Description
🌊 The Shirt That Gets You
Made from ultra-soft 100% ring-spun Softstyle cotton, because if you're going to move at manatee speed, you might as well be comfortable doing it. Lightweight, breathable, and true to size — with a tear-away label so nothing itches while you drift through your day. Printed, packaged, and shipped in the USA by people who also believe slow and steady is a lifestyle. (Sport Grey is a 90/10 cotton-poly blend — that's what makes it grey.)
Size & Fit
| Size | Chest Width | Length | Sleeve |
|---|---|---|---|
| S | 18"45.7 | 28"71.1 | 16.75"42.5 |
| M | 20"50.8 | 29"73.7 | 17.88"45.4 |
| L | 22"55.9 | 30"76.2 | 19.13"48.6 |
| XL | 24"61.0 | 31"78.7 | 20.38"51.8 |
| 2XL | 26"66.0 | 32"81.3 | 21.63"54.9 |
| 3XL | 28"71.1 | 33"83.8 | 22.75"57.8 |
Chest width — lay the tee flat, measure armpit to armpit. Double it for your full chest.
Length — from the highest point of the shoulder straight down to the hem.
Sleeve — from the center of the back neck, along the shoulder, to the sleeve end.
Easiest way: grab the tee you already love, lay it flat, and match the numbers. Runs a touch trimmer than an old boxy tee — between sizes? Drift up. Nothing in the Society is tight.
Washing Instructions
How to Not Ruin Your New Favorite Shirt:
- Cold water only (manatees like warm water — your shirt doesn't)
- Turn it inside out before washing — protect that graphic you're going to wear until it falls apart
- Gentle detergent, gentle cycle. This shirt lives a gentle life.
- First wash might bleed a little, so keep it away from your fancy stuff
- Tumble dry low or hang dry (air drying = more time for floating)
- No bleach, no fabric softener, and never iron directly on the print — inside out with a pressing cloth if you must
Shipping & Returns
Your Order Doesn't Drift.
Free shipping on orders over $75 — the Society takes care of its own.
Orders ship within 7 days, then USPS takes 2–5 days. You’ll get a tracking number so you can follow along obsessively or forget about it completely — we support both approaches.
Returns: The “Something Went Wrong” Policy
We want you to love your shirt. If it arrives damaged, defective, or just plain wrong, we’ll make it right — that’s on us.
- Damaged or defective? Full refund, no questions asked.
- You have 30 days from purchase to let us know
- Item needs to be unused and in the condition you received it
- Email us at support@manateesociety.com — we’re actual humans who respond
No faceless corporation here. If something’s wrong, just reach out — calm waters, no drama.
Policy subject to change, but we’ll always keep it reasonable.
