Real Customer Reviews

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 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.

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

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

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

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.

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.

Rides perfect while stand up paddling

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

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

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.

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.

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.
