What would “lasting” mean for this shirt?
A tee may remain wearable as an underlayer after it no longer looks right for work. A small repair may extend its usefulness, while a changed neckline may bother you enough to retire it from public wear. Decide which standard matters before comparing anecdotes about how long shirts last.
Frequency alone is also incomplete. Ten wears can mean ten short evenings or ten full outdoor days. When reading a review, look for the use described, not just the ownership date. A report with no information about wear, washing or damage location gives little basis for predicting your own result.
Match the construction to repeated contact
REI notes that heavy pack straps can abrade wool worn as a standalone top. That makes the contact points worth examining when the shirt is intended for hiking. See REI's material comparison.
Inspect the pack or other equipment at the same time: a rough fastener, a gritty strap or a sharp edge is not a shirt specification problem. A shirt sold with reinforcement may be worth comparing, but first identify what it will be rubbing against. Our nylon-blend guide explains one construction choice without assigning it an invented lifetime.
Compare hiking shirts for that workload rather than using the age of a lightly worn office tee as the expected lifespan.
Distinguish wearability from a new-looking surface
Record whether the problem is cosmetic, structural or localized to a seam. A few surface pills, a thinning patch and a seam that has opened are different endpoints; reports that call all three “worn out” are difficult to compare.
For the detailed investigation, use pilling, holes or repair options. Those pages handle the particular fault. For lifespan, the useful question is when the shirt stopped serving your intended role and whether a repair restored it.
Keep useful evidence from the first sign of trouble
Photograph the area while it is small, note the model and approximate use, and retain the care instructions. Those details help the maker respond to a warranty or care question. A clear description is more useful than saying the shirt did not last long.
How many years should a merino shirt last?
There is no universal number. Use, construction, care and your standard for acceptable appearance vary too much to predict years from fibre content alone.
Does pilling mean a merino shirt is worn out?
Not necessarily. Pilling concerns the surface and needs a different assessment from thinning fabric, open seams or holes. Evaluate the actual condition before deciding to replace it.
