LIGHTWEIGHT – Of course it is, we designed it with you in mind. Ideal for skiing, hiking, or recovering from a late night out. Standing tall and trim, you can cleverly slip the O+ Skinni into your ski jacket or hiking backpack. SLOW RELEASE – Our Oxygen Canisters have a “tilt-back” top that releases oxygen slowly into your mouth or nose so that you can breathe it in. WE CARE – Our oxygen canisters are designed, quality-controlled and filled in the U.S.A., the O+ Skinni is 100% recyclable after use. Oxygen Plus is the only portable recreational oxygen filled in the U.S.A. in a FDA-registered facility. SIZE – Includes 24 O+ Skinni canisters – Each Oxygen Plus O+ Skinni is 7.5 inches tall, 1.25 inches in diameter and weighs 49 grams. One canister contains more than 50 breaths (3.42L) of pure recreational oxygen for natural energy and recovery. ALL OCCASIONS – Portable oxygen is well known to restore your oxygen levels at high altitudes, but Oxygen Plus can be helpful for any active, daily task. Whether you are suffering from jet lag, working late, taking a long drive, working out or recovering from a late night out, keep an Oxygen Plus oxygen canister close by.
