Activity Base Layer Tee

A technical base layer made from natural fibers, perfect for intense activities on warm spring days or as a first layer when skiing or climbing. The blend of organic merino wool, Tencel® and wool also makes it resistant to abrasion and tear.

Klettalmusen backpacks are made from fishing nets (used aquaculture and ghost fishing nets), fluff (used nylon carpet tops), plastic industrial waste, and scraps of thread and fabric.

Tencel is the brand name for a fiber called lyocell, which is more absorbent than cotton, softer than silk, and cooler than linen. The advantage of using Tencel next to your skin is that it has a natural antibacterial effect that prevents moisture from forming on the fibers by transporting moisture inside the fibers. Tencel is a recycled fiber made by melting wood pulp. Although it is a cellulose fiber like viscose, it uses an environmentally friendly manufacturing process. TENCEL uses less energy and water, uses no chlorine, produces minimal waste, and is considered non-hazardous. At the end of its lifespan, Tencel products can be recycled and, since they are made from cellulose fibers, they are also biodegradable.

Measuring Guide

1. Chest Place the measuring tape under your arms and around the widest part of your chest. Take a deep breath and check to see if the tape measure is too tight.

2. Waist Place the measuring tape around your waist at the smallest point around your navel, relax deeply and take a deep breath to make sure the measuring tape is not placed too tightly .

3. Sleeve Length - Find the highest point of your neck with your fingers and start from there and place the measuring tape. Next, place the tape measure along your shoulders and lower it down your arms. Bend your arm slightly and place the tape measure on your elbow, then lower it to the vertebrae of your wrist and measure.

4. Back Length - Use your fingers to find the highest point of your neck, start from there and measure to the same point you used to measure your waist. Tip: Wrap a webbing belt around your waist as a guide so you know exactly how far down you should measure.

5. Seat - Wrap the measuring tape around the widest part of your buttocks. At this time, be careful not to make the tape too tight.

6. Inseam - Place the tape measure between your crotch area and measure from there to the inside of your foot at the ankle.
