You’re standing in the store reading on a glove: Thermo insulation, Thermo lining, Thermo membrane. Sounds warm. But what does it actually mean – and why do some thermal gloves really keep you warm at minus 5 degrees, while others fail already at plus 2 degrees?
This guide explains what the term thermo really means, how heat technology works in cycling gloves – and why the difference between marketing talk and real performance is significant.
What does thermo mean for gloves anyway?
Thermo is not a protected term. Any manufacturer can use it – on cheap fleece gloves just as well as on technically sophisticated multi-layer systems. This makes comparing purchases difficult.
Technically, thermo in gloves describes the ability to retain body heat and slow down heat loss to the outside. This happens through a combination of three factors:
- Insulating materials – fabrics that actively store heat
- Windproof outer layers – which prevent cold drafts from blowing away body heat
- Moisture management – which ensures that sweat does not become a source of cold
Good thermal cycling gloves master all three. Cheap models often optimize only one dimension – and fail in the other two. More about the importance of windproofing can be found in the article about windproofing in cycling.
