The Winter Sleep Onesie Bundle pairs 2.5 TOG and 3.5 TOG onesies at 20% off RRP. Here's what's inside, who it suits, and how to switch between the two.
Quick answer
The Winter Sleep Onesie Bundle contains one Sleep Onesie 2.5 TOG and one Sleep Onesie 3.5 TOG, sold together at 20% off RRP. Use the 2.5 TOG for milder cool nights and move to the 3.5 TOG when the room gets colder.
Why two TOG ratings instead of one
Winter room temperatures rarely stay put. A single onesie can leave you guessing on the nights the temperature drops or the heating kicks in. The bundle gives you two warmth levels from the same range, so you can match the onesie to the room rather than layering extra blankets over a baby who should sleep with a clear cot.
The trade-off is that you only get two options, not a full wardrobe. If your nursery sits at one steady temperature all winter, a single onesie may be enough and the second may go unused.
What the bundle does not tell you
The catalog does not list size options or a temperature-to-TOG guide for this bundle, so check the size chart on each product page before ordering and use the TOG ratings as your warmth guide. It also does not include a sleep bag, swaddle, or thermometer, so this is a sleepwear-only purchase.
Winter Sleep Onesie Bundle FAQs
- What's in the Winter Sleep Onesie Bundle?
- One Sleep Onesie 2.5 TOG and one Sleep Onesie 3.5 TOG. Nothing else is included.
- How much do you save?
- The bundle is 20% off RRP: $111.53 instead of $154.90 for the two onesies bought separately.
- Which TOG should I use first?
- Start with the 2.5 TOG for milder cool nights, then switch to the 3.5 TOG when the room is colder. The catalog does not publish a temperature guide, so judge by how cool the room feels and how your baby sleeps. Keep both onesies accessible so you can switch on a cold snap without searching.
- How do I use the bundle through winter?
- Dress your baby in one onesie at a time, not both together. Move between the 2.5 TOG and 3.5 TOG as the room temperature changes rather than adding blankets.
- Who is this bundle best for?
- Parents in homes where winter room temperatures vary, or who want a spare onesie for wash days. If your nursery stays at one steady temperature, a single onesie may be the simpler buy.
