Description

The Sleep Store Jersey Merino Cosy Arms are a simple, clever solution for preventing accidental scratches and keeping little hands and fingers warm during the cooler months. Made from 100% NZ merino wool in a soft single jersey knit, these cosy arms provide natural warmth while remaining breathable and gentle against delicate skin. Merino is beautifully temperature regulating, helping keep hands warm without overheating, and it feels soft and comfortable even for little ones with sensitive skin.

Designed in a mitten sleeve style, it slips gently over your child’s arms and shoulders, much like a small cardigan or Bolero. It has 2 press studs at the front to secure closed and has fold over mittens attached at the ends. Unlike traditional mittens, they stay securely in place, so you don’t have to constantly replace or reattach them. Choose to layer under a sleeping bag to keep small hands warm and prevent accidental scratches.

The single jersey knit gives a smooth, flexible finish with just the right amount of stretch, allowing for easy movement while still providing a snug fit.
Available in sizes from 3 months through to 5 years, they're designed to grow with your child through those busy early years.

Care for your merino

As with many wool garments, you may experience a bit of pilling on this garment. Please note this is often due to a soft fibre such as merino rubbing against other fabrics, such as flannelette sheets. We consider pilling a normal part of wear and tear on a soft merino garment. We could have treated the fabric much more to reduce pilling but then it would lose its lovely, snuggly softness.

Please take care with moths

Protect your merino from small holes created by insects such as moths and silverfish. Ensure your garments are clean before storing. Lavender and cedarwood are noxious to these pests so storing your garments with these scents or a moth trap will help protect your knitwear further.

Love your merino and it will love you back!

What are the major differences between The Sleep Store merino wool garments?

Basics Merino Our entry level 100% merino wool. At 190gsm it is the lightest weight of our 100% merino wool offerings but not as fine (or silky smooth to touch) as our Deluxe Rib or Jersey Merino. It is a great affordable and durable option. All Seasons Merino Tencel This is an everyday collection made from a 70% merino wool / 30% Tencel. The jersey blend fabric has a silky, cool feel, and is the lightest merino wool blend option at 165gsm. The Tencel blend makes it great for wearing all year round and ideal for sensitive skin. Jersey Merino Made from 100% New Zealand merino wool, it is super smooth and soft. It feels like high-quality t-shirt fabric and has a comfortable stretch — not as much as the Deluxe Merino rib. Great for layering all year round at 200gsm. Deluxe Merino Rib Made from 100% New Zealand merino wool, this range uses a rib knit merino wool, meaning its structure consists of rows of stitching. This gives this merino wool a beautiful stretch with cross-grain elasticity. It is so soft and great all year round at 220gsm. Fleece Merino Tencel Super warm at 270gsm, ideal for cold nights and wintry days. Made from a blend of 68% merino wool, 29% Tencel and 3% elastane, this range is super soft and fluffy on the inside with a sweatshirt feel on the outside. Premium mid-weight Merino A beautiful soft and thick 100% merino wool interlock which allows for comfortable stretch whilst retaining shape. A lovely warm option, at 250gsm it is our warmest 100% merino option. This is our only 100% merino that is available in prints. Merino Knitwear Crafted from 100% merino wool. Comes in 3 different stitch patterns depending on the garment — seed stitch, classic stitch and brioche stitch.
