Here are several long-lasting deodorant/antiperspirant options that work well for college guys — grouped by type (maximum sweat-blocking, budget-friendly, and aluminum-free/natural). Short pros/cons and quick usage tips included so you can pick what fits your schedule, activity level, and skin sensitivity.

1. Best for maximum, all-day sweat control (antiperspirant / clinical strength)

• Degree Men Clinical Strength (or Degree Advanced/Extreme 72H sticks) — strong aluminum-based formula made to control sweat and odor for long periods; good for heavy classes, sports, dorm life. Very effective at keeping you dry. (verywellfit.com)
• Certain Dri (clinical-strength roll-on) — one of the more commonly recommended clinical options if you need prescription-level control (apply at night for best results). User reports and clinical labels recommend nighttime application for maximum effectiveness.

Why choose this: If you sweat a lot or need to stay dry during long labs, workouts, or exam days, antiperspirants with aluminum salts are the most reliable.

2. Best balance of performance + skin friendliness (everyday antiperspirants)

• Dove Men+Care (sticks or sprays) — gentle on skin, good sweat and odor control, widely available and affordable.
• Every Man Jack Antiperspirant + Deodorant — tested well in recent round-ups for sweat control and being skin-friendly. (verywellfit.com)

Why choose this: Good day-to-day protection without the sting some clinical products cause; solid value for students.

3. Best if you want aluminum-free / “natural” deodorant (odor control, but you’ll still sweat)

• Native, Schmidt’s, Blu Atlas 48-Hour (natural formulations), No Pong (cream-type) — these use baking soda, magnesium, plant extracts, or absorbents to neutralize odor rather than blocking sweat. They can work very well for many people but performance varies by body chemistry; some users find natural options need reapplication or a short “adjustment” period. (allure.com)

Why choose this: If you prefer to avoid aluminum or want to let your body sweat while still controlling odor. Expect more variability in “how long” they last compared with antiperspirants.

4. Budget / easy-to-find picks for dorm life

• Old Spice or Axe sprays and sticks, Gillette Clinical/Invisible Solid, Mitchum (antiperspirant sticks) — inexpensive, easy to replace, and many formulas advertise all-day protection. Good for students on a budget. (ndtvshopping.com)

Quick tips for getting the best, longest-lasting results

• Apply to clean, dry skin. For clinical products, applying at night lets the active ingredient set in pores while you’re less active and often increases longevity.
• Don’t mix antiperspirant with strong fragrances or layering lots of cologne — that can make smells worse.
• If you’ll be active or in hot/humid environments, consider a clinical strength antiperspirant or reapplying a light spray midday.
• If switching from aluminum antiperspirant to an aluminum-free deodorant, give your body ~1–2 weeks to adjust; you may notice more sweat initially.
• If you have sensitive skin, pick “sensitive” labels (fragrance-free, low baking soda) or try patch-testing first.

My short recommendation for a college guy who wants one product that’s reliable: try Degree Men Clinical/72H stick or Dove Men+Care (for gentler daily use). If you prefer to avoid aluminum, try a top-rated natural option (e.g., Blu Atlas, Native or No Pong) but be prepared to test a couple to find the one that works with your body chemistry.
