Winter in New Zealand can be surprisingly chilly! From Auckland‘s damp cold to Christchurch‘s frosty mornings, thermal underwear becomes your best friend during the colder months. But do you know how to care for thermal underwear properly?
At The Laundry Lady, we see plenty of thermal garments throughout winter. This guide will teach you everything about thermal underwear care, so your base layers stay cosy and effective all season long.
Why proper thermal underwear care matters
Your thermal underwear works hard to keep you warm. These specialised garments trap air close to your skin, creating an insulating layer. However, body oils, sweat, and daily wear can reduce their effectiveness.
- Proper care ensures your thermals:
- Maintain their insulating properties
- Last longer and save you money
- Stay comfortable against your skin
- Remain odour-free
Essential tips for thermal underwear washing
Check the care label first
Before washing thermal underwear, always read the care instructions. Different materials require different approaches:
- Merino wool thermals: Need gentle, cold water washing
- Synthetic blends: Can handle slightly warmer temperatures
- Silk thermals: Require delicate care and special detergents
Water temperature matters
Most thermal underwear responds best to cold water washing. Hot water can damage fibres and reduce the garment’s ability to regulate temperature. Cold water also prevents shrinkage, especially important for fitted base layers.
Choose the right laundry liquid
Skip harsh detergents and fabric softeners when washing thermal underwear. These products can coat the fibres and reduce breathability. Instead, use gentle, enzyme-free detergents.
Drying your thermal underwear
It’s not recommended to put thermal underwear in the tumble dryer. High heat can damage the fibres and can cause shrinkage. Instead, if possible:
1. Gently squeeze out excess water (don’t wring)
2. Lay flat on a clean towel
3. Air dry. Be careful with direct heat or sunlight
This process preserves the fabric’s elasticity and insulating properties.
Storage tips for off-season care
When Hamilton’s winter ends and spring arrives, proper storage keeps your thermals ready for next year:
- Clean thoroughly before storage
- Store in breathable cotton bags
- Add cedar blocks to prevent moths
- Avoid plastic bags that trap moisture
Common mistakes to avoid
Many people make these thermal underwear care mistakes:
- Using fabric softener: This coats fibres and reduces performance
- Washing too frequently: Over-washing breaks down fibres faster
- Using hot water: Heat damages the fabric structure
- Hanging by the shoulders: This stretches the garment out of shape
