Heavyweight Long Sleeve Size Guide
Our heavyweight long sleeve is printed on the Bella+Canvas 3511 — a substantial 6 oz, 100% Airlume cotton tee with a relaxed, boxy cut. It wears a touch oversized on purpose. Love a closer fit? Size down one.
Size Chart
Measurements are in inches. “To fit chest” is your body measurement; “garment width” is the tee laid flat, measured pit-to-pit (one layer).

How to Measure
The easiest way to nail your size is to measure a long-sleeve tee you already love and compare it to the chart above.
Chest: Lay the shirt flat and measure straight across from underarm to underarm (pit-to-pit). That's the “garment width” column.
Length: Measure from the highest point of the shoulder down to the hem.
Sleeve: Measure from the center back of the neck, across the shoulder, and down to the cuff.
A Note on the Fit
This is a heavyweight tee with a relaxed, boxy cut — a little wider and a little shorter than a standard fitted long sleeve. That easy, slightly oversized drape is the look it's made for, and it layers beautifully over a tee or under a jacket.
If you prefer a closer, more tailored fit, size down one. If you love that roomy, throw-it-on feel, stick with your usual size.

Description
Kept Its Needles
Everything else in the garden went bare. The pine is still holding the moon up.
A crescent moon caught in the cloud-pruned tiers of a Japanese pine, drawn in cream ink on a dark ground the way the old woodblock printers did it: one color, no shading, the needles stacked in rounded pads and the trunk twisting up through them. In Japan the pine is the tree of long life because it keeps its needles through winter while the maples and cherries let go, and the moon in its branches is one of the oldest pairings in the country's art. This one is quiet enough to wear on a Tuesday.
Printed large on the chest in a single cream tone. No text anywhere in the design.

The colors
Navy is the night sky the design was drawn for; the cream moon glows against it. Forest reads like the pine itself, with the print sitting a little softer on the green. Two colors, both dark, both with women's and men's photos.
Fit
Relaxed and roomy with a dropped shoulder. Most people take their usual size; size down for a closer fit. S to 2XL.
Pairs well with
The rest of this week's long sleeves are in New Arrivals, and the heavier layer for a cold night is in Sweatshirts.
Care Instructions
A little care keeps the color true and the artwork sharp for years.
Machine wash cold, inside out, on a gentle cycle.
Tumble dry low, or hang to dry.
Mild detergent. No bleach, no fabric softener.
Don’t iron directly over the artwork. If you must press it, turn it inside out and use low heat.
About that faint square. On printed pieces, fresh out of the box you may see a pale square or ring around the design. It’s the mark of the heat press that cures the print, and it washes out completely the first time through the machine.
Hats: spot clean with a damp cloth; don’t machine wash.

Return Policies
Everything we sell is made to order — this piece didn’t exist until you ordered it. That’s why we ask you to check the size guide first, and why we’d still rather fix a problem than argue about one.
Not sure about size? Check the size guide linked above the size picker, or email hello@knownpack.com with your usual size and we’ll point you to the right one.
Wrong size or changed your mind. Unworn, unwashed items can be returned or exchanged within 30 days of delivery. Email us with your order number and, for an exchange, the size you need, and we’ll send instructions. Once the return arrives we ship the new size or refund your original payment method; refunds usually appear within 5–10 business days. Return shipping is the customer’s responsibility.
Holiday orders. Anything ordered November 1 – December 24 can be returned or exchanged through January 31, 2027. Gift recipients can exchange too; they just need the order number or the name on the order.
Damaged, defective or wrong item. Email us within 30 days with your order number and a photo. We’ll remake it or refund it, your choice, and you don’t send anything back.
How to start. Email hello@knownpack.com with your order number, the email you used at checkout, and what happened. A real person replies, usually the same business day.

FAQs
When will it arrive?
Free standard shipping on every U.S. order, no minimum. Each piece is made to order: production takes 2–5 business days, then 3–7 business days in transit. Plan on one to two weeks door to door. For Christmas delivery, order by December 10.
What’s the fit like?
A relaxed unisex fit that runs true to size. Most people take their usual size; for a closer fit, go one size down. Measurements are in the size guide linked above the size picker.
Will it shrink?
Very little. Comfort Colors pieces are dyed and washed after they’re sewn, so most of the shrinkage has already happened before you get it, and our long sleeves are pre-shrunk combed cotton. Wash cold and dry low and it keeps its shape; a hot dryer is the only thing that will tighten it up.
I ordered the wrong size. What now?
Email hello@knownpack.com with your order number. If it hasn’t gone into production yet, we’ll change it. If it has, unworn, unwashed items can be returned or exchanged within 30 days of delivery: send us the size you need and we’ll send return instructions. Holiday orders placed November 1 – December 24 can be exchanged through January 31.
How soft is it, really?
Soft on day one and softer with every wash, without going thin. Garment-dyed pieces arrive already broken in; the heavyweight long sleeves arrive with a little structure and relax over the first few washes.
Beautiful things from the natural world, on a long sleeve you'll reach for all season long.

