The nutritional base of ISO Fish with a sweet character

What makes Mainline ISO Sweet special is the combination of the nutritional properties of the ISO Fish mix with a pronounced sweet attraction profile. This brings together two key features of modern carp boilies: a high-quality nutritional base and an appealing scent and flavor direction.

ISO Fish forms the background of the nutritional concept, while sweet flavor enhancers and active attractors provide the distinctive character of ISO Sweet.

This makes ISO Sweet interesting for carp anglers who like to fish with sweet boilies but also value high-quality ingredients and bait suitability for long-term use.

A complete food-source boilie

Mainline developed ISO Sweet as a complete food-source boilie. This means the formula is not solely focused on a strong scent or flavor but also on providing a high-quality food source for carp.

The Dedicated Shelf Life range uses carefully composed base mixes with high-quality nutritional ingredients, complex fish meals, and easily digestible components.

According to Mainline, this composition is designed to maintain the nutritional value and attractiveness of the bait even during long-term use. This allows you to use ISO Sweet during a short session or within a feeding strategy where you consistently feed with the same boilies over several days or weeks.

Sweet attractors and powerful flavor enhancers

The recognizable character of ISO Sweet is formed by a combination of sweet flavor enhancers and attractive components. These complement the nutrient-rich base mix and give the boilie its specific sweet profile.

Mainline has formulated it so that the scent and flavor components are not only interesting during longer sessions but can also release attractive signals immediately after casting.

For carp anglers who prefer sweet bait profiles, ISO Sweet offers an appealing choice. The nutritional background also makes the boilie suitable for broader applications than just instant fishing.

Water-activated attractors for immediate effect

An important feature of Mainline ISO Sweet is the presence of attractors that are actively released upon contact with water. As soon as the boilies reach the feeding spot, soluble nutrients and scent and flavor components can spread into the surrounding water.

This creates a feeding signal around the offered bait. According to Mainline, ISO Sweet is developed to combine this immediate attraction with an effect that remains interesting over a longer period.

This feature makes the boilie suitable for various carp fishing methods, from a compact feeding spot during a short day session to a larger feeding area maintained over several days.

High-quality ingredients and good digestibility

Mainline Dedicated Shelf Life boilies are developed from a combination of nutritional value and digestibility. The base mixes used contain carefully selected ingredients tailored to the nutritional character of the bait.

In ISO Sweet, these properties are combined with sweet attractors. This results in a boilie developed not only to attract attention in the short term but also suitable for regular use as a food source.

This is especially important if you want to feed with the same boilie over a longer period. A nutrition-focused formula fits well with a strategy where carp repeatedly encounter the same bait.

More than thirty years of Mainline experience

The development of ISO Sweet builds on over thirty years of Mainline’s experience in researching, testing, and producing carp bait.

During this time, the brand has developed several well-known boilie ranges, including Cell, Essential Cell, and ISO Fish. With ISO Sweet, Mainline expands the Dedicated Shelf Life range with a sweet variant based on the nutritional background of ISO Fish.

The result is a modern carp boilie where the quality of the base mix and the effect of the attractive additives are central.

Suitable for instant fishing

Mainline ISO Sweet is especially interesting for instant fishing. When you start fishing without an extensive pre-baiting period, you want the boilies to release attractive components quickly.

Thanks to the water-activated attractors, ISO Sweet is developed to spread feeding signals immediately after contact with water.

You can, for example, feed a limited amount of boilies around the hookbait to create a compact feeding spot. This approach can also be interesting during mobile carp sessions where you regularly change spots.

The combination of immediate attraction and a nutrition-focused composition makes ISO Sweet versatile.

Especially suitable for long-term feeding campaigns

Besides immediate attraction, ISO Sweet is developed for long-term use. The high-quality nutritional base makes the boilies suitable for carp anglers who want to feed consistently with the same bait over several days or weeks.

A feeding campaign is about regularly offering a recognizable food source. By letting carp encounter the same boilies multiple times, you can try to build a fixed feeding spot.

The generous 5 kg pack fits well with this way of fishing. You have enough boilies to carry out multiple feeding sessions without needing new smaller packs each time.

Always adjust the amount of bait to the water temperature, the fish present, and the actual bait activity.

Year-round usable carp boilie

ISO Sweet is part of a bait range that Mainline considers suitable for use in all seasons. Thanks to the combination of nutrient-rich ingredients and water-activated attractors, the boilie can be used within various seasonal feeding strategies.

In spring and summer, you can use ISO Sweet during active feeding periods. In autumn, the nutrition-focused composition is interesting for regular feeding.

ISO Sweet can also be used during colder months. When carp are less active, it’s wise to feed smaller amounts and fish targeted spots where the fish are holding.

Available in 10mm, 15mm, 18mm, and 20mm

Mainline ISO Sweet Boilies come in four different diameters, allowing you to match the size to your feeding strategy and water conditions.

• 10mm: Ideal for compact feeding, subtle presentations, and offering many small bait particles.
• 15mm: Versatile size for instant fishing and smaller feeding spots.
• 18mm: Suitable for regular carp sessions and various feeding strategies.
• 20mm: Interesting for anglers who deliberately want to feed larger boilies.

Your choice of diameter depends, among other things, on the whitefish present, rod pressure, and the amount of bait you want to offer.

Combine ISO Sweet with matching Mainline bait products

Mainline has developed several complementary bait products within the Dedicated range that match the boilies. This allows you to combine multiple types of feed and hookbait within the same bait approach.

The additional range includes, among others:

• Dedicated Hookbaits
• Dedicated Groundbaits
• Dedicated Pellets
• Dedicated Particles
• Dedicated Liquid Additives and Enhancers

With these products, you can create various feeding strategies. For example, combining boilies with pellets or using a matching hookbait over a feeding spot with ISO Sweet.

Suitable liquids can also be used to add extra attraction to the offered feed. Always choose products that fit the desired bait presentation.

5 kg Shelf Life boilies for longer sessions

This version of Mainline ISO Sweet consists of durable boilies, also called Shelf Life boilies. They are developed to be stored without freezing, provided the prescribed storage conditions are followed.

The 5 kg pack is especially interesting for carp anglers who feed regularly, plan longer sessions, or want to maintain multiple feeding spots.

It’s also convenient to have enough bait available during multi-day carp sessions. The durable version also makes it easy to take the boilies along without relying on a freezer.
