Quick answer

Pick https://drinkhiyoes.com/products/strawberry-guava-4pk-1-4fdbaac9bace793f9419ec8e-1309487Strawberry Guava if you want a softer, rounder fruit profile and a lower-commitment way to try a tropical Hiyo. Pick https://drinkhiyoes.com/products/passion-fruit-tangerine-4pk-1-13178c49c3702b44e3b143b4-1309483Passion Fruit Tangerine if you want a brighter, more citrus-forward lift. Both are non-alcoholic seltzers built on adaptogens, nootropics, and botanicals, so the real decision is flavor direction and pack size, not function.

If you are weighing Strawberry Guava against Passion Fruit Tangerine, the honest answer is that they sit at opposite ends of the same tropical idea. One leans soft and mellow, the other leans bright and zesty. Neither is objectively better, and the catalog does not give us sweetness or carbonation numbers, so taste direction is the deciding factor.

This comparison sticks to what is actually documented about the two flavors and the surrounding Hiyo lineup. You will get a clear pick for each drinker type, plus the format and gear details that quietly shape which one you should actually order first.

What each flavor is actually going for

Strawberry Guava is described by Hiyo as a light, playful ode to summertime, with refreshing watermelon finished by a crisp hint of lime. That is a soft, rounded profile: fruit first, citrus as a quiet accent rather than the headline. If you usually reach for berry-forward or melon-forward drinks, this is the more natural starting point of the two.

Passion Fruit Tangerine is the brighter side of the same tropical family. Where guava reads mellow, passion fruit and tangerine read zesty and citrus-driven. Hiyo does not publish sweetness, carbonation, or caffeine figures for either flavor, so treat any claim about exact intensity as a guess. What the catalog does support is the direction: one is softer, one is sharper.

  • Choose by direction, not by ranking: soft and fruity versus bright and citrusy.
  • If you already know you dislike tart, citrus-forward drinks, start with Strawberry Guava.

The shared formula behind both flavors

Both flavors are non-alcoholic seltzers and both are built with stress-relieving, mood-boosting adaptogens, nootropics, and botanicals. Hiyo calls the resulting feeling "the float." That shared base matters for this decision: you are not choosing between a functional drink and a plain one, you are choosing between two expressions of the same functional formula.

Because the functional side is identical, flavor is the only real variable. That simplifies things. If you have tried one Hiyo flavor and liked the effect, the question becomes purely whether you want your next can to taste softer or brighter.

  • Same functional premise in both flavors, so let taste decide.
  • If you are new to the brand entirely, a smaller pack is the cheaper way to test your preference.

Pack size changes the risk of trying a new flavor

Hiyo lists Watermelon Lime in two formats: a 4-pack and a single-can option. That distinction matters more than it sounds. A single can is the low-risk way to find out whether a flavor direction suits you, while a 4-pack makes sense once you already know you like it and want it on hand.

The same logic applies when you are comparing Strawberry Guava against Passion Fruit Tangerine. If you are torn, do not buy a large format of either. Start small on the one whose description appeals more, then commit once your own taste confirms it.

  • Start with the smaller format when the flavor is unproven for you.
  • Buy the larger pack only after you have finished one and wanted a second.

Where the merch fits into a flavor order

Hiyo also sells apparel and accessories alongside the drinks, and a few of them pair sensibly with a seltzer order. The hiyo dad hat is unstructured cotton with a soft crown lining and an adjustable brass buckle, which makes it the more relaxed of the two hats. The hiyo trucker hat uses a firmer cotton and poly blend with a seamless front panel and plastic snaps, so it holds its shape more aggressively.

If you are ordering drinks anyway, the what's inside matters tote is a 12 oz. cotton canvas bag at 20 by 14 by 7 inches with a 6-inch drop handle. It is the kind of item that makes a drink order feel like a full restock rather than a single add-on. None of this changes which flavor you should pick, but it does change what a first order looks like.

  • Pick the dad hat for a soft, low-structure fit; the trucker hat for a firmer crown.
  • The tote is sized for groceries and everyday carry, not just merch.

The trade-offs, plainly

  • Flavor direction: Strawberry Guava reads soft, round, and fruit-forward with lime as a background note. Passion Fruit Tangerine reads brighter and more citrus-driven. Hiyo does not publish sweetness or carbonation numbers for either. Choose the softer option if tart drinks wear on you; choose the brighter one if you want a sharper lift.
  • Commitment level: Watermelon Lime is listed in both a 4-pack and a single-can format, so the brand clearly supports trying before committing. A single can costs less to get wrong than a full pack. If you are undecided between the two flavors, buy the smaller format first.
  • Merch pairing: The dad hat is unstructured cotton with a soft lining and brass buckle; the trucker hat is a firmer cotton/poly blend with plastic snaps. The tote is 12 oz. canvas at 20" x 14" x 7". Let fit preference decide the hat, not the flavor you picked.

Catalog facts worth knowing

  • watermelon lime: Non-alcoholic watermelon lime seltzer with a crisp hint of lime, crafted with stress-relieving, mood-boosting adaptogens, nootropics, and botanicals; listed at USD 44.99 for the 4-pack and USD 22.50 for the single-can option. The two formats let you test a flavor cheaply before committing to a larger pack.
  • hiyo dad hat: Unstructured, durable cotton with a soft crown lining, 58cm / 22.8in diameter, six-panel, curved visor, adjustable sliding clasp with a brass metal buckle. The unstructured build and soft lining suit anyone who finds stiff caps uncomfortable.
  • hiyo trucker hat: Firm and structured cotton/poly blend (35% cotton / 65% polyester), 58cm / 22.8in diameter, five-panel, curved visor, adjustable plastic snap clasp. The structured front panel keeps its shape, which reads dressier than the dad hat.
  • what's inside matters tote: Softly structured 12 oz. cotton canvas tote, 20" x 14" x 7", with woven straps sewn along the rim and a 6" drop handle. The dimensions and drop handle make it practical for groceries and daily carry.

Which one should you actually buy?

Best for

  • Drinkers who prefer soft, fruit-forward flavors over sharp citrus
  • Anyone trying Hiyo for the first time and wanting the gentler of two tropical directions
  • Buyers who want a smaller format before committing to a full pack

Not for

  • Drinkers who want a bright, zesty, citrus-led seltzer
  • Anyone who already knows they dislike melon or berry-style fruit profiles
  • Buyers who want a large-format pack on the first order

There is no universal winner here, only a direction. Go soft and fruity with Strawberry Guava, or bright and citrusy with Passion Fruit Tangerine, and start with the smaller format so your own taste makes the final call.
