bestra pants

Wind protection pant

A soft, comfortable, windproof pant made for winter trail hikes and cold-weather treks. It has excellent flexibility and heat retention, so it can be worn without base layer pants. A next-generation representative model that is perfect as an all-season midlayer.

The fabric is made of two layers. The outer layer is a 2-way stretch bio-based polyamide shell with elastane for flexibility and durability. The inner layer is a quick-drying recycled biodegradable Primaloft® knit liner for warmth and breathability. The liner's loft is lowered to match your movement, and the liner extends below the knee to reduce weight and provide comfort. Additionally, it features adjustable elastic straps for a snug fit and a zippered pocket for your valuables.

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.
