Product Information

Full details

The Mountain Warehouse Keep The Heat IsoTherm Top is designed for active women seeking a lightweight yet effective base layer for cold-weather activities. Its primary benefit is the IsoTherm technology, which retains body heat without the bulk associated with traditional thermal wear, though users should note it is a slim-fitting technical garment primarily intended for layering. This top is an excellent choice for hikers, travelers, and anyone needing moisture-wicking comfort during winter months.

Extended Product Information

FAQs

Is this top suitable for freezing temperatures?

Yes, it is designed to be an effective base layer in cold conditions, especially when paired with a mid-layer and a jacket.

Can I put this in the tumble dryer?

While it dries quickly, we recommend air drying to extend the life of the technical fibers.

How do I know which size to choose?

The top is designed for a performance fit; refer to the sizing chart based on your dress size to ensure it is snug but comfortable.

What is the warranty period?

The product includes a 2-year warranty against manufacturing defects.

Does it have a specific neckline style?

Many of the variants feature a crew neck design, offering a classic look suitable for layering.

Is it bulky under other clothes?

No, the IsoTherm technology is specifically designed to provide warmth without the bulk of traditional thermal layers.

Troubleshooting

Garment feels damp after heavy exercise

Ensure you are not wearing non-breathable outer layers over the top, which can trap moisture inside.

Fabric feels less effective at wicking

Wash the garment to remove soap residue or body oils that may have built up in the fibers; avoid fabric conditioners.

Pros and Cons

Pros

  • Retains warmth effectively without bulk
  • Excellent moisture-wicking capabilities
  • Extremely lightweight and packable

Setup, Compatibility & Care

To ensure your IsoTherm top retains its technical properties, follow these care instructions:

  1. Washing: Machine wash on a gentle cycle using mild detergent. Avoid using fabric softeners, as these can coat the fibers and interfere with the moisture-wicking technology.
  2. Drying: Air drying is recommended to maintain the integrity of the fibers, though the quick-dry nature of the fabric ensures it will dry rapidly even without a tumble dryer.
  3. Compatibility: This top pairs perfectly with other Mountain Warehouse mid-layers and waterproof outer shells. Because it is designed to be close-fitting, verify your size to ensure optimal heat retention without feeling constricted.
  4. Warranty: Keep your purchase receipt safe to utilize the 2-year quality guarantee if you encounter any manufacturing defects.
