Real Customer Reviews

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.

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.

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 :)

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.

Rides perfect while stand up paddling

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

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

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!

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

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.

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 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

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!

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.

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
