SiS Go Isotonic Energy Gel

Easily digested gel

As far as I am concerned, one of the finest gels. Once the pack is open, the gel is easy to swallow without the need for water.

Pros & Cons

SiS Go Isotonic Energy Gel provides optimal replenishment of simple & multiple carbohydrates. Ideal for use during training or competition!

Pros & Cons

Fine gels with a nice flavour. Packing is easy to open with your teeth while cycling. Squeezing the gel is also easy

Pros & Cons

Been using the gels for several years the taste is good, and it does what it is supposed to do

Pros & Cons

Used for long endurance runs

Great taste and thickness, my marathon workouts go super with it.

Pros & Cons

An energy gel that goes into the body quite quickly and out quite quickly. Excellent for Zwift sessions.

Super product

Easy to use nutrition for my long endurance runs

Pros & Cons

Very satisfied!

Pros & Cons

If you can wait a few days, this is the place to be

Fine sports gel for longer distances. As the contents are pleasantly liquid, easy to swallow while running

Pros & Cons

Top: Bulk buying is a godsend, super handy if you're training for a marathon. You need a lot of them, so having such a big supply is top and saves on costs. Tastes great, you have to work it in while running anyway, so nice that it tastes good. Easy to take while running, even when you're at pace you can take this gel without fuss. No water needed, so it runs nicely. Less: Tricky to open with cold fingers: When it's cold outside, a pack like this is sometimes a struggle to get open. The texture might be a thing: The thickness or stickiness for people might be a minus point. It leaves white streaks. Taking mess with it, after taking it you're stuck with that empty pouch. Not ideal during a long run.

Pros & Cons

I had to go to the toilet right away. my stomach can't stand SiS. Now order Maerten. Is a lot more expensive but I can keep it down.

compliant item, easy to use and good taste

Super handy on the go during a long bike ride.

Pros & Cons

I managed to open and consume the gels while running, so very satisfied!

Pros & Cons

Very fine gels for training marathon, only bought large pack immediately before marathon itself, but shelf life is too short, this could have been mentioned

Pros & Cons

As a triathlete, I use these gels during my races. They are easy to carry, tear open and squeeze empty while cycling and running. They give enough energy to last for a while

Pros & Cons

Been using it for years: "have a break" extra boost!!!

Ideal, see pluses, goes in like a sweet. Necessary energy is delivered quickly.

Pros & Cons

Good product, easy to use, helped me well in my racing and training

Pros & Cons

SiS has all kinds of tasty and good products, but not these. I thought they were expired, but a quick search on the internet and no: these gels have 'texture'. I can't get them in. I read that you could give them a good shake to get rid of it, but it doesn't work for me.

Pros & Cons

Excellent and has been using it for a long time

Pros & Cons

Perfect during endurance runs and bike rides!

Pros & Cons

easy to use

Packaging works easily , gives just that extra boost

The pack is difficult to open, but gives enough energy and has a fine taste

Easy to carry gel for long endurance sports training and water is not needed

Pros & Cons

Great for during races

Pros & Cons

Tricky to open otherwise okay

Pros & Cons

persoonlijk geven deze gelletjes mij het beste effect en geen gastro-klachten.

Pros & Cons

SiS Go isotonic energy gel is/are very fine gels to use when cycling, among other things. The quality is unbeatable as far as I am concerned.

Pros & Cons

SiS Go isotonic energy gel is/are very fine gels to use when cycling, among other things. The quality is unbeatable as far as I am concerned.

Pros & Cons

I have bought sis gels from Mantel several times. Always delivered on time. Very long shelf life.

Once again, like all SIS products, it contains all the nutrients a cyclist needs.

I have now tried all the flavours and find them quite palatable. They work fast and my tummy can handle them well too. Tropical and blackcurrant are my favourites.

Pros & Cons

Fully meets my expectations

I have been using SIS for a long time and it is simply an excellent product. It does exactly what it should do: deliver energy quickly.

Pros & Cons

Excellent product, good taste, digests well!

Excellent gel

Pros & Cons

Nice

Pros & Cons

The difficulty of absorbing other brands led me to try this SIS product, which is really top-notch. Excellent gel, easy to swallow (even during high-intensity races). It's quite liquid and tastes great in the mouth.

As good as it gets

Pros & Cons

tab should be able to stick to packet

Pros & Cons

Handy to carry came in handy on a brisk bike ride

Pros & Cons

Used in conjunction with canteens with matodestrine and bars, useful before long climbs and in the second of 5/6 hour rides to make up for energy dips, it is consumed and assimilated well without the need to drink large amounts of water, any residue on the bike is difficult to remove due to the high sugar component.

Pros & Cons

Super

Pros & Cons

I always take extra gels than I think I need. Then, should I be surprised by hunger/faintness, I always have some left over. Gels are great for this. I had also tried gels from Kruidvat before this, but the quality of those just doesn't make it: you get rid of these more easily, they don't taste like the enamel is burning off your teeth, and I get the idea that I digest them faster/convert into energy faster, too.

