Real Customer Reviews

Lightweight, small, and easy to run with!

So I have only used this once, but I really loved my first experience with it! I have had others in the past and like so many elements of this one way better. I use this for longer distance runs or will use in the summer when its too hot to run without water.

I like the material, it feels very water friendly for all the sweat that I get on it ;) It was very lightweight and didn't jiggle around at all! Even the water in the bladder didn't bother me, I couldn't hear it over my tunes playing. I am slightly worried that the velcro will wear out, but I'll cross that bridge if it happens then!

The mouthpiece is very easy to bit down on and there is a on/off switch which is a really nice feature.

The position on the chest may be a little funky for women with larger breasts. While my chest is rather small, I did not have this issue, but due to the placement of the straps, I'm not sure if they would fit well under larger ones or make them uncomfortable?

But overall I like how small and lightweight this is! Perfect for just the right amount of water needed for a 2-3 hour run :)

don't know it is on my back!

I do SUP. It is very well made out of neoprene. Excellent for water sports like SUP. It holds enough water ...about 1.5 L.
Even when full I do not notice it is on my back. It does not slide when paddling. Most of the times I do not wear a T shirt and there is no chafing. You can still fit your cellphone and keys. Will buy it again. thanks

Great pack for Spartan and other OCR races!

Son wanted to do a Spartan Race, but he has Type 1 diabetes and needed a pack that could carry supplies and withstand the rigors of the race. Spent several hours researching pack options and happened to see an excellent review of this pack on YouTube.

The pack is small, lightweight, and fits comfortably on the back with minimal slippage during the race. The neoprene material doesn't soak up water adding unnecessary weight. The velcro closure was tight and prevented anything falling out of the pack. The bottom drain holes worked perfectly in all water events - each hole is grommeted to protect against tearing or ripping. I couldn't find any other pack that had this absolutely essential self-draining feature. Although the pack was small, there was ample room for the 1.5L bladder, diabetic supplies, and snacks.

Will use this for all future races and have recommended it highly to other OCR racers. Very satisfied with this purchase. Item arrived quickly and was well-packaged.

Perfect hydration back pack

This is my original go to OCR hydration pack and typically the one I use for anything over 12-13 miles it small and out of the way so it doesn’t snag up and very durable! It’s also the only piece of gear not stained from the South Carolina Spartan Beast in 2017

Customer service is PHENOMENAL!

I purchased my DolfinPack mainly for Spartan OCRs and for my long runs. I researched several different brands and found this one to be a great fit for my needs. I have had it for about 7 months and I absolutely love how lightweight this product is, the material is breathable (need that in a Florida!) and it does the job. I did have to request a replacement after 6 months when I noticed that the seams started coming apart on one side and the strap began ripping. However, I still give this product 5 stars because the customer service is PHENOMENAL because within 24 hours of putting in my initial request (on a Sunday, no less) my replacement was already on its way to me. One thing I do wish it did have was an exterior pocket for fuel and/or keys so I don't have to put in the main pocket with my hydration pack.

Light weight

I bought this for my grandson for his birthday. He and his dad go on long hikes so this make things so much easier now that he doesn't have to carry his water bottle! It is very light weight.

These guys are great. Great product would highly recommend

These guys are great. Great product would highly recommend. I've run 2 Spartan races (Super and Beast) with this pack. With it being made from the lightweight material hardly knew it was on. Also was able to get some energy packs stuffed in with no problem.

Great Running/Outdoor Hydration

I needed a water source for long runs in south Florida where hydration is important. I LOVE this. It fits me perfectly and is extremely light in its construction. The neoprene is great. I didn't like the camelback because of the heavy canvas straps and the canvas body - all I could feel was bulky and chafing. It has a small place for the gu if you use that, but no where really to hold your phone - I just tuck it into the strap and it works fine.

Perfect for OCR Sprints

Bought this for an OCR race after reading a number of reviews. It’s the perfect pack for hot recess. I soaked the neoprene pre-race and it helped my back stay cool during the race. While there isn’t a dedicated pocket, I was able to stuff my gloves, a small rag and some energy gems in the main compartment where the reservoir goes.

It comes with a 1.5l reservoir. I was able to fit a 2l reservoir in it but it was a wider/not longer reservoir.

Nice hydro for active sports

I am a fan of the low profile minimal design
I use this when I don't need three litres and storage on my motorcycle

Rides perfect while stand up paddling

Perfect for paddle boarding with the close fit and drain holes. No more lugging around bottles.

Perfect for skiing or snowboarding

I use this pack for skiing and it fits perfect - high enough on my back that I don't even feel it on the chair lift. It feels too tight with layers of clothing underneath but I usually just leave the straps loose. I am 6'1" and 180 pounds.

Great Hydration Pack and Awesome Customer Service

Bought this for my wife to use while on a standup paddle board. She loves it, It's very comfortable, simple and not fussy with a lot of buckles and straps. Seven months later some of the stitching started to come apart so I contacted DolfinPack through their website and was surprised with a very prompt response. I sent them some pictures of the stitching and FOUR days later - shipped to HAWAII - a replacement was in my mailbox! I don't know if anyone could expect better customer service. I was going to wait for my current hydration pack to fall apart before replacing it but am so impressed that I ordered a DolfinPack for myself.

Perfect for marathon training

This pack is working great. I am using it for marathon training. Slim and it doesn’t bounce hardly at all. Also love the neoprene material. I have not had any chafing. I do put bodily glide where the pack potentially may rub. I have worn this on a 17 mile run

Five Stars

Cute pack. Small just what I wanted
