Real Customer Reviews

I absolutely love my DolfinPack

I absolutely love my DolfinPack! It's comfortable to wear and does the job I need. I mostly use it for Spartan Races, but have taken it on canoe and kayak outings, as well as runs around the neighborhood or on trails. The water bladder holds enough to get me through all my evens. It is easy to clean and doesn't hold smells (like from preworkout or BCAA powder). The neoprene pack washes clean after each race! I can throw my keys, snacks, or anything inside and am not concerned about losing them! I highly recommend this pack!

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

Simple, streamlined, perfect solution

If you are looking for a ligthtweight alternative to a Camelbak, this is for you. If you are a petite person (I'm 5' and 100 lbs) frustrated by gear that is too big and therefore chafes and throws you off balance, this is for you. It's easy to put on, easy to wear, and easy to clean. The bite straw is efficient and easily tucks into the elastic loops. You can put a phone in the pack with the bladder if you are in an area with low humidity (due to condensation); just seal the cap well. The only catch-22 is that the super adjustable and sturdy velcro on the straps can snag your shirt if you don't align them perfectly.

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

Done well so far in OCR

Needed a affordable but reliable pack for OCR racing, and so far this has done well. Took it through a 14 mile Spartan Beast and for a few laps (15 out of 25 miles) during a Battlefrog Xtreme. Fits tight, no extra bounces, and so far hasn't fallen apart anywhere even if wet and caked with mud. Only downside is lack of places to store nutrients if needed, but its sole purpose is hydration and it does that well!

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

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 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.

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.

Great Product

Great water pack for an active lifestyle.
I have been using it for trail running and have not had any problems with it rubbing or bouncing.
The only thing I can see it needing is a pouch to place energy chews.

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.

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

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.

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!

Five Stars

Cute pack. Small just what I wanted
