FAQs

Are these bottoms suitable for skiing?

Yes, they are an excellent choice for a ski base layer as they provide warmth without adding unnecessary bulk under ski trousers.

Can I tumble dry these?

It is not recommended. Air drying is the safest method to preserve the fabric's wicking performance and the elasticity of the waistband.

What size is the UK 16?

The UK 16 size corresponds to standard adult female sizing, designed to provide a comfortable, non-restrictive fit for active use.

Do these have a thermal lining?

These bottoms rely on the thermal properties of the polyester material rather than a separate fleece lining, making them more versatile for layering.

How do the flat seams help?

Flat seams sit flush against the skin, which significantly reduces the risk of chafing during repetitive motions like walking or skiing.

Troubleshooting

Feeling damp while active

Ensure you are not wearing non-breathable outer layers over the base layer, which can trap sweat inside.

Waistband sliding down

Check that the sizing matches your measurements; base layers should be snug to prevent movement during activity.

Pros and Cons

Pros

  • Moisture-wicking fabric keeps the skin dry
  • Flat seams prevent skin irritation and chafing
  • Elasticated waistband ensures a reliable fit
  • Lightweight design makes them ideal for layering under outerwear

Cons

  • Not intended for heavy-duty outdoor wear on their own
  • Polyester material requires careful washing to prevent pilling
  • Limited to cold-weather layering use

Setup, Compatibility & Care

To maintain the integrity of the polyester fibers, wash these bottoms in cool water on a gentle cycle. Avoid using fabric softeners, as these can coat the synthetic fibers and diminish the garment's moisture-wicking capabilities. Always air dry away from direct heat sources to prevent the elastic waistband from losing its shape or elasticity. These bottoms are designed to be compatible with most standard trekking or ski trousers and fit comfortably under mid-weight outer layers.
