Real Customer Reviews

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.

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 :)

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

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.

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.

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

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.

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.

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

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.

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

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

Awesome!

On the suggestion of a friend, I ordered this for the Spartan Super. I am small (5'3", 118 lbs.) and many other hydration packs are too bulky, take on too much water (during obstacles), or chafe. This pack is awesome! Extremely low profile with soft straps. It velcros across the front just under the breasts.

Note that there is no zipper pocket for fuel, but in the large pouch which contains the bladder, I put chews, gel, and a protein bar no problem. My Spartan teammate had that in hers plus compression sleeves and gloves.

Highly recommend!

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.
