    Never Leave Without It

    • Size Bought: Large

    This jacket among my favorite pieces of gear we sell. I like it so much I snag one for my friends to use all the time. I don't always end up using on my trips, but at 5.8 ounces, it's always in my pack. Its saved me from thunderstorm in the desert, sleet and snow in the mountains, and gusty winds at the top of peaks. Its such a good piece of gear that I grab an extra for my friends in case they don't have one.



    Probably because I only use it in inclement weather, I don't have a picture of me wearing it, but here's one of a buddy who used the men's version for some wind protection recently.

    Never Leave Without It

    The Gold Standard

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Large

    Got to test this for a day of scrambling on American Fork Twins in Utah in August--you cannot ask for a better ultralight emergency shell/wind jacket/primary shell in warm weather. On the day I tested I was working hard on the uphill in ~70deg temps and never felt overheated. The summit brought HIGH winds as soon as we topped out and the Helium withstood it no problem. I'd have confidence bringing this jacket as a primary packable shell for backpacking, mountain biking, day hikes in all but the coldest temps. SUPER versatile layer!

    Lightweight weather proofing

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: Large

    I used this jacket on the PCT this year and it does its job as intended. this year was a high moisture year for the Pacific Crest Trail and this jacket kept me dry through it all. I bought this jacket a couple of months before I left for my trip and got some testing in before it went with me so I knew it worked. But after putting on 1000+ miles on the jacket I've got an even better idea of how well it works. It isn't the most breathable jacket on the market but for the price and weight its a fantastic option. While going through the dessert section of California I experienced high winds, rain, and snow which was unusual for southern California. And I was very glad I went with the helium instead of just a windbreaker like many others on the trail does. After 600 of miles of hiking through the desert with a couple of small rainstorms I really got to but this thing to the test as we got rained on and snowed on for 5 days straight with high winds and overall miserable conditions, but this jacket kept me dry and relatively warm by keeping the wind at bay. The Jacket has put up with the beating of a thru-hike and is still in great condition. It's my go-to jacket for all of my backpacking trips where the forecast isn't looking great, and it's so light that I keep it with me on trips where the weather is supposed to be great as most people who spend lots of time in the mountains can tell you the forecast isn't always accurate. With how light this jacket is at only 6.5 ounces theres no reason to not bring it on fair-weather trips as an extra layer if it gets chilly or the wind picks up. All in all its a great layer that is Water and windproof that you can count on. When this one wears out ( which probably won't be for a while) I'll definitely be getting a new one.

    If you're like me, you might get tired of following the boy scout motto to "be prepared" from time to time--especially for quick trips. Then you caught in a desert T-storm miles away from your car, pull this bad boy from the depths of your pack, and thank your annoyingly responsible self for having purchased, and packed, the Helium II. Light and compact, its the perfect backup plan.

    Great review, Matt! Many thanks and Happy Trails!

    The Helium II is very ultralight. It can easily be taken on any adventure due to its tiny pack size. This jacket blocks rain and wind well. The elastic cuffs and the drawcord on the hood will ensure that you stay dry in a rainstorm. The jacket was made to be very low profile weighing only 6.4 ounces. There is only one pocket in the chest to stash your phone, wallet, and keys. I am 6'0 175 lbs and a large fits me well. It is more of a slim fit, if I wanted to layer a lot, I would go with an XL. I would recommend this jacket to anyone that likes to travel light because they can always store this in their daypack just in case the weather changes in a hurry. If you want something with more pockets or something a little bit thicker, I would recommend going with the Outdoor Research Guardian or the Interstellar.

      If you plan to wear this over a down vest beware. You will be wise to size up. The return shipping is on you! For that reason, I will be reordering from REI.

      Sorry about that Douglas. It might depend on the body... I layer with mine ok, but know that everyone might not be able to.

      The "Oh Crap" Jacket

      • Familiarity: I've used it several times
      • Size Bought: Medium

      No frills, minimal features, but it has kept me dry in a couple unexpected downpours and some major rainstorms! It's not breathable so expect some humidity to build up. It's a sacrifice of breath ability for weight. I've used it hiking, backpacking, camping, and climbing. It packs into its own pocket (about the size of a baseball), and although I wouldn't recommend this method - the whole thing packs into my pants pocket easily and comfortably too. Wind and rain resistant as it gets and for only (I cannot stress this enough) 6 oz! A wonderful insurance policy.



