Why We Like The Treeline Rain Shell

With the Treeline Rain Shell clipped to our pack, we're ready for nature's surprise tantrums. When the first fat raindrop splats our cheek and the wind starts to howl, we quickly shrug into the watertight jacket and cinch the hood tight just as the sky dumps. The pack-friendly hand pockets keep our snacks and topo dry, while the adventure-ready design moves with us as we push onward through the sideways torrent.

Perfect lightweight rain jacket

I've used it several times
Size Bought:
5' 8"

I was looking for a lightweight jacket that I could travel with and layer over warmer clothes and this is the trick!

best light weight rain jacket

This rain jacket is seriously my favorite fall item! Great for layering under the coat. Repels water so well while still being ver durable. I have a dog who loves to rough play with some sharp teeth and nails. This jacket has withstood 3 years so far and I expect many more! Couldn’t recommend this more.

Lightweight, great fit, comfortable and stays dry even through long downpours. Great for backpacking and long treks in the backcountry.

Solid jacket

Lightweight and durable. My only complaint is that, while the hood is great for accommodating helmets and ponytails, there is not an adjustment for when you want to wear the hood without a helmet. You can tighten the opening, but I would love to also be able to pull the hood back and Velcro it so that my hoodie doesn't cover up my eyes when in use. Granted I have a smaller than average head, but I imagine this would still be an issue with people with average sized heads.

Great piece

Outdoors in the Pacific NW inevitably involves rain. I find this jacket very water proof whether hiking in the mountains or walking around the neighborhood. It's a good outer layer on soggy days, and very packable. A great piece of gear, that can be appreciated by novice and expert alike. Highly functional and beautiful too! Whether headed for a summer hike, or winter xc-skiing, pack this a long as a waterproof top layer (or single layer).
