Running vest

This is by far the most comfortable running vest I have owned. I have chronic neck issues and any offset weight can make long activities unbearable. I find the ergonomic construction of this vest superb, even filled with fluid and trail goodies. Balanced and comfortable throughout the miles. Durable and easy to care for, too.

Love it, zero bounce

I've used it on a full and a half marathon, and could not be happier. It rides high on the back so I don't get the chaffing in the middle back that I have experienced with other packs once I start sweating. The side cinch straps are helpful to keep it secure as you start consuming fluids and nutrition. Won't use another pack again!

Endurance pack 2.0

I ordered my endurance pack 2.0. I needed a water pack that would allow me to go on longer runs without running with multiple water bottles. This pack has worked great so far. Had it for about 2 weeks and it is light and compact. Makes it feel like your running with no additional weight. Also when I ordered my pack I assumed it would take several weeks to get delivered to me. This was not the case Orange mud had this pack delivered to me with 3 or 4 days. Turn around time was awesome! Definitely recommend this company and running pack!

Great product

I bought this running pack more for walking than running. However, from time to time I will jog or sprint with this on. As a career Soldier, I have run with all sorts of gear on in my life. I have never run with anything as stable and compact with no jostle or drag. Fabulous product.

Many passerby’s are interested in this pack as the see me go by or pass me. Many have not seen anything like it.

I don’t like that the draw strings on the front of the pack to tighten the two bottle fasteners open towards your neck. These could have easily been put towards the outside, to prevent chaffing while drawn.

The hydro pack for water is a great size. I usually use 100 oz, so adapting to only 68 ounces is something to work thru. The tension system to keep the water steady is great. I could have used exactly ONE more inch of distance in the hose. As it is I have to turn my head to he right Slightly to drink.

The pack should have a tension system to allow the pack to wear higher. The side straps only tighten the device, but there really isn’t a good means to rotate the pack to sit higher. This would take some redesign however. On this note, the shoulder width does not seem to adjust to fit. The side straps affect the chest size, but if your shoulders are not broad enough, the shoulder straps sit right above the shoulder ball and socket instead of the more comfortable portion of the shoulder between neck and shoulder.

The front straps are elastic and lose tension on the…

Solid pack that does the job

This is the second orangemud product I’ve purchased. When it came time to start training for my first marathon, I looked at so many hydration vest!! After researching and reading many reviews, I knew this endurance pack would meet my needs and I wasn’t wrong. It holds a 2L bladder, room for my iPhone 11, nutrition, plus much more. Just note that the best may rub your arms depending on how your front pockets are filled. A little body glide solves the issue. Solid pack that does the job.
