Pros
- Outstanding all-day protection, an EPA-label 10 hours on mosquitoes and 7 to 8 on ticks from 20% picaridin.
- Lotion with a glycerin base that rubs in clean and light, none of DEET's grease, and safe on plastics and gear.
Cons
No significant downsides for its role.
The full review
An odorless 20% picaridin lotion, this is one of the strongest recommended, maximum protection options in the lineup. Its protection times come straight off the EPA-registered label, an exceptional 10 hours of complete mosquito protection and 7 to 8 against ticks, which drives an effectiveness pillar that is high even by DEET standards and remarkable for a DEET-free formula. Picaridin's evidence is settled, safety reads clean apart from a minor aquatic-toxicity note, and 5 of 6 audited claims hold up strong. The lone drag is a transparency ding, since the brand discloses its actives in full but quantifies only a fraction of the rest. The glycerin-based lotion suits targeted use on the face and neck, rubs in light, and being DEET-free it stays safe on gear.

Effectiveness45%100Mosquitoes: 10 h of complete protection. Ticks: 7–8 h of complete protection. Protection times come from the product's EPA-registered label (a manufacturer maximum, capped to a defensible ceiling). Scored on a saturating curve (each added hour counts less than the last), 65% mosquito / 35% tick, with reasonable confidence.

How long it protects
Complete protection ends when the first bite gets through; partial protection keeps reducing bites as repellency decays. EPA label times are verified; the rest are modeled from the actives, concentration, and format.
Mosquito estimate basis (moderate confidence)
From the product's EPA-registered label (manufacturer maximum against mosquitos, treated as an upper bound). The label's "up to 14 h" is a maximum; we cap it at 10 h for this active class as a defensible complete-protection estimate. Partial protection (reduced but real bite suppression) is modeled to extend to ~18 h as repellency decays.
Tick estimate basis (moderate confidence)
Estimated complete protection time from active ingredient + concentration; the source research used a spray-style formulation, matching this lotion (no format adjustment). Partial protection (reduced but real bite suppression) is modeled to extend to ~14 h as repellency decays.

Claims audit
What the marketing says, versus what the evidence supports.
“TSA-approved 3.4 oz travel size”
OtherStrongA 3.4 oz bottle meets the TSA carry-on liquid limit — a verifiable format fact.
“Scent-free, non-oily, non-greasy”
OtherStrongPicaridin is widely characterized as odorless and the lotion's inerts (water, glycerin, carbomer) support a non-oily, non-greasy feel.
“DEET-free formula”
Deet FreeStrongActive is picaridin; contains no DEET.
“Up to 8 hours of protection against biting flies, gnats, and chiggers”
DurationStrongStandard EPA-approved secondary-pest duration for 20% picaridin products.
“Up to 14 hours of protection against mosquitoes and ticks”
DurationModerateRe-evaluated against our corrected complete-protection estimate (~10 h): the claimed 14 h is 1.4× our estimate, so this duration claim is optimistic but plausible (a label maximum).
“Picaridin 20%”
EfficacyStrongConfirmed on the manufacturer's spec sheet; CDC-recommended active ingredient.
How to apply it
Apply enough lotion to cover exposed skin evenly and rub in; for the face, dispense into hands and spread, avoiding eyes and mouth. Do not apply over cuts, wounds, or irritated skin, and do not apply to children's hands; adults should apply the product to children. Reapply after the protection period ends (up to 14 hours for mosquitoes/ticks, 8 hours for biting flies, gnats, and chiggers) or after swimming, sweating, or toweling off. Wash hands thoroughly with soap and water after handling and before eating or drinking.
