Real Customer Reviews

is easy to fill and nice looking

This has saved me during the heat wave we've had in the Northeast - it's light, is easy to fill and nice looking. Great product

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.

Wore this for my first spartan beast and it was ...

Wore this for my first spartan beast and it was so light I sometimes thought I had low water. Filled it once on the 14 mile course and could even fit my Gu packs and nuun tablets inside the pouch!

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.

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.

This hydration pack is light and comfortable. I used it for an 8 mile Spartan

This hydration pack is light and comfortable. I used it for an 8 mile Spartan run and it did a fine job. Lately, I have taken out the reservoir and relied on the water at the water stations. Instead I have used it to carry gels and goos as well as any items (layers) I remove while running. Comfortable and versatile.

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

Great Spartan Race water pack!

Used this for a Spartan Super and it went great! Definitely much slimmer compared to traditional water backpacks and kept out the mud that I was rolling around it. Also, there is plenty of room to store energy gels in the large compartment for during race energy. This is already cleaned and ready for the upcoming Beast!

Best Hydration Pack, Hands Down! Very Pleased!!!

I just ran a Spartan race and was concerned about my Camelbak absorbing too much water and holding lots of mud while I ran. So I ordered this Dolfin Pack to use instead. Definitely the best decision I could have made. This pack is super comfortable and light. It fits securely and thanks to the neoprene, it did not chafe me in the least even when I was soaking wet. Since the straps are fitted using velcro instead of buckles, adjustments were easy and fast. Plus the pack did not shift as I drank the water.
No mud stayed inside due to the drain holes in the bottom so I had zero added weight from mud and muck.
The water storage capacity is perfect. I did not fill mine completely full so I had a bit of space to include a waterproof bag with a tracker inside for my husband to follow my progress with. There is no additional storage space otherwise. I'm a bit torn on whether I would want that or not as it could compromise how the pack fits and drains but for a longer race, I will need to have fuel like GU or NUUN tabs with me so I may need to find another way to do that.
I did have to use a bit more pressure on this bite valve to get water out but it wasn't anything that affected my thoughts on the pack.
This thing was completely coated with mud after the race but washed clean in only a couple minutes with cool water and a cleaning brush. This will now be the pack I use for every race I run. I have a beast in August and a half marathon in Sept. and I plan to use this pack for all my OCRs.
Thank you Dolfin Pack!! I was not paid to write this or given anything for a good review so this is what I truly think of the product.
Since this worked so well, I am also looking at the hydration armband for short runs. Once you find something this good, you stick with ti!

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

Great for Spartans

I bought this for a Spartan race and it worked very well. The velcro fasteners worked well for keeping it high on my back and not bouncing around. The dust cover is key for not getting a muddy mouthpiece to drink from. Plus the holes in the back drain out all the water and mud.

Rides perfect while stand up paddling

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

Five Stars

Cute pack. Small just what I wanted

lightweight, secure, quality

My son gets so hot and dehydrated running. He asked me to find something that wouldn't bounce around. This has great padded straps and a cross strap to make sure it doesn't slosh around. He does need to make sure he gets ALL the air out before starting to run. He calls it burping the dolphin. Nice wide opening to clean it out. I put paper towels inside to let it air dry

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.
