    My favorite running vest by far. I use it for ultra running to even day hikes, is extremely well balanced especially when you put small bottles in the front pockets which I use for anything from cell phone to my gels and bars. You can squeeze insulation and a rain jacket in the rear bladder compartment too. Looking forward on the 3.0 coming out soon.

    Very happy with my alpha 2.0. Plenty of room for all of my goodies and must haves. The fit is outstanding and the on the go adjusting straps work flawlessly. Excellent customer service as well!

    Great vest, very comfortable. I ran 15 miles with it the first day, and had no chafing or discomfort. I really like the elastic chest closures, which make it very secure without limiting breathing. The full bladder rides well, and I can still strap a rain jacket on top of it. My only complaints are that the little shoulder pockets are too small to really be useful, the hydration hose clip isn’t very secure, and I don’t personally care for the “big bore” hose mouth piece / valve. No deal breakers though, great vest! I’m a skinny 5′ 9″ and the medium recommended by the size chart fits me well. Also, the shipping direct from Ultraspire was super fast.

    The vest is great, absolutely love it! Nice fit, comfortable and secure.The bite tube is terrible, absolutely hate it! Very difficult to open , equally difficult to close. If I’m missing something, let me know. Plan to ditch the bladder, but again, I can’t fault the vest at all!

    Great product, great Service ! After some trouble with sizing, I was allowed to exchange the vest, even though I’d worn it for a few runs. I wore the new vest for a 100 km race and it was very light, comfortable, and practical. I recommend using it with 2 flasks in the front pockets and using the bladder area for extra storage.

    The sizing chart is questionable. I am a lean 155 pounds 5-8” male with a 38” to 40” chest (emptied of air vs full of air), and the large is considerably loose around my rib cage and especially my waist. It seemed alright when I tried it on, but after running in it with water bottles in the front pockets, I realized it wasn’t a good fit. It would have been nice to have some adjustment straps on the sides, but I’ll have to settle for clothes pins because my race is coming up fast and it’s the only pack I’ve got for practice… Other than that, I love the vest ; very comfortable, looks great, very practical. I bought some Ultraspire flasks to put in the front pockets and I love them ; they work very well with the vest and they don’t rub against my ribs like round bottles would.

    I am a female marathoner average weight with very broad shoulders. I initially tried the Astral and it dug into my collarbone, clearly designed for a more traditional female physique. I figured I would give the Alpha a try. I love it! I have used many other brands and am amazed at how light this pack is. Yet it is still able to hold everything that I need for a full marathon. My skins becomes very irritated very easily, which is why I was searching for a new pack…traditional packs cause jacket zippers to tear my skin along my sternum, regardless of how much Glide I applied. The elastic on the front of this pack eliminates this issue so that I run in comfort. I highly recommend it!

    I have the Alpha 01 vest and I absolutely love it! It sits comfortably and doesn’t shift around during my run! I started using it for shorter runs too instead of a waist belt. Couldn’t be happier. I keep telling everyone this is the running vest you want!!

    After trying on packs from several other well loved brands, I had been disappointed with the fit and cost. I came across AltraSpire and bought the Alpha 2.0. Initially I got a large (I’m 6’2″ 180) but it was just slightly too big. Great service quickly swapping the sizes out. I now have the medium and am extremely happy. In fact my wife just got a pack as well. After several long runs I just used the pack on my first 100k. I was on course longer than expected (16+ hours) and wore the pack the whole time. I couldn’t be happier with the fit and performance. I’d highly recommend.

    Simply great. This is the best fitting bladder vest I have used. This vest fits snug, without constricting. It has the best hooking system on the market. The vest stays put for hours and hours, with a bladder that never falls down in the back. The thinking that was put in this vest is simple, smart and without any drawbacks. The vest has plenty of storage for fluids and fuel for very long runs.

    Good Stuff- Re-routed hose such that it runs between the front stays when parked- Reinforced rope connection in pockets too, because I over loaded pockets supporting a friend- I hav used five times or so n o w, and the usage was some h a r d stuff on Pemi loop and AT terrain nearby- Holding up well- I also hiked with lady wearing an astral, which was nice- New courses and longer sojourns hav been made possible using this creative vest- Thank you, Bryce Thatcher and everyone at ultraspire-

    The vest has been great. I am training for a 50 mile trail race at the end of the month and recently purchased the Astral. I have used it on runs ranging from 2.5 hours to 5 bourse. Supper comfortable and snug around my body. The elastic ties make it snug without being constricting. I really like the pockets for water bottles, and the reservoir adds huge capacity for long runs in the heat. I would like to see the side pockets s touch larger but all in all I am very happy about my purchased.

    I’m 6’3″ 180 and the Medium fits just right. I paced a buddy for a great deal of the Eastern States 100 this weekend wearing this vest. I ran 2x 20oz. bottles up front with my spare Petzl NAO battery, jacket, Tailwind, and a couple of Lara Bars in the back. It performed flawlessly. I love this pack. If you need a great pack for the weekend long run or the A race 100 miler…..this is the one. This is a great company with great customer service.

    The Alpha is a vest for long training runs. It has the capacity to hold plenty of fuel and water to not have to worry about running out mid-run. When it is fully loaded, it rides really well. I really like to put a collapsible bottle in one of the front pockets with a concentrated solution of First Endurance EFS, then chase it with water from the bladder.

    :

    My husband uses this hydration vest and loves it. Super lightweight and secures to his frame without bouncing around. He uses it for any runs lasting longer than 2 hours. If he is running longer than 4+ hours he will use the 2 liter reservoir and if shorter he will use a 1 liter reservoir. Both fit the vest nicely. He uses flasks for his calories and there is plenty of space in the front pockets for this, along with the pocket sleeves along the side for extra GU packets. I am looking forward to getting him one of the newer styles with the new front closure as the current titanium clasps are hard to undo when your hands are cold or when wearing gloves.

    I am a Clydesdale runner. 6’5″ and 215. I’ve tried many vests with no luck. The large Alpha 2.0 fits perfectly. My first run with it was 12 miles and I forgot I was wearing it. No bounce, stayed cool and plenty of storage. Thank you Ultraspire!!!
