    Light as a feather

    • Familiarity: I've used it several times

    • Size Bought: Medium

    This jacket was awesome for a hike up Wheeler Peak in Great Basin National Park in Nevada. With temps around 57 degrees at the start (at ~10,000 ft), I definitely was glad to have this in my pack once we got halfway to the peak, as the wind kicked up this kept me warm without overheating on the steeps as we got up to the summit. This jacket weighs next to nothing and balls up into the size of a lacrosse ball, making it great to stuff in a daypack (I actually keep it in my mountain biking pack in case it rains or I get a bit chilly). Norrona consistently makes high quality product and this is no exception, and the blue color is awesome too!

    30 degrees at the summit with 30mph winds? No problem! To be fair I had a down midlayer underneath but the Bitihorn over the top made a significant difference in temperature when I got to the top and caught my breath. Nothing worse than being in a beautiful place and not able to appreciate the beauty because you're uncomfortable. The Biti definitely helped. Even when the sun went down and temps dipped a bit more I was plenty cozy for the trek back down. 5/5, do recommend.


    Finally rained!

    Got this piece a couple weeks ago and have been itching to test the material in the elements. Well, it finally rained Saturday and I made sure to put it to the test. Cruised my bar bike home from my favorite burger joint and was still dry when I got in. So, I decided to go run around the park for a while. After more than an hour in steady-to-heavy rain my skin and tshirt were still dry, which is a testament to both the waterproofing and breathability. If there's one critique I'd ditch the pit-zips. The material is thin enough that you're certainly not going to be overheating with just a thin baselayer.

    Also holds up well against wind if there's no precipitation to fend off.

    Finally rained!

    Great packable shell!

    Norrona hIt the nail on the head with this jacket as it is so lightweight, and does a great job keeping you dry. I have been testing this the last few weeks biking, and late season touring in it and have nothing but great things to talk about. First off it has a really nice fit for my body type (tall, skinny). On the business end this is a super breathable, and waterproof jacket. My only issue is the waterproof rating on this may be a little inflated but for a jacket this light i would expect this. Overall its a great piece that i would highly recommend to anyone looking for a packable shell. I would have gone with the large if i could go back as the medium is a tad short.

    Great packable shell!

    Great lightweight shell

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: XL

    I've used this jacket for a couple seasons and it's a great lightweight shell to have in your bag. Fortunately, living in Utah we don't get a whole lot of real downpour kind of weather. This jacket is great to have on hand for the occasional storm. It's incredibly light weight and packs down very small. I really like how easy it is stash in my pack for a day hike or a short backpacking trip. I always like to have a shell with me in the mountains, but I hate carrying a heavier jacket in nice weather for the "just in case" sort of gear.

    I've found this jacket to be plenty waterproof and windproof for my uses. It fits true to size but it's a slimmer fit. I'm 6'1, 220# and generally either a large or an XL and I went with the XL in this jacket. I can squeeze a lightweight puffy underneath, but it's a snug fit.

    Since this jacket is so lightweight, I would hesitate to call it great for consistent heavy use. I haven't had any issues with the durability, but I also don't put it through a lot of abuse since the backpacking season in Utah generally features dry weather. If you're planning on doing a lot of hiking/backpacking/climbing in foul weather I would look for a heavier jacket with more room for layering and more protection. If you're looking for a lightweight, minimalist shell to have in your pack as a precaution, it's hard to beat this jacket.

    • Fit: True to size

    Wore this jacket in Canada, knowing that 1/5 days it was going to rain. It rained all right... Just in the afternoon/evening. I was soaked. My down jacket underneath was soaked. I know this is made to be a lightweight shell, but at rating of "20,000" I was expecting to not have to worry. I also somehow ripped the velcro tab to tighten the cuff.

    The pro's though: This jacket is SO light and the material is soft and feels good to wear with or without a mid-layer. its great if your expecting lighter rain and need something really light weight. I'm 5'9", 150lbs and fit a small perfectly.

    My new go to brand

    • Familiarity: I've used it several times
    • Fit: True to size

    This is now my go to rain jacket, super lightweight and the best fit I have ever experienced. I am usually a L in the US being tall and lanky. This European sizing fit a M perfect. Awesome arm length. Also the best hood of anything I have worn. Close on the head with a tight brim and easy adjustment. I'm definitely buying more Norr�na I'm the future.

    Wicked sweet and all that!

    • Familiarity: I've put it through the wringer

    Every person needs at least 6 jackets: down parka, heavy duty ski shell, ultralight windbreaker, a nice synthetic for cool mornings and around town, a cool soft-shell just because, and a great light windproof, breathable, waterproof jacket for all-weather running and other all-weather aerobic activities.

    The bitihorn Dri1 is just about the perfect lightweight all weather jacket for running. At 7.5 oz it may not be considered an "ultra-light" but it is very light, takes up little space, and gives the protection you need in a massive downpour or running all day in a snowstorm. It's great for running and the perfect shell for backpacking. It's just substantial enough to make you feel like you have something that will hold up to good use in nasty conditions. I've have experience in all conditions and this jacket gets it right! The hood tightens with an elastic drawstring from the back. I find it works best with a brimmed hat underneath. It has two massive pit zips to dump extra heat - very nice. I find this material better breathing and more water resistant than gore tex. There's no science behind that, just my gut feel after experience with both. This was the first Norrona product I ever bought, and started my love affair with this brand. 5 stars for being a waterproof, windproof, breathable jacket that rocks the trails.

    Awesome and versatile

    I've used this jacket for several applications. I used it for skiing, alpine and XC in New Mexico, cycling, hiking, and as a general use rain jacket around town. It has performed beyond expectations. The Dri1 material is extremely lightweight and it seems to me like it vents moisture better than the gore-tex. It vents well and I usually pair it with the /29 warm1 fleece and a good base layer. I has kept me warm and dry every time I needed it. While the price might be steep, I've gotten every penny's worth.

    Is it helmet compatible?
