Endurance Pack V2.0: Ideal for running and biking

Fit was a bit tough to nail down. I tend to rub the front pockets with the inside of my arm. Elastic in front is not very secure, but as a light weight pack, it has everything you need. I normally use the double barrel, but wanted /needed more water for longer trail runs/hikes

This pack was definitely what I was looking for. ultralight overnights are a breeze with this pack.

I got the neon green version of this on a sweet clearance deal. I'm certain the V3.0 is amazing too but I am cheap and I have some buddies that use this one so figured I'd give it a shot.

Longest run so far is about 13 miles, no chaffing noticed. I did a 10 mile run/walk/hike yesterday wearing the pack over a tank top and no issues at all with chaffing which is impressive.

I have had it for about 2 months now and I will say the most important thing to do with this pack is just take the time to put it on in different configurations to figure out how you need to tighten/loosen the straps. Depending on how much you have in the back bladder, stuff sack area and how much liquid you are carrying up front you'll have to make adjustments. I'm still getting this part down but once I have it dialed in it sits right in the middle of my upper back and doesn't bounce at all! In fact even when I don't have it quite perfect the only difference for me is where the front water pouches sit on my chest. I like them close to center so I end up messing with the back straps to get it just right. Either way no bouncing no chaffing and plenty of storage.

This past adventure I put my S22 phone in the front pocket in front of the water bladder I had in there (once the water was about gone) it didn't bother me at all.

If you like the less is more approach and need an open design so it's not like wearing a jacket when you run this is it!

I have been a competitive runner for twelve years now. Recently I have been into climbing mountains and running ultras. My hydration belt has served my purpose but I now have other needs. Last night I wore this vest for the first of many times to come. I have a 24 hour ultra next month and it is perfect timing to get acclimated to it. So far it seems comfortable.

I had been searching for a long time to find a hydration pack that fit my needs on my long runs and ultra races. I found it in your product :) The endurance pack with the 2 litre bladder was perfect! It rode high on my back, fit snugly, didn't chafe, and had plenty of storage. Loved everything about it!
