sized pretty small

  • Familiarity: I returned this product before using it

Great idea. M/L was too small for me - I'm 5'8" 170. Wish it were larger

Does this come with a hydration bladder?

Best Answer Responded on

It does not. My 2L camelbak fits in it like a glove if you're looking for one to drop into it, however.

A solid choice for longer runs

  • Familiarity: I've put it through the wringer

I have used this vest on many 3+ hr runs and one 8+ hr run over 3 months. I typically use a 50L bladder for 3 hr runs and add a 24oz bottle for longer outings. I carry about 200 calories/hour on such runs. I typically carry a small blister kit and of course a little TP for emergencies. This pack works great for this.

On longer runs Ive added a map, GPS, spare socks and headlamp or once, a super lightweight harness, belay device and 100 feet of 7mm tag line.

The vest remains comfortable regardless of load or sweating. I think the wide shoulder straps, side elastic design and adjustable double front straps works very well. Even on hot days I didnt feel any hotter for having the vest on.

The bladder pocket is made for a 50L bladder and you can cram in a pair of socks too but that is about it. You can route the hose under arm or over shoulder to either side in a low profile manner. There are 4 front pockets. The two low ones can easily accommodate standard size 24 oz bottles or lots of snacks but not both in any one pocket. The upper pockets seem ridiculously small at first but the zippered one holds a small blister kit and a tube of lip balm fine and the velcro one just barely holds a handheld GPS or full sized cell phone. There is also a small zippered pocket low on the back that holds keys, some TP or other small stuff. You can add bungee or cord to the back to hold a rain or wind shell or some other small amount of gear you might need.

The front pocket sizing is the limiting factor for self supported outings. For me, I was able to go 6-6.5 hours with a bladder, one 24 oz bottle and the other large front pocket full of snacks. Obviously this is subjective but Im throwing it out there as a ballpark planning factor.

Finally, the price is fantastic for what you get. It was a major decision factor for me and Im not disappointed.

While Ive seen some other cool vests out there, Id buy this one again. Its well built and has a great price point.

Anything else you can share that you've learned would be much appreciated. Running 13 miles on trails so far, am going to venture further. Your comments help tremendously and I can spend more time running than learning the ropes. Thank you!!

I guess you meant a 1.5 L or 50oz bladder not 10 gallons ;) ,thanks for the nice description of the vest.

If I was a runner...

I would purchase this hydration vest. Mainly because of the simple design. It is light weight, highly breathable yet can carry all the essentials needed while on a long trail run. If you put a lot of miles out there on the trail, think about this as a purchase to add to your gear closet.

was curious if you think you could fit water bottles in the two front pockets?

Not much running or showing this vest out in the field.

This is a brand video provided by Mountain Hardwear. I am sad that you dont like it.

Responded on

Just to say it is lightweight and you can put food for the day, nice view but too short comments on the use and capacities of the vest I think.

Responded on

Yes. There's not a full view on the wearer to see how the vest fits or handles while running.
