Overall the quality is great, but I did find some of the thread came loose around the pocket and the lining at the bottom. It's still intact and useable so it hasn't been a real issue, but I'd be disappointed with this had I paid more for the blanket hoodie. But, at £20, it's something I can easily overlook.
The biggest drawback of the Sienna is the lack of design options available. It is available in seven colours, but that's not a scratch on the surface of what you can get from the Sienna's biggest rival, the Oodie (we've tested this also - don't miss our Oodie review to compare). With Oodie you do have a lot more design choice – their blanket hoodies feature everything from avocados to chicken nuggets, otters to corgis – but they are significantly more expensive, with prices starting at £54.
Does it wash well?
I confess I was a little apprehensive about washing the Sienna, fearing it would lose its softness in the wash. I also love wearing it so much that I wasn't keen to part with it, even for a just a day. However, the instructions were clear and I was pleasantly surprised that it came out still fluffy and soft.
The Sienna is machine washable at 30°C, and I chucked it in the machine with a regular load of washing. It washed well and dried quickly on an airer, even in a cold house, so I didn't have to wait too long to get back into it (luckily my dressing gown was on standby during drying time!)
Our verdict: Sienna Hoodie Blanket review
I love the Sienna Hoodie Blanket. It's soft, warm and cosy, and I've used it every single day since it arrived. With over 20,000 five-star reviews on Amazon, it's a huge hit amongst wearers and it definitely helps if you're trying to keep the thermostat down more this winter too.
If your budget does stretch to it, the Oodie is better quality and you can pick up a vast range of fun patterns from there too. However, not everyone can splash out £60+ on a blanket hoodie and, at just £13, the Sienna offers fantastic value. It'd make a great gift too – I'm certainly giving it as a few Christmas presents this year!
