Real Customer Reviews

Love It!

This is exactly what I was looking for in a hydration pack, something light that doesn't budge when I run. I ran 8 miles with it today and forgot it was on my back. The neoprene forms so well to your back that it almost feels like it is stuck to it. I can't wait to try it in the water.

Five Stars

Cute pack. Small just what I wanted

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 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.

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.

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!

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!

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 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!

The DolfinPack Lightweight does as it was advertised. Light ...

The DolfinPack Lightweight does as it was advertised. Light and compact, I can see myself running with it on my back. Don't buy this product if you expect to carry big items in the pack with the water bladder filled. I fit a wallet, keys, and squeezed a 100 page 8"x 11" magazine in the pack with a little struggle. All in all, I can see myself using this item for many outdoor adventures with and without a shirt.

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.

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

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

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

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
