Long Sleeve Pajama Set - Llama Adventures
As Featured In
Breathable comfort from bedtime to morning: the Long Sleeve Pajama Set keeps a little one at the right temperature all night, instead of waking up too warm or too cold partway through. Made from TENCEL™ Lyocell with spandex for stretch, this two-piece set actively manages body heat and sweat to reduce temperature-related sleep interruptions, which in practice means fewer overnight wake-ups tied to overheating or a sudden chill. The fabric is naturally hypoallergenic, moisture-wicking, and temperature-regulating, gentle enough for babies with sensitive skin or eczema, and soft enough that it doesn't need breaking in the way some sleepwear fabrics do. TENCEL™ Lyocell is made from sustainably sourced wood pulp using a closed-loop process that recycles water and solvents with minimal waste, so the sustainability story and the comfort story are the same fiber choice rather than a tradeoff. Flat seams and a printed inner care label prevent irritation against overnight skin contact, and the snug-fit design meets Canadian flammability standards for children's sleepwear, an important distinction from loose-fitting loungewear, which isn't held to the same safety requirement. As a two-piece set, it works as a standalone warm-weather pajama or as a base layer under a sleep bag in a cooler room, giving it use across more of the year than a single-season pajama would offer. It's Health Canada compliant and OEKO-TEX Standard 100 certified, meaning it's free of harmful substances by an independent, third-party standard rather than a marketing claim alone. Machine wash cold and tumble dry low to preserve the softness and fit over repeated washes; pajamas get washed more than almost anything else in a baby's wardrobe, and TENCEL™ is chosen specifically because it holds up to that schedule. Proudly designed in Canada, it's a genuine bedtime essential rather than a decorative pajama set, built to actually be worn on repeat.

My kids love it, they love their matching jammies, so comfy and light. We'll bring this with us when we travel as it packs light.
My daughter's favorite blankie is this same pattern. She loves that blankie so much we had to buy two so we'd have a backup. Now she needs to sleep with both of them at the same time. Of course. But we love the blankie's so much that we bought a pair of "blankie jammies" too. We also got a pair in Canyon Rainbow. Like the swaddle, we have tons of jammies - inherited from cousins and older sibling, gifts, etc - but these are the only jammies we wear. They are just the right weight, soft and thin, so she can wear them in summer w/o a sleep sack and winter with a little extra warmth or a blanket. We just upgraded to the next size. I won't bother getting any other brands. These are not inexpensive, but they wash up softer and softer, they wear well and they are worth the money. Love them.
Beautiful, comfortable. Always great products. Highly recommend.
It’s soft and stretchy, and will last a while. I wish they still sold it!
Our grandson loves trains, so this design is perfect! We appreciate the colourful, realistic scenes and soft material.
The seam at the crotch ripped after the first wash. While they are so cute and soft they are quite expensive for something the rips almost immediately. Would not repurchase from here.
We really like these pajamas! The prints that they have are so cute and whimsical. I do wish they were slightly looser in the arms. The legs seem fine but the arms are very tight. That being said, I will 100% purchase more!
Love the waffle. I find this material lasts the longest as it has more give to it.
I was looking for cute, good quality pyjamas for 3 grandchildren. I wanted gender neutral ( 2 boys and a girl). Ordering from a Canadian company is a priority. Delivery was fast and these were perfect!
So soft. So comfy. Just wish the sizing went up. Size 6 barely fit our 4 year old boys. Maybe get a month or two of wear.
Incredibly soft. My daughter loved them. I might love them more. I wish they had my size!
These pjs are so soft I want a set for myself. I got matching ones for my girls and they love them.
Soft pajamas with beautiful prints. Perfect for slim kids. I sized up. It is a bit see through, but it’s okay.
I wanted to love this as much as loved the rest of my order. The colour is washing out after a couple of washes and it looks like an old garment now.
Cute Jammies, Baby Sprinkle gift for Big Sister! She loves them!
These have a long slim fit which is perfect for my peanut and should I’m hoping to get at least two summers out of them. The fabric is so soft and washes well. All the prints are so cute too. Wish they made the Canada prints in larger sizes.
beautiful gender neutral + soooo soft and cozy. love for all seasons
I love how soft the fabric is — and even better, it’s so much more eco-friendly than bamboo rayon. I discovered TENCEL a few years ago and fell in love with it so when I found out that Loulou Lollipop makes TENCEL Lyocell sleepwear for little ones, I just had to get it! My daughter absolutely loves her jammies!
Literally the softest, most comfy jammies for my granddaughter! She just loves them, especially this beautiful new print. Two of hef favourites… pink and unicorns!
So soft!
My girls have outgrown their smaller set of these pajamas and they are still their favorite cozy pajamas… so I ordered them new sizes and they haven’t taken them off since they arrived. So soft and comfy

Love all these series. Wish they'd keep coming up with more patterns
Bought 4T for my almost 3 year old since reviews said to size up. Now it's just really long and super tight. He's sleeping in them tonight because he loves the print. But he was walking funny and tugging at his arms.
These are so cute and was excited to upgrade my toddler to 2pc she's smaller for her age 20 months got the 2T and the arms are so tight and long I'm waiting for her to tell me they are too tight, was hoping they'd last a few months but definitely size up not for length but for width.
Super cute jammies. Very tight (which they are supposed to be) but glad I bought a size up.
Great PJ's for warm summer months. So soft and comfy!
I have bought many of the one piece and two piece pajamas and am excited for the short sleeve sets for my toddler this summer! They are such high quality fabric and I can’t recommend enough. LOULOU is my favourite brand and I will buy the pajamas for as long as my child fits into them! One of few things that are so worth the price
These are my all time favourite pajamas of any brand I’ve tried. They stay looking new after so many washes and they fit for longer than any other brand too. It’s the only ones I’ve found that have a nice long top and the elastic on the pants is so high quality. Cannot recommend enough! I have ordered the space print in every size because it’s my all time favourite!
I keep buying the two piece pj sets because they keep coming out with cute ones! These are a staple for Christmas, birthday, and just because gifts. They are amazing quality and go through 100 washes with no wear. The ones my baby has outgrown are still in excellent condition we've kept for the next one.
I'm pretty particular about colors and patterns but this bunny and strawberry one is PRECIOUS. Classic storybook vibes. And just soft material. Hope we get more cute prints
