70/100
Well-made, but plastic on skin.
Best for Outerwear or layers — not for direct skin contact.
This product scored 70/100 on the material-quality rubric (durability, comfort, breathability, warmth, moisture-wicking, care-ease), based on its composition of 47% Merino Wool, 33% Nylon, 14% Polyester, 6% Elastane. Sustainability is scored separately as the Eco Rating. Blended from 47% Merino Wool, 33% Nylon, 14% Polyester, 6% Spandex — the score is a weighted average based on each material's proportion.
B (70-84): Good material composition — above average across most axes.
Good quality
Well-balanced fabric that should serve you well. The natural-synthetic blend offers durability with comfort. Follow the care guide to maximize lifespan.
Better-than-typical fabric, but priced above the category median.
Fabric value only — compares material quality to price vs other shorts. Construction, fit, and brand aren't measured.
47% Merino Wool, 33% Nylon, 14% Polyester, 6% Elastane
Mostly natural with stretch
Sustainability is scored separately — see the Eco Rating below.
Every wash of synthetic fabric releases up to 700,000 microplastic fibers into waterways. Use a Guppyfriend bag to catch them.
This fabric will take 200+ years to decompose. That means a shirt you buy today will still exist in the year 2226.
Dryer heat destroys spandex/elastane over time. Your leggings and stretchy clothes will last 2x longer if you skip the dryer.
Heavyweight
Indigo twill — heavy, structured
Reasonable cost-per-wear
Base for Shorts: 120 expected wears.
× 1.20 for 247 g/m² (heavyweight).
× 1.00 for Merino Wool (mid-durability fiber, durability 79).
= 144 expected wears. $138 ÷ 144 ≈ 96¢/wear.
Real life is messier than a formula: how often you wash, how you wash, whether you wear it inside-out, dry on low — all of it shifts the number. This is the ceiling under reasonable care.
