The Arc'teryx Women's Beta SL Jacket is the ultimate companion for gram-counting backpackers, hikers, and trekkers who demand exceptional weather protection in a minimalist package. Built with an innovative PFC-free GORE-TEX ePE membrane, this jacket sets the standard for lightweight, breathable shells. The GORE-TEX C-KNIT backer technology keeps you comfortable on the move, while maintaining exceptional breathability. Made with a bio-based nylon face fabric derived from plants, the Beta SL Jacket reduces environmental impact. Plus the PFC-free construction eliminates harmful chemicals without sacrificing performance.

GORE-TEX ePEis a totally PFC free waterproof membrane designed by Gore to be more sustainable and cut out harmful long chain 'forever chemicals' found in normal PTFE waterproof membranes. The ePE membrane is a thinner than standard GORE-TEX and GORE-TEX PRO, which results in a softer and more supple feel. It doesn't have the same stiff 'cardboardy' feel as older Gore membranes. The biggest performance difference you are most likely to notice is the DWR treatment. Unfortunately flurocarbons are some of the best, most hydrophobic chemicals out there. Getting rid of them does hit performance so you will notice that the nice 'beading' effect disappears quite quickly. Don't worry your GORE-TEX ePE jacket is still waterproof, but to maintain the beading effect you will need to top up the DWR more regularly

Articulated patterning allows for unrestricted mobility during dynamic activities. The helmet-compatible StormHood delivers full coverage without compromising visibility, keeping you focused on the trail ahead. A RECCO reflector enhances your safety in case of emergencies.
