Nathan  Pinnacle Pro 6 L Hydration Vest

Extremely comfortable, plenty of pockets, and fits really well! The new design is pretty nice and I love the colors, the thinner cinch-straps take some getting used to - but I appreciate that they kept the pockets similar to past Pinnacle design. The material is just as soft and strong as before, so it’s quite comfortable yet I don’t have to worry about scratching or ripping the fabric while hiking/scrambling through brambles or thick vegetation. I’ve used it mountain biking, morel & shed hunting, birding, general hiking, and also threw it in my bag for a backpacking trip to use for day hikes away from camp and it was perfect!! With the water bladder full and/or the pack pretty full, you’ll have to have the chest straps pretty loosened out, but as you drink down the water it gets more comfortable/cinches back down.

I love this vest! It’s very lightweight and does not feel like I’m wearing a bulky annoying vest! It has so many pockets to hol all my things. I absolutely love this vest and can’t recommend it enough:)

I got this vest last summer just a few weeks before a 42k trail race, it had no break in period and I've never had any issues with chafing (note: I haven't tried it with just a sport bra). Things I love: - lots of water storage! I've rarely needed to use the back reservoir but it's great piece of mind when I do fill it. Also the seal for the rear reservoir is slick. - the adjustable straps on the front. not only for easy tightening and loosening but the ability to adjust vertically up and down, which is helpful depending on layers and what you are packing in your pockets - lightweight and breathable - some secure zipper storage - no bouncing of the water bottle straws, little straps keep them in place. they also have an elastic loop but I've discovered I don't need to futz with that so stopped using it. - lots of other storage, you can carry phone, keys, lots of snacks, roll of dog bags, etc without any issue. I can stuff a layer in the back and it's still super comfortable. Things I would change if I could: - the freaking tops of the hyrdapak bottles are a nightmare. 8 months of solid use and i dread trying to get them seated and sealed. every. single. time. I should just cave and buy new ones, I guess. - the tube from the rear reservoir... I haven't quite figured out the best way to store it so it just hangs tucked between the front straps. that works, but feels like it should have a more official home - the storage pockets wrap all the way around so your items can migrate, making them tricky to access. I think I'd prefer a seam on the side and another access point on the back. - the front hydrapak bottles have a plastic piece in them to help with shoving them in your pockets... just be sure to always load them with the plastic facing out, otherwise you might get some bruising on your rib cage. All in all, a great option for anyone looking to upgrade their running vest.

Ran my first ultra marathon with this pack and was so pleased. I have struggled with finding something that didn't shift during movement. The pack never moved, yet felt light and seamless. I was happy to adjust the ties as my fuel depleted from the pouches. Would recommend to all my friends.

I've been using this vest on Sunday long runs and really enjoying it! The fit is great—snug but not restrictive, and the elastic front closure is a huge improvement over previous clip versions. I've had under arm and neck chaffing in the past but haven't had any issues with this product. It moves with me and feels much more comfortable on long runs. The only minor downside is that the water in the reservoir does slosh around a bit, even with burbing it, but that’s expected with any hydration pack. There are pockets in the front for soft flasks when you don't need the full bladder.

[This review was collected as part of a promotion.] The Nathan Pinnacle Pro 6L hydration vest is GORGEOUS and impresses with its perfect fit, ample storage, and smart design. The adjustable straps ensure a snug yet comfortable fit, preventing any bouncing during runs. I'm obsessed with the well-placed pockets that make it easy to access my (birthday cake) gels and my phone! The lightweight materials and mesh back provide excellent ventilation, keeping me cool and dry. This vest is practical, durable, may I say, gorgeous. Highly recommend it for any runner wanting to look and feel AMAZING!

This vest is comfortable and fits well. The fabric is soft and breathable. The chest compression straps have no stretch and can dig into your abdomen when cinched down all the way, which is uncomfortable. The connection points also tend to migrate up or down which can change the fit mid-run. The included hydration soft flasks have a rigid "spine" in them which started to bruise my ribs on a long run. The layered pockets on the back of the pack are hard to differentiate between when reaching back to stow gear.

Size small was a comfortable fit for my frame (5'3", 135lbs). Lots of ways to adjust the fit, but I wish there was a way to stow/corral the extra cord as I find it distracting when it's flopping around during the run. Nice to have hydration flasks, plus the option of a bladder if it's going to be super hot or a really long outing. I wore for a trail 1/2 marathon and it easily held everything I needed. Fabric is soft and lightweight, no crinkly noise. Additional lighter color option would be nice.

I used the vest for long runs. It has multiple options to adjust it to your body. What I really like about it is the fact that I don't feel it when I run. I did have to spend 5 min to ensure I pull a in all the right places to ensure all is adjusted to my body. The bottles are very good too. They are flexible and easy to squeeze. The only suggestion I would have is to isolate the bottles better so they can keep lower temperature. All-in -all, I recommend this vest, you will enjoy running with it.

I am a 60 year old runner and I got this vest as a gift from my children. The size inside the vest says L/G. I am assuming that means large. My sternum measurement is 40 Inches. The vest I have feels very small on me. The sinch straps ride up to the very top. I cannot keep them down where they belong when I am running. The long tubes put the access for my mouth when running in a position where I really have to kink my neck to take a drink. Overall, I find it not very comfortable to run in.
