight, breathable fabric helps regulate body temperature and prevents overheating when your output spikes.
- A polyamide-and-elastane blend gives a snug yet flexible fit that stretches with movement and springs back into shape.
- Available in EU 44-48 (US S-M) sizing, it fits close as a true base layer so it can transfer moisture efficiently to your mid-layer.

Questions & answers
Tempo Thermal T-Shirt FAQ
Is the Tempo a base layer or a standalone shirt?
It is primarily a base layer meant to be worn directly against the skin under other layers. The polypropylene fibers wick sweat outward toward your mid-layer, though the breathable knit also works on its own in mild conditions.
Does it help keep you dry during exercise?
Yes, keeping you dry is its main purpose. The polypropylene fabric pulls sweat away from your skin, and the multi-zone breathable knit helps it evaporate, so you avoid the clammy, chilled feeling that damp cotton causes during hard effort.
Will the seams cause chafing under a backpack?
No, the shirt uses seamless construction specifically to prevent chafing. Without stitched ridges rubbing against your skin, it stays comfortable for all-day wear beneath a pack or climbing harness.
What sizes are available?
The Tempo is offered in EU 44-48, which corresponds to US S-M. It is cut to fit close as a true base layer, which is what lets it transfer moisture efficiently to the layers worn over it.
