Our tracksuit collection is designed to grow with your family from the very beginning — available in sizes from 0–6 months all the way through to age 6. That means whether you're dressing a brand new newborn or an unstoppable five-year-old who hasn't sat still since 2022, there's a Cozy Crew Club tracksuit built exactly for them.

For babies in the 0–6 months to 12 months range, our tracksuits are cut with extra softness and freedom of movement in mind — no restrictive waistbands, no scratchy seams, nothing that gets in the way of rolling, stretching, and all the important work of being a newborn.

From 12 months through to age 6, our tracksuits are designed to keep up with the relentless energy of toddlers and young children — durable enough for the playground, comfortable enough for the sofa, and soft enough for sensitive skin at every stage. And because every set is 100% GOTS certified organic cotton, the same gentle, chemical-free fabric that's right for a newborn is just as right for a six-year-old.

Most children's tracksuits on the market are made from polyester or a polyester-cotton blend chosen because it's cheap to produce, quick to dry, and easy to manufacture at scale. But for everyday clothing that sits against your child's skin for hours at a time, the fabric choice matters far more than most parents realise.

Infants and young children have thinner skin and spend long hours in direct contact with clothing even minor chemical releases from synthetic fabrics could matter, and everyday contact with textiles can lead to low but measurable chemical exposures.

Polyester is derived from plastic, doesn't breathe, traps heat and moisture against the skin, and is increasingly associated with microplastic release during washing — particles that end up in waterways and, ultimately, in the food chain. For active children who run hot and sweat during play, a non-breathable synthetic fabric is uncomfortable, clammy, and counterproductive.

Our 100% GOTS certified organic cotton is the opposite in every way. Naturally breathable, it allows air to circulate freely so children stay comfortable and cool during active play. Naturally soft, it feels gentle against sensitive skin without the pilling, scratching, or static that synthetic fabrics create over time. And grown without synthetic pesticides or chemical fertilisers, it's free from the harmful residues that conventional cotton processing often leaves behind — including phthalates linked to hormone disruption and formaldehyde finishes used for wrinkle-free properties.

For a tracksuit your child wears every day, 100% cotton isn't just a nicer choice — it's the right one.

Appliqué is a decorative technique where a shaped piece of fabric or embroidered design is carefully applied to the surface of a garment to create a pattern, motif, or image — giving the clothing personality and charm that goes far beyond a simple printed design.

At Cozy Crew Club, our appliqué designs are crafted with the same care and attention as the rest of the garment. Every appliqué is applied flat to the fabric surface and finished to sit smoothly against the clothing without raised edges, loose threads, or rough backing that could catch or rub against your child's skin. The result is a beautiful, distinctive detail that looks stunning and feels completely comfortable to wear.

Safety is always our first consideration with appliqué — particularly for babies and young children who may touch or mouth their clothing. All our appliqué work uses non-toxic materials that meet the same safety standards as the rest of our GOTS certified organic cotton range. No sharp edges, no small detachable parts, no chemical finishes. Just beautifully crafted detail that makes every Cozy Crew Club tracksuit instantly recognisable and genuinely special.

Yes — and this is one of the things that makes Cozy Crew Club tracksuits genuinely stand apart from everything else available in organic children's clothing. Every tracksuit in our collection can be personalised with your child's name, transforming an already brilliant everyday essential into something completely unique to them.

A personalised tracksuit is one of those gifts that hits every mark simultaneously — practical enough to be worn every single day, personal enough to feel genuinely special, and beautiful enough to be kept long after it's been outgrown. It's the kind of present that gets commented on constantly, gets worn immediately, and becomes one of those treasured early-childhood pieces that parents hold onto for years.

Our personalised baby tracksuits and personalised kids' tracksuit sets are among our most popular gift choices for baby showers, first birthdays, Christmas presents, christening gifts, and new sibling gifts — because a name on a beautifully made organic cotton tracksuit says more than any generic present ever could. Simply choose your size, select your style, add the name, and we'll take care of everything else.

Absolutely — and our 100% cotton makes our tracksuits one of the most skin-friendly choices available for babies and children with eczema, allergies, or reactive skin.

Buying GOTS certified cotton clothing greatly reduces the likelihood of exposing your child to endocrine disruptors and carcinogens that can be present in conventionally produced garments. Our organic cotton is grown without synthetic pesticides, processed without toxic dyes or chemical finishing agents, and certified independently at every stage of production — so you know exactly what is and isn't in the fabric sitting against your child's skin all day.

Our tracksuits are designed without scratchy internal tags, rough seams, or unnecessary fastenings. The naturally breathable organic cotton allows air to circulate freely, reducing the overheating and sweat retention that are among the most common triggers for eczema flare-ups during active play. And because our appliqué detailing is applied flat and smooth to the fabric surface, there are no raised edges or rough backing materials that could catch on sensitive skin.

If your child has particularly reactive skin, we always recommend washing new tracksuits before the first wear using a gentle, fragrance-free detergent — and avoiding fabric softeners which coat the natural fibres and reduce their breathability over time.

