FAQs
What temperature range are these best for?
These are ideal for temperatures between 8 and 20 degrees Celsius.
Are these warmers windproof?
No, they are made from high-stretch fleece and do not contain wind-blocking membranes.
Can I wash these in a machine?
Yes, machine wash on a gentle cycle, preferably using a garment bag to protect the grippers.
Are they gender-specific?
The Thermoflex 2 warmers are designed as a unisex product.
Do they provide UV protection?
While not specifically marketed as sun-blocking sleeves, the fabric provides a physical barrier against direct sunlight.
Troubleshooting
Warmers sliding down during a ride
Ensure the silicone gripper is in direct contact with your skin rather than over jersey fabric, and verify that the area is free of lotions or oils.
Fabric bunching at the elbow
Smooth the fabric out fully after pulling them up; the single-piece construction is designed to conform to the arm once properly positioned.
Pros and Cons
Pros
- High-stretch material allows for unrestricted movement
- Soft, comfortable fleece interior against the skin
- Reliable silicone grippers prevent sliding
- Easy to stow in a jersey pocket when temperatures rise
- Durable, single-piece construction
Cons
- Not waterproof or windproof
- Performance is limited to dry conditions
- Lightweight material may not be sufficient for extreme sub-zero weather
Setup, Compatibility & Care
To ensure the best performance, wear these warmers under the sleeve of your short-sleeve jersey. The silicone gripper should be positioned directly against the skin at the bicep to maximize grip.
Care instructions are straightforward: machine wash at a low temperature, ideally using a mesh laundry bag to protect the silicone grippers from snagging on other items. Avoid using fabric softeners, as they can degrade the technical properties of the fleece material. Air dry the warmers in a shaded area to maintain the integrity of the fabric's elasticity.
