Ultralight Windproof Shorts

Klettarmussen's lightest shorts for high-pulse activities. Made from ultra-lightweight Oculus ripstop fabric. While the fabric of Klettalmusen Windshell's representative Nal series is 74g/m2, this new material is extremely lightweight at 48g/m2. It's ideal for active environments such as trekking and trail running, but its lightweight and quick-drying properties make it versatile for most summer activities. Made of polyester, it is highly durable and feels dry to the touch.

The new material Ultralight Oculus ripstop is made from 100% recycled polyester. It uses an alipstop construction using 20 denier thread to minimize weight while ensuring tear strength. The result is a material that is strong, yet light and soft. This yarn is based on polyester, and its hydrophobic properties make it an extremely quick-drying material. And it's treated with Green First insect repellent to provide the protection you need during the summer. Green First is inspired by nature and uses geraniol, which is found in many plants, as an active ingredient.

Main Fabric:
Ultralight Oculus ripstop
100% Organic Cotton, 103 g/m², GOTS-certified fabric, Fluorocarbon free Katra® organic cotton is Klettalmusen's unique performance cotton material that rivals synthetic fibers. Utilizing bionic principles, a natural process, it gives cotton a distinctive lustrous appearance and properties similar to those of synthetic fibers. By subjecting cotton to pressure and heat that mimics geological compression, we create a natural fabric that is windproof, water repellent, and breathable. The addition of ripstop to the fabric significantly increases its strength and allows it to withstand heavy loads. Because it complies with high-quality ecological standards, it takes much longer to produce than regular cotton. For example, with conventional cotton, the time from fiber to fabric is approximately 55 days. However, lightweight 100% organic cotton material takes more than 85 days. In today's rapidly changing society, Klättalmusen believes that slowdown is necessary for people and the environment.

Measuring Guide

1. Chest - Wrap 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.
