Essential and Versatile Piece of Gear

I rarely leave home without this jacket come springtime in the Rockies. It is hard to find clothes that work well for day-long activities but this piece excels. It keeps you warm and dry in driving rain while fitting well and is incredibly lightweight. Additionally, the jacket has taken a beating in several mountain bike crashes with little signs of wear. This jacket should be in every adventurer's wardrobe.


This is a wonderful piece. Super useful, great weather resistance, ultra packable and lightweight. I use this for multipitch climbing, and it has held up surprisingly well for how paper-thin the fabric is. It is a really versatile and useful jacket. When it dies I will definitely pick up a new one. I really wish for an attachment loop in the stuff pocket so that it could be clipped to a harness - the one thing that holds this jacket back from perfection, in my eyes.

Fantastic multi purpose hoodie

I've worn this hoodie from the day it arrived (ahead of schedule, by the way). It's perfect for a hike with the pooch, the plane, or working from home. Had no idea I'd be wearing this every day!

Best Hiking Jacket Ever

I just completed the 20 Mile Enchantment hike in Washington. This jacket saved me. It was very cool at 5am when we started and when it warmed up this jackets folds so incredible small that i can throw it in my day pack without even noticing its there. When we got to the summit, the wind was serious and I was shocked how well the jacket worked as a wind breaker. It saved me for the third time in the evening when it started to get real buggy on the trail and I was able to wear the long sleeve and the hood with out getting hot. Amazing Jacket! Will come with me on every hike for sure!

Perfect Lightweight Rainwear

I love this jacket. It's feather-light, water beads right off of it and it breathes. Amazing quality construction, fabric and zippers. One of the most advanced technical pieces I own. Ultra-portable it packs down to nothing; I keep it in my backpack. Customer service was also fantastic as I ordered a size too small and they swapped it out right away with no issues.
