In the outdoor industry, fleece is often marketed for their technical properties, including their ability to trap warm air, draw away cold air, and provide breathability. However, it is important to note that some of these claims are exaggerated or misleading in practice.

Polartec Alpha has truly unrivaled functionality as a stand-alone fleece. Its unique characteristics of an open knit lattice with lofted fibers delivers unparalleled an warmth-to-weight ratio while keeping bulk and weight to an absolute minimum. The open knit lattice provides the freedom to move effortlessly and unrestricted, and allows for effective heat/moisture transfer. Polartec Alpha truly sets the new standard for an active insulation fleece midlayer.

These fleeces have undergone extensive testing over thousands of miles on the trail, with hikers speaking highly of their performance and durability. The collective experience and positive feedback should offer insight into the minimal drawbacks of its ultralight construction.

As with any outdoor apparel, it's important to consider the pros and cons when choosing the right gear. Polartec Alpha offers significant advantages, but it also highlights the importance of taking care of your gear.

Due to the emphasis on breathability, the fabric has reduced wind resistance compared to a thicker, bulkier fleece. This can be an advantage or a disadvantage depending on the situation. In adverse weather conditions, the user would be relying more on a dedicated wind/rain layer for optimal protection and insulation. That being said, if the wind isn't getting in, your body heat isn't getting out!

While Polartec Alpha holds up reasonably well to general abrasion, it's important to be cautious of potential punctures and runs in the knit lattice when exposed to sharp objects or rough surfaces. Luckily, we do in house repairs for most small holes/runs that occur during its lifespan. Don't hesitate to reach out if you have any issues.

By understanding these characteristics, users can maximize the benefits while taking appropriate measures to ensure its longevity and performance.

Extend the lifetime of your garment by washing it infrequently, and always storing and washing it inside of your Senchi Bag.
Machine wash cold, delicate cycle, tumble dry low or lay flat to dry.
Do not bleach, dry-clean, iron, use fabric softener, or machine-wash with agitator (unless it's in the mesh bag)

Synthetic apparel is made from petroleum products. It provides excellent breathability, and has a low water absorption rate, meaning it retains less moisture compared to natural fibers.

However, one of the concerning aspects of synthetic clothing is the shedding of microplastic fibers during the wash and wear process. These tiny fibers are released into the water column and can accumulate in marine environments, posing potential harm to aquatic ecosystems.

The Senchi Bag is specifically designed to mitigate the release of plastic fibers. While it is not a comprehensive solution to the problem of microplastics, it serves as a proactive measure to minimize impact.

Transparency, accountability, and continuous improvement are at the core of our values. We are dedicated to developing high-performance outdoor apparel, but also actively advocating for positive change within the fabric industry and the development of bio-based, high-performance fabrics.

While it is a really great piece of gear, there is value in appreciating and fully utilizing your existing equipment. Gear should enhance, but not define, your adventures.