Yes — and we mean that in the fullest sense of the word. Our tracksuits aren't just available in both pink and blue and called unisex. They're genuinely designed from the ground up in timeless colours, classic silhouettes, and playful appliqué motifs that work beautifully for any child, regardless of gender.

Gender-neutral sizing and versatile inclusive designs make it easier to pass clothes between siblings and reduce overall consumption — which is why our unisex tracksuits have become one of our most gifted product ranges. When you're buying for a new baby whose gender you don't know yet, buying for multiple children, or simply choosing not to let gender define what your child wears, our tracksuits are the answer every time.

The unisex design also makes our tracksuits exceptional hand-me-down pieces — worn beautifully by one child and passed naturally to the next without any of the limitations that gender-specific clothing creates. In a world where sustainable choices matter, a truly unisex, 100% organic cotton tracksuit that outlasts multiple children is one of the most genuinely planet-friendly things you can buy for your family's wardrobe. Add personalisation with your child's name and even a completely unisex design becomes entirely unique to them.

Our tracksuits are built to be washed constantly — because children are magnificent chaos machines and laundry is just part of the deal. Here's how to keep them looking and feeling their best wash after wash:

Machine wash at 30°C or below on a gentle cycle using a fragrance-free, baby-safe detergent. Avoid biological detergents which can break down natural cotton fibres over time, and skip fabric softeners entirely — they coat the organic cotton and reduce the natural breathability that makes our tracksuits so comfortable for active children. Tumble dry on low heat or air dry flat for the best results and longest life.

Turn tracksuits inside out before washing to protect the appliqué detailing and any personalisation — this keeps embroidery and decorative elements looking crisp and vibrant through hundreds of washes. Wash darks with darks and lights with lights to maintain the depth and freshness of the colours.

One thing parents consistently tell us: our 100% organic cotton genuinely gets softer with every single wash rather than stiffer or thinner — so the tracksuit that feels wonderfully soft on day one keeps improving the more it's worn and washed. Built to last through the whole childhood, not just the first term.

Getting the size right for a growing child is one of those things that looks simple and turns out to be surprisingly nuanced — so here's the practical guide to getting it right first time with Cozy Crew Club:

Our tracksuits are sized by both age and height, and we always recommend checking the height guide rather than relying purely on age, since children vary enormously in size even within the same age bracket. A child who is tall for their age will need the next size up even if the age label suggests otherwise — and our size guide accounts for this directly.

When between sizes, always size up rather than down. Children grow at a remarkable pace, and a tracksuit with a little growing room will serve you far longer than one that fits perfectly today and is too small in six weeks. Our cotton jogger bottoms feature a comfortable elasticated waistband that adjusts easily as children grow, and the natural gentle stretch of our organic cotton fabric means the top moves with your child's body rather than restricting them.

For gifting, if you're unsure of the size, our general advice is to go one size above what you think — children grow into clothes far faster than you'd expect, and a slightly bigger tracksuit worn for longer is always better value than a perfectly sized one that lasts a single season.

One of the things parents love most about our organic cotton tracksuits is their year-round versatility — and that flexibility comes directly from the natural properties of 100% organic cotton.

In spring and autumn, a Cozy Crew Club tracksuit is the perfect standalone outfit — warm enough for cooler days, light enough to not overheat during active play, and comfortable enough to be worn from morning to bedtime without a single complaint from even the most strong-willed toddler.

In summer, our tracksuit tops can be paired with shorts for a lighter combination, or worn as a standalone layer on cooler summer evenings. The natural breathability of organic cotton allows air to circulate freely against the skin — keeping children comfortable during active outdoor play without the sweaty, clammy discomfort that synthetic fabrics create in the heat.

In winter, the tracksuit becomes a brilliant mid-layer — worn over a long-sleeve organic cotton bodysuit or under a coat for extra warmth on colder days. The natural insulating properties of organic cotton hold gentle warmth close to the body without the bulk or restriction of heavier synthetic fleeces.

Four seasons. One tracksuit. That's the Cozy Crew Club way.

Genuinely one of the best gifts you can give — and here's exactly why parents and gift-givers consistently tell us our personalised tracksuits are among the most loved presents they've ever given or received.

Most baby shower and birthday gifts fall into one of two camps: the beautiful but impractical, or the practical but forgettable. A personalised organic cotton tracksuit sits in an entirely different category — it's worn immediately, used constantly, and remembered long after every other gift has been forgotten. The personalisation makes it feel genuinely special. The organic cotton makes it feel genuinely luxurious. And the quality makes it last long enough to become one of those treasured childhood pieces that parents hold onto forever.

For baby showers, our 0–6 month personalised baby tracksuits are a consistently popular choice — practical from day one and special enough to stand out among a sea of generic gifts. For birthdays, our toddler and kids' personalised tracksuit sets make a brilliant present for any age from 1 through to 6 — something a child will immediately want to wear and a parent will genuinely appreciate.

Add our personalised organic muslin, bodysuit, or sleeping bag to create a complete Cozy Crew Club gift set — the most thoughtful, most useful, and most personal new baby or birthday gift imaginable. 🎯🌿