Pros & Cons

I always have these SiS gels with me during (long) tours and cyclosportives; they are tasty (not too sweet), give lots of energy and are easy to carry.

Pros & Cons

Good quantity. Taste less gross than other tastes

Pros & Cons

Easy to get rid of without water and not too sweet.

Pros & Cons

Most of the ones I use are on the stomach ( use 2/3 per hour ) and I can easily take these for 2 hours at a time without getting it on my stomach.

Pros & Cons

80 years old, 2 bike rides a week with the club. 1 gel per hour of practice

Pros & Cons

Great products, as always with SIS. The gels are free-flowing, very tasty and easy to assimilate, just great! Free, ultra-fast delivery with Mantel.

Pros & Cons

Excellent energy gel

Pros & Cons

I also use these gels with running during endurance runs. Is still preferred by me over eating bars because it has a quick effect and you get fluids at the same time.

Pros & Cons

Been riding this stuff for years, very satisfied with it

Pros & Cons

After long rites no I put a few on

Pros & Cons

Good taste. Not too sweet. Pleasant substance. Sufficient energy in a gel.

Pros & Cons

Practical and very digestible, excellent energy supply, I personally use one every 30/40 km.

Pros & Cons

I was pleasantly surprised by how easy it was to empty and swallow. A light sweetness that does not cloy. Phenomenal price. For me it rivals Maurten

Pros & Cons

The composition is excellent and, above all, the product doesn't have an overly sweet taste that disgusts. It also remains fairly liquid compared with other gels, which I digest much better than the brand I used before.

Pros & Cons

After using quite a few gels, I think this one is one of the better ones. Often it becomes a sticky mess when you use one while cycling, but not at all with this one. Easy to take during exercise.....

Pros & Cons

The best gels I have ever tried. More liquid, less sticky and fresher.

Pros & Cons

On my first bike ride, I definitely needed gell and it helped me complete my first 75km ride

Pros & Cons

My first introduction to sports gel. Great taste, good value for money. I will order more

Pros & Cons

Efficient use, glides in smoothly.

Pros & Cons

I usually use before and during training with good results.

Pros & Cons

Is a good addition to other healthy snacks to take with you on long drives (100+)

Pros & Cons

Great gel, easy to digest and drink on the go. The only problem you end up with two pieces when opening - better to have design like PowerGel or AMACX.

Pros & Cons

Ideal gel for during long endurance runs or (half) marathons. I have quick bowel problems, Mar these gels fall fine even with me. No bad taste either, for what it is quite tasty. Looks like melted Calippo ice cream, especially the Lime variant is pleasant in taste. Last but not least, doesn t do what it is supposed to do, instantly give new energy so your legs don t fill up!

Pros & Cons

Super product, even in cold weather, the product doesn't freeze, it stays intact - nothing to complain about. Would definitely recommend

Pros & Cons

Format absolutely fine. The tear-off part tears easily all the way through, which others can do better. So you quickly have a mini piece of wrapper in your hand. The taste resembles a mixture of toilet stone and an imitation of lime flavour. Once it is down, it is very well tolerated.

Pros & Cons

I like the taste, feel like my legs went round a bit better uphill again :-)

Pros & Cons

It suits me perfectly. Easy to eat and it doesn't make you thirsty. The only disadvantage is littering, i.e. tearing off the flap (lid) with your mouth and then spitting it out.

Pros & Cons

The SiS Go Isotonic Energy Gel is a great gel for during endurance sports. Easy to open at the top without having the contents sticking to your fingers. The taste is fine, similar to other gels and the advantage of this one is that you don't need to take the gel with water.

Pros & Cons

Ideal stuff for when you're in danger of running out of steam

The gels are easy to swallow and provide the necessary boost for half an hour. The only drawback is that when you open them with your mouth, it's hard not to lose the little piece of packaging that has been torn off.

Pros & Cons

During sports, always handy to take with you.

Pros & Cons

Been using the gels for years on longer endurance runs (>60min), gives just the energy to come across fresh. Also an excellent source of energy when cycling/MTB.

Pros & Cons

The parcel was received on time. The gel has a good taste.

Pros & Cons

Easy to carry in one of the back pockets of my cycling jersey

Pros & Cons

Nice flavour, not too pronounced. Good liquid, ideal for hot days. No "full" feeling, that's what energy bars are for. Open easily and good in dose!

Pros & Cons

Delivers good energy, but too sour for my taste.

Perfect consistency compared to other brands the Apple flavor isn't as sickly sweet as other flavors which is perfect to prevent gut rot on a ride

Pros & Cons

zoals gewoonlijk snelle vlotte levering. mijn favoriet gel: is vlot te drinken tijdens de inspanning en vlot verteerbaar.

Pros & Cons

Used for the first time on 200km ride. Works well to keep your energy levels up!
