MANCHESTER — The American Red Cross is joining forces with positive lifestyle brand Life is Good to invite donors to show the power of doing good by giving blood.

Those who come to give blood or platelets from March 30 to April 12, will get an exclusive Red Cross x Life is Good T-shirt, while supplies last. See RedCrossBlood.org/LifeIsGood for details.

“Life is Good has always been about more than a T-shirt; it’s a reminder that the world is full of good worth fighting for, and that spreading optimism starts with the everyday choices we make,” said Linne Kimball, vice president of strategic partnerships for Life is Good. “For us, partnering with the Red Cross was a natural fit, because giving blood is proof that one person and one simple act can make a real difference. We hope this collaboration inspires donors old and new to turn positivity into purpose ─ because doing good doesn’t have to be complicated, sometimes all it takes is rolling up a sleeve.”

Between spring break plans and the return of outdoor activities, busy spring calendars can impact the availability of lifesaving blood products — but the need for blood never stops.

“It’s critical that donors make and keep appointments in the weeks to come to help the blood supply stand up to any seasonal disruptions or challenges,” said Paul Sullivan, senior vice president of donor services for the Red Cross. “The Red Cross is grateful to Life is Good for joining us in an important mission ─ sparking optimism and kindness through blood donation.”

Reserve a spot to donate blood or platelets by visiting RedCrossBlood.org, downloading the Red Cross Blood Donor App or calling 1-800-RED CROSS.
