The care routine for a merino and lyocell blend is simpler than most people expect, and it matches the routine for the rest of your natural-fiber wardrobe. Here is the whole thing in one line: machine wash cold on gentle, hang dry, never tumble. The rest of this guide covers the why, the details, and the mistakes that actually ruin wool garments.
The routine
- Turn the shirt inside out. This protects the fabric face from friction in the drum.
- Machine wash cold on the gentle cycle. Use a mild detergent and wash with like colors. No special wool cycle required, though it does not hurt.
- Skip fabric softener. Softener coats the fibers and blunts merino's natural moisture and odor management. The fabric is already soft; let it work.
- Hang dry. Lay flat or hang. A merino blend dries fast on its own, usually overnight.
- Never tumble dry. Heat is the one thing that genuinely damages wool. A hot dryer can felt and shrink wool fibers in a single cycle.
That is the same routine we print on every product page in the Kane Merino Collection, and it matches the care instructions for our bamboo pieces. One routine for your whole Kane drawer.
Wash less than you think
Here is the part that saves real time: merino does not need washing after every wear. The fiber neutralizes odor on its own, so a shirt worn for a normal day is usually fine to air out overnight and wear again. Hikers wear merino for a week straight for this exact reason. Washing less also means less fiber wear, which extends the life of the shirt. When in doubt, use the smell test; merino will tell you honestly.
What to avoid
- Heat, in every form. Hot water, hot dryers, and high irons are the only real threats. If you must iron, use low heat.
- Bleach. Never. It attacks the protein structure of the wool.
- Fabric softener. Redundant and counterproductive, as above.
- Wringing. Squeeze water out gently rather than twisting the garment.
Storage
Fold rather than hang for long-term storage; long hanging can stretch shoulders in any knit. Make sure the shirt is fully dry before it goes in the drawer. For seasonal storage, clean the garment first, since moths are drawn to worn wool, not clean wool.
Frequently asked questions
Can I machine wash a merino TENCEL shirt? Yes. Cold water on a gentle cycle is exactly what our blend is designed for. Hand washing is fine but not required.
Will merino shrink? Not if you keep it away from heat. Cold wash and hang dry cause no meaningful shrinkage. A hot dryer can shrink and felt wool in one cycle.
How often should I wash it? Less often than a cotton or polyester shirt. Air it out between wears and wash when it needs it. Our post on merino wool vs polyester explains why merino stays fresh so much longer.
Is the routine different for Kane's bamboo shirts? No. Cold wash, hang dry, no bleach, applies to everything we make, which keeps laundry day simple.
