What's in the Berry Burst TREK bar?

Think trail snack first, protein bar second: dates and raisins form the base, gluten-free oats add chew, and freeze-dried raspberries bring that tart pop.

Protein comes via crisp soy pieces—light and crunchy instead of dense—while additives stay minimal, with a little tapioca starch to hold the crisps and rice starch plus natural flavorings to keep the berry notes consistent.

Macros lean toward quick energy: higher carbs and sugars, very low fat, and modest protein. The sweetness comes entirely from fruit, including apple, pear, and grape juice concentrates—flavors your tongue reads as fruit, but sugars your body absorbs quickly.

What are people saying?

Main praise: Reviewers love the clean, fruit-led flavor and crunchy soy texture—no artificial aftertaste, easy to grab-and-go, and reliably tasty on the move.

Main criticism: The macro math turns some shoppers off: roughly 10g of protein alongside about 25g of sugar feels more like an energy bar, with occasional notes about dryness and value.

Bottom Line

Best for pre-run or mid-hike fuel, or anyone who prefers plant-based, fruit-derived sweetness and a light, crunchy texture without sugar alcohols. Less ideal if you’re chasing 20g of protein or minimizing sugar.

What's in the Lemon Coconut SimplyProtein bar?

Bright lemon meets toasty coconut in a plant-based bar built on soy protein crisps. Those crisps—soy protein isolate lightly bound with tapioca—deliver complete vegan protein while keeping the texture light and snappy.

Energy comes from oats and brown‑rice crisps, steadied by chicory root fiber, with fats kept modest via cashew butter, sunflower oil, and a sprinkle of coconut. Sweetness leans on a small amount of cane sugar, rounded out by vegetable glycerin (a plant‑derived syrup that keeps bars moist) and natural flavors.

The result is a gluten‑free, dairy‑free bar with mid‑pack protein and very low sugar—more crisp snack than candy‑bar clone.

What are people saying?

Main praise: Fans love the crisp, airy texture and the restraint—13g of vegan protein, very low sugar, and no stevia or sucralose—with a bright lemon‑coconut flavor that plays well with coffee.

Main criticism: Detractors call it dry or powdery and find the lemon coconut flavor polarizing, and a few sensitive stomachs don’t love the chicory root fiber and glycerin.

Bottom Line

Choose it if you want a light, crunchy, plant-based snack between meals or a gentle post‑workout bite with a citrus twist—and you prefer low sugar without high‑intensity sweeteners. Skip it if you avoid soy or tree nuts, or if you want a dense, brownie-like protein bar.

What's in the Cookie Dough PROBAR bar?

PROBAR's Cookie Dough leans into the name: almond butter for doughy chew, real chocolate for the 'chips,' and cane sugar plus tapioca syrup with a hint of molasses for brown-sugar warmth.

The protein backbone is soy protein isolate, which puts this bar toward the top of the aisle for both protein and carbs, so it is more energy-forward than minimalist. Fats from cocoa butter, palm kernel and safflower oils, and almonds add softness and flavor without a heavy fat load.

You will also see three common functional helpers: vegetable glycerin (a plant-derived moisture holder), soluble tapioca fiber (a refined resistant fiber), and lecithins from sunflower and soy (emulsifiers) used in small amounts to keep the bar chewy and cohesive.

What are people saying?

Main praise: Fans rave about the taste, calling it candy bar-like, and they appreciate the 20g of complete plant protein with no sugar alcohols.

Main criticism: The tradeoff is sweetness and texture: 15g of sugar and a dense, sometimes dry bite, plus soy and almond allergens that limit who can enjoy it.

Bottom Line

Plant-based eaters and sweet-tooth athletes who want dessert-like fuel for pre/post-workouts or a satisfying afternoon pick-me-up—assuming soy works for you.

What's in the Chocolate CLIF bar?

This bar doesn’t make you choose between flavor and function: it packs 20g of soy‑based protein beneath a real chocolate profile built from unsweetened chocolate and cocoa. The sweet side is not shy—31g of carbs with 17g of sugar—driven by cane syrup and cane sugar (concentrated sugarcane) plus brown rice syrup, which your body absorbs quickly.

Nine grams of fat from palm kernel oil, seed oils, and cocoa butter give a smooth, creamy bite. It’s plant‑based and gluten‑free, and it’s built more like performance fuel than a minimalist whole‑foods bar.

What are people saying?

Main praise: Reviewers consistently rave about the chocolatey, crunchy taste and the staying power of 20g of complete soy protein—plant‑based, gluten‑free, and genuinely satisfying.

Main criticism: The downsides are the higher sugar and calories, a more processed ingredient list (including palm kernel oil), and a texture some find dense in cooler temps.

Bottom Line

Best for post-workout recovery, long hikes, or any day you need a substantial, chocolate-forward refuel. Less ideal if you’re aiming for a lower-sugar, low-carb snack.

What's in the Sweet & Salty Caramel Peanut Crisp KIND bar?

KIND's Sweet & Salty Caramel Peanut Crisp starts with what you taste first: real peanuts, a clean hit of sea salt, and a caramel profile built without a syrupy sugar base.

The 20g of protein comes mostly from soy protein isolate, a complete plant protein, with a bit of milk powder and peanut protein along for the ride.

Sweetness and chew rely on allulose, a low-calorie sugar that tastes like sugar, plus soluble fibers from tapioca and chicory, with a little tapioca starch to keep those crisp bits intact.

Palm kernel oil helps the bar hold its shape - more of a saturated fat - balanced by the mostly monounsaturated fats found naturally in peanuts. You'll also see a short list of functional helpers, about three additives, like lecithin to keep things blended and vitamin E to protect the oils.

What are people saying?

Main praise: Reviewers rave about the salty-sweet, real-peanut crunch and the lack of chalky protein aftertaste, with strong ratings to match the 20g of protein.

Main criticism: Sensitive stomachs report rumbling from chicory fiber and allulose, and some find the texture too hard or the ingredient list too engineered, palm kernel oil included.

Bottom Line

Best for peanut lovers who want a high‑protein, low‑sugar, crunchy bar for post‑workout or an afternoon hold‑you‑over—especially if you do well with chicory root fiber and allulose. Skip if you avoid soy, dairy, or peanuts, or if you’re sensitive to added fibers.
