Pinnacle 4L Hydration Vest

Pinnacle 4 liter

[This review was collected as part of a promotion.] Excellent fit plenty of storage. comfy

Functional/front bottles

Great, light-weight vest with two bottles and multiple pockets in front. There is an optional back bladder, or use the separated compartments for additional storage. High quality!

Bad bottles

The pack is great! The bottles have the hardest lids to put on. Like it’s a struggle for me to put the lids on without spilling water/mix everywhere. I thought it was just me, but even race volunteers ask for me to put the lid on the bottles because they can’t get them on. Once lids on are, bottles are good.

Good enough hydro vest

It took almost 3 weeks from purchase to arrive. In which I missed the widow for using it for my race. I ran 15 miles in it for a long run last weekend, I did feel bouncy/unsecure especially after drinking the water in the bladders. I have a similar pack from another brand, I was hoping this would be an upgrade but unfortunately not.

Super light and soft and carries a ton

Yes- you can put a 2L pouch in the back (sold separately). So, with 2L in the back and 2 x 600ml in the front, this light little slip of fabric can pretty comfortably hold 3.2L plus nutrition, your phone, TP and other essential stuff. The bite vales are designed really well- you get a really high fluid flow through them and they seal perfectly. The front bottles have a thin plastic firm strip embedded in one side- to make the otherwise flexible bottles easier to slip into the pockets. However- after 20mi, that firm side definitely did start to dig into my lower ribs. So I turned the bottles around. There’s zippered pocket on the inside of the front water bottles- big enough for a phone- but having a hard phone in that location would get uncomfortable. Instead - I shoved my phone in either of the lower rear back pockets that are easy to reach. No matter how perfect and sorted out each of these products is- none are ever perfect. Anyway- this will make a great fast pack for my upcoming ultras. Nathan does a great job with this one.

Really tight…weird

I have the Nathan pinnacle in the light blue 12L version. I got the exact same size so I clipped the tags off and went to take this for a run. Wow it’s so much tighter which really confuses me. They are both pinnacle packs and the size chart looks the same to me. This one I have at its loosest adjustment while the other one I can pull it halfway with a full bladder. Disappointed in this one. It honestly feels like it’s a size down and labeled incorrectly.

Solid Vest

[This review was collected as part of a promotion.] I have had this vest now for a couple years and have taken it everywhere. OCR, many ultras, snow, extreme heat you name it. At this point its still holding up even after several cycles the the washer. My only critique would be the magnetic attachment for the hose to the vets. I lost it with in the first couple weeks would like to see that be permanently attached. Favorite Features - Water resistant zip pockets Easy access side pockets Allows you to carry more than enough hydration than you'll need

Great purchase, highly recommend.

[This review was collected as part of a promotion.] I absolutely love this hydration pack. I have only used a few different brands from when I was in the military that would always bounce, the straps would come loose, the packs would be ill fitting etc. I am training for a 50 miler next month and decided to pull the trigger. I chose the pinnacle 4L because it had some good reviews and obviously I trust the brand. That being said it outperformed my expectations. Smooth, fitting, comfortable, no bounce, straps stay tight as you put them. Absolutely recommend!

Luv it

Fits really well 100k with it tommorow.

Hydration Vest

Vest works well. I am in between S and M. I ordered a small. My only recommendation would be to increase the strap length to provide more flexibility with fitting. The bottom strap is extended all the way out and works but it would be nice to have more length. Thank you.
