Learn how to choose the right size and care for the Disana Boiled Wool Vest, including lanolizing and washing tips to keep it soft and effective.
Quick Answer
For the Disana Boiled Wool Vest, choose your child's current size without sizing up, and care for it by hand washing in cool water with wool wash, then lanolizing to maintain its water-resistant and breathable qualities.
Why Sizing Runs Big
The Disana Boiled Wool Vest is designed with a relaxed fit for freedom of movement. The boiled wool fabric has some natural give, and the vest is meant to be worn over a base layer without being restrictive. Because it runs big, sizing up can lead to excess fabric that may bunch under outer layers or let cold air in.
Caring for Boiled Wool
Boiled wool is durable but needs gentle handling. Washing in hot water or agitating it can cause shrinkage and felting, which would ruin the vest's fit. Always use a wool-specific detergent and avoid the dryer. Lanolizing replenishes the natural oils that keep the wool water-repellent and soft.
Sizing and Care Decision Rules
- Choosing a size: Use your child's current measurements and refer to the size chart. Because the vest runs big, do not size up for growth; a snug-but-comfortable fit keeps warmth in. Measure your child's chest and compare to the chart before ordering.
- Washing method: Hand wash in cool water with a wool-safe detergent. Gently squeeze, do not wring, and lay flat to dry away from direct heat. Always test a small area for colorfastness before full washing.
- Lanolizing frequency: Lanolize the vest every few washes or when water stops beading on the surface. Dissolve a small amount of lanolin in warm water, soak the vest, then rinse in cool water. If the vest feels dry or less water-resistant, it's time to lanolize.
