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!

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 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.

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

Rides perfect while stand up paddling

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

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!

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.

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 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.

This pack is great on long runs

This pack is great on long runs. Stays in place, doesn't bounce around and keeps me hydrated. It is great because it allows me to stay ahead of my hydration, in the past I'd just deal with the side effects- which is not a good option

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.

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.

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.

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.