Heavyweight Airlume Cotton
Bella+Canvas 3511: six ounces of combed, ring-spun cotton in a relaxed, boxy cut. Dense enough to wear as a light layer, soft enough to live in.
Store owner replied:
Thank you, Nancy - so glad the poppies made it to you quickly and that the fabric lived up to it. The Comfort Colors cotton only gets softer from here. Please enjoy it!
Max, The Known Pack
Love the soft all cotton and the beautiful design! The t-shirt is so comfortable!
Store owner replied:
Thank you, Janette! We love that cotton - it keeps getting softer every wash, so it should only get better from here. Glad you’re enjoying it.

It’s a Christmas present for my sister so time will tell.
Store owner replied:
Thank you, Marian! A wildflower wreath is such a beautiful and thoughtful choice for a sister. We hope she absolutely loves it and that it makes her smile!
Honestly, I just really like the message. I overthink a lot, so it’s a nice little reminder to give myself more credit.
The bay color is really pretty and goes so well with the butterfly and floral design. The artwork has a lot of little details that look even nicer in person. The shirt is soft and comfortable, and the fit is just the way I like it.
I absolutely love this sweatshirt! The butterfly design is beautiful and has such a cool vintage feel. It’s soft, cozy, and comfortable for everyday wear. The relaxed fit and muted colors make it easy to style. Really happy with it!
The sweatshirt has a nice weight to it and feels comfortable without being stiff. The tiger is really detailed and I like how the bamboo and magnolia frame the design. I went with my usual size and it fits roomy.
The butterfly print is really pretty and there are a lot of little details in the flowers. Shirt is soft and comfortable. It looks nice with jeans and I’ve already worn it a few times
Bought this for my girlfriend and she really liked it. The blue butterfly is beautiful and the colors look even better in person. She said it’s really comfortable and the relaxed fit works well. Definitely glad I picked this one.
Really love the flower bouquet on this one. The little butterflies are a sweet detail, and the whole design feels cheerful without being too much. Just my kind of shirt.
Picked this out for my stepmom’s birthday. The wildflowers and little butterflies are so pretty, and the design felt like something she would enjoy. A sweet find that made choosing her gift a little easier.
Nice quality shirt and the bee/sunflower design is very well done. I ordered the darker color and the artwork shows up really nicely against it. Fits good and the fabric feels substantial.
Ordered this because of the flowers and butterfly and it turned out really pretty. The artwork has a softer look in person. Comfortable shirt and the size was right for me.
Really like this tee. The Luna moth and moonflower design looks even better in person, and the shirt is comfortable without feeling too heavy. The fit is pretty good and it washes well so far. Definitely a nice addition to my wardrobe.
This has a different look than most of the celestial shirts I’ve seen. I like the folk-art style and all the little details around the sun and moon. The shirt itself is comfortable and the print looks good.
The front is pretty simple, but the back is what really caught my attention. I like all the little details in the sun, moon, and flowers, and the design has a nice vintage feel to it. The shirt is soft and comfortable, and the fit is relaxed like I expected. The print looks really good in person too.
My daughter received the shirt the other day (I had ordered it for her as a surprise). She loved the color and she loved the texture. (she also loves butterflies). Said it was so soft
Thanks.
Store owner replied:
Thank you, MaDonna! A surprise gift for a daughter who loves butterflies, that is exactly why we make these. So happy it arrived soft and landed well. Please enjoy.

I like the shirt overall. The design looks nice and it’s pretty comfortable, although the fit was a little different than I expected. The material is decent and I’ve worn it a few times already. I’m happy with it.
Such a cute and comfortable tee! I love the simple design and the message feels so positive without being over the top. The fabric is soft and it fits really nicely. It’s one of those easy everyday shirts I know I’ll be wearing a lot.
Good everyday long sleeve. The fabric has some weight to it but it’s still comfortable for layering. I like the message on this one and the relaxed fit worked well for me.
Really nice shirt. The design is pretty and I like the message without it feeling too over the top. The fabric is soft and the fit is comfortable and a little relaxed. I got the Chambray color and the flowers and butterflies look really nice against the blue. It’s an easy everyday shirt and I’ve already worn it a few times.
Store owner replied:
Pamela, thank you! This made our whole day. The Monarch is the design that started it all for us, so hearing that the fit, the color, and the butterfly all landed perfectly is everything we hope for. Thank you for supporting our small shop. Max & Anya, The Known Pack
