Teacher tumbler

Carla is a teacher and talks all day — she keeps a 36oz Limitless next to her. Lori wrote that as a teacher, a 15oz that keeps coffee hot is priceless. Jennifer is a teacher who uses the 20oz Tumbler so coffee is still hot when she gets back to it. The Reader is sold out; Dying To Read is in stock. Art designs live on gifts for art lovers. Teachers get 15% off through GovX. Gift ideas beyond the bottle: Gifts for teachers that don't suck.

157 designs in stock. The Reader is sold out. Dying To Read is in stock on the 15oz, 24oz and 20oz Tumbler.

In the classroom

Talk all day. Coffee still hot.

We quote teachers. We do not invent a class-period hour test.

  • A bottle next to the talking

    Carla is a teacher and talks all day. She wrote that a cold drink is always available. Toni is a teacher returning to school. Cassie is a teacher who loved the design. We do not make a 40oz — Carla's title said 40oz; she reviewed the 36oz.

    I am a teacher and talk all day.

  • Coffee that is still hot

    Lori wrote that as a teacher this is priceless. Jennifer is a teacher: coffee goes cold in an hour in a mug. The 20oz Tumbler is up to 13+ hours* hot. It is final sale. The sliding lid is splash-resistant, not leakproof.

    ★★★★★

    As a teacher this is priceless!

  • Ice left in a classroom overnight

    Adrian left a tumbler in a classroom overnight and still had ice the next morning. That is one 2018 review. The rated spec is up to 20+ hours* cold on the tumbler, up to 36+ hours* on a Limitless.

    ★★★★★

    I accidentally left it in my classroom over night and when I returned the next morning there was still ice in it

  • The gift list is already written

    Sarah gave a 24oz to her daughter's teacher. Joseph bought one for his son's teacher. Higinio bought The Reader for an English teacher. The longer list is Gifts for teachers that don't suck — we do not copy it here.

Book and art

The Reader. Art they can carry.

Feature the designs. Do not rebuild those catalogs.

  • The Reader is sold out

    Amy bought The Reader for her daughter, the reader of the family, a teacher who loved the design. Higinio bought it for an English teacher. The Reader is sold out. Dying To Read is in stock. The book page is gifts for book lovers.

    I bought The Reader for my daughter who is the “The Reader” of our family! … She is a teacher and loved the design

  • Art designs are a separate page

    Pink Peach Tree, Irises, Garden at Arles and the rest live on gifts for art lovers. Those are COLDEST designs, not licensed museum prints. We do not repeat that catalog here.

Do you make a 40oz teacher tumbler?
No. Carla's review title says 40oz. She reviewed the 36oz. Pick 36oz or 46oz.
Where is the longer teacher gift list?
Gifts for teachers that don't suck is the gift post. This page is the bottle. We do not copy that list.
Do teachers get a discount?
Yes. Teachers and educators get 15% off after verifying through GovX: the frontline discount.
Why is there no classroom photo?
The only teacher photo review is the same classroom paragraph posted on three products. The checker refuses duplicate text. Packshots are The Reader, Dying To Read and art.

Stock and the rest

Do sold-out designs come back?
Most COLDEST designs are a single limited run. A few have come back in a new size. We never promise a restock. Sign up for restock alerts on the product page if you want an email when that size returns.
How do I hear if a sold-out size returns?
Open the product page for that size and sign up for restock alerts there. That is an alert, not a promise.
Can I still get a retired design?
Some retired designs appear in the Mystery bottle pool. The published odds are on the Mystery product page. No specific design is guaranteed.
When do new limited designs come out?
New limited designs show up on Latest Drops when they launch. We do not publish a drop clock on this page.

The Chug and Sports lids are 100% leakproof when closed. The Sip straw lid can leak if tipped. The 20oz Tumbler sliding lid is splash-resistant, not leakproof.

No. We make 15oz, 24oz, 36oz and 46oz Limitless, plus the 20oz Tumbler, the 30oz Drive Thru, the 32oz GO and the 128oz Gallon. For a 40oz-class drink, pick 36oz or 46oz.