      The first couple times I wore it, I kept reaching to put my hands in the jacket pockets only to find none were there. There is one pocket on the chest which I found odd.



      The hood's nice and adjustable too. There's a draw cord on the hood and on the bottom. At 6 oz (yessss) there's no reason for me to not keep this jacket in my pack.



      The Medium and the Small also fit me well. Guess I'm right in between - just depends on if you want to have more layers underneath (I stuck with the medium).

      Just in case

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

      This is a great lightweight piece to throw in your pack if there's a chance of rain, but you don't want to waste the space or weight bringing your burly rain gear. I found it to be great for spring bike commuting and around town use. This would be a great emergency rain shell for those of us in the generally dry western ranges that often have afternoon thunderstorms and rain showers. I did find myself wishing it was an inch or two longer, but I'm relatively tall and wear a medium, so this won't be an issue for many folks.

      Thank you for the review, Dana!

      Got this for the PCT

      • Familiarity: I've used it several times
      • Fit: Runs small
      • Size Bought: Large

      Am looking forward to putting some serious miles on this jacket, Tested it a few times and the water-proofing is sweet, breathability is sub-par but for the weight of this thing, I can't complain at all. Will update this review after 2652+ miles along the Pacific Crest Trail. It does run a little small so I sized up so I can layer and have the sleeves fit my monkey arms. But as of now, I love this jacket.

      Good luck on your adventure!

      • Size Bought: L

      Used this jacket for a weekend filming a bike race in Comfort, Texas. It turned out to be perfect testing conditions for this piece. Very high winds and gusts on Day 1 and light rain in the evenings. This ended up being the PERFECT piece--highly breathable for carrying around my 40lb+ pack on singletrack, it is crazy lightweight and doesn't feel muggy in warmer weather. Also crazy packable when i needed to stash it. This jacket definitely made my wishlist as the perfect emergency layer for backpacking, and even a great everyday rain jacket since it's waterproof unlike some other "water resistant" layers in this category.

      Great review - Alex. Thank you so much!

        Bad zipper

        The downfall of this jacket is the zipper. Since I got the jacket the zipper has always been tough to use. I took it off the other day and the zipper guide came off and is stuck in the zipper mechanism.

          Essential in Seattle

          • Familiarity: I gave it as a gift but have feedback to share
          • Fit: True to size
          • Size Bought: Large

          I got this for my dad as a birthday gift. He lives in Seattle, and the stereotype is true, it rains a lot. My dad told me he was in need of a rain jacket and that he also needed a new Patagonia Houdini (which is not waterproof). With this jacket I was able to get him everything he wanted in one jacket! This jacket also functions as a Houdini, meaning it can conveniently fold into its own pocket. So far my dad had been super satisfied and is staying dry in the rainy Seattle fall.

          Seam Tore On First Day Of My Trip

          • Familiarity: I've used it once or twice and have initial impressions
          • Fit: True to size
          • Size Bought: Medium

          I had high hopes for this jacket from all the great review. I needed something light to for my recent trip of the high sierra route. I am so lucky it didnt rain the whole trip because the pit seam was torn on the first day before when I went to put it on. Luckily I was able to patch it and make it usable for the rest of the trip. It kept me extra warm over my down and on chilly mornings but because of the durability, its going back.

          Lightweight and Does the Job

            What more can you ask from a packable rain jacket! Keeps you dry, is super light to stuff in a pack, and looks great!

            The best

              By far the best light weight water proof jacket. I use this jacket for mountain biking for those days when you get caught in a down you and it is amazing. Super light weight and stuffs super small in its own pocket.

              Light weight, packable, and water proof!

              What else do you want in a jacket? well maybe arm-pit vents but for me, this is more of an emergency shell I take for day hikes and climbs. The taped seams means you'll be staying dry when the weather isn't on your side.

              How to Measure:
              For best results, take measurements over your underwear.
              Chest:
              Measure under your arms, around the fullest part of your chest.
              Waist:
              Measure around your natural waistline, keeping the tape a bit loose.
              Hip:
              Measure around the fullest part of your body at the top of your legs.
              Inseam:
              Using pants that fit well, measure the crotch seam to the bottom of the leg.
