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.

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.

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!

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

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.

Rides perfect while stand up paddling

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

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

In Lake Tahoe 10/1/16 in this and was extremely satisfied, light weight

Ran the Spartan Beast in Lake Tahoe 10/1/16 in this and was extremely satisfied, light weight, low profile and durable. The Velcro worked well and never came loose, only knock is if you use the dust cap the holder doesn't work, I brought my own Velcro strip to hold it in place while I ran. Overall great buy and will use it in all of the longer Spartan runs and in training. Also since there are no pockets I filled 3/4 full and there was plenty of room to put a Ziploc bag with my energy beans, salt tabs and beef jerky.

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.

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

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!

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.

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.

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!

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.
