    The Astral 3.0 is by far my favorite pack! I’ve upgraded from my original Astral to the 3.0 version. I like how the pockets fit flat against the front and I can fit a large bottle in the front pocket, plus it expands if I need to carry more. It hold about 2 liters more, so I have more storage in the back too.

    My first run with this vest was a 9 miler. I wanted to get an initial feel for it before I took it out for a much longer run. This vest holds a 2L bladder, plus it has a pocket for a flask. Now does one typically need 2L of fluid to run 9 miles? No. But I wanted to see how it felt.
    I filled the bladder up, maneuvered the straw/hose through all the little holes, straps and clips and then filled up the flask and slipped it into the front pocket. I made some minor adjustments to the fit of the vest now that it has the weight of the water. It was digging into my pits a bit and I knew it would cause issues. I just loosened up the side adjustments and tightened up the top bungee and I was all set. The weight distribution was great. No bounce, no discomfort. I had no idea until I got home and weighed it that I was carrying around an extra 6-7lbs. I would have never guessed because it felt so comfortable and effortless!
    Plus look at that design! Those straps are not sitting right on top of the “girls”. They aren’t restrictive in any way and it doesn’t feel like you’re being squished anymore than what your sports bra may already be doing.

    I’ve used this vest on a few long runs so far (15+ miles) and I love it. I was hesitant at first based on the price, but I think it’s well worth it. The vest is very well-made: high quality material, intelligent design, and lots of storage. Consider me an UltraSpire convert.

    I have been using this vest every Saturday long run for the last year and for the most part I love it. The vest feels great and doesn’t bother me on long runs. But, after 1 year the two zipper compartments have issues. The small zipper compartment at the top came lose and I had to sew it back down. It worked fine after that. The bottem zipper compartment is now getting stuck more and more and is hard to open/close. That zipper has always been hard to open/close while on the run. I love this vest but I wish the bottom zipper compartment was replaced with a duplicate of the other side with maybe a magnetic or elastic string closure/loop. Overall this is still the best 1.5-2.0 liter vest for women – especially those of us a little busty on the top.
