Technical specs
Materials & design
Soft cotton
The soft dark grey fabric is kind to your skin and breathes, so the T-shirt stays comfortable and never stuffy all day. It is casual cotton, not a technical layer.
Durable graphic print
The fish-themed print is durable and keeps its brightness when cared for properly, so the fishing motif does not fade after the first washes.
Versatile style
The dark grey colour and understated graphic design suit both the city and the outdoors, so the T-shirt is comfortable every day, also as a layer under a jacket or hoodie.
How it differs from cheap T-shirts
Care
Wash inside out and cool on a gentle setting, without bleach. Do not iron the print directly: iron inside out or work around the design. Dry naturally, so the fabric and the fish print last longer.

Membrane waterproofing and breathability
Membrane fabric is usually described using two numbers, often separated by a slash: waterproofness and breathability. The first number indicates waterproofness, the second indicates breathability.
?Waterproofing
This is a sliding scale measured in mm that shows how high a column of water you can suspend over the membrane before it starts to let moisture through.
Waterproof Rating Conditions 0–10,000 mm Light rain, dry snow, light pressure. 11,000–15,000 mm Moderate rain, average snow, light pressure. 16,000–20,000 mm Heavy rain, wet snow, some pressure. 20,000 mm+ Heavy rain, wet snow, high pressure. ?Breathability
This is the amount of moisture by weight that can pass through one square metre of fabric over a period of 24 hours. It is commonly measured in g/m²/24 hrs.
Breathability Rating Level of Breathability 0–5,000 g/m²/24 hrs Low – light exercise. 5,000–15,000 g/m²/24 hrs Medium – medium to high energy activity. 15,000 g/m²/24 hrs+ High – vigorous sustained activity.
