Super comfortable and roomy. The helmet hood is what really makes it — already thinking about getting another team!

FAQ

check_box

Will It Fit Me?

Go by your height first — but if you're broad through the chest or middle, size up one from there. It's fleece, it's meant to be roomy, and nobody wants it tight.

S fits 5'0"–5'3"

M fits 5'3"–5'7"

L fits 5'7"–5'10"

XL fits 5'10"–6'1"

2XL fits 6'1"–6'4", cut wider through the body

3XL fits 6'4"+, cut wider again

Small and want it fitted? Order your height. Bigger guy, or you just want to disappear into it on the couch? Go a size up — it's built for that.

It's cut roomy on purpose — wear it straight over your pyjamas, loungewear, or jeans. The ankles finish in a ribbed cuff, so it sits above your feet and you wear your own socks or slippers. Between two sizes? Always go up.

Can I Use My Hands In It?

Yes. The sleeves have open cuffs so your hands slide straight out whenever you need them — grab your phone, hold a drink, reach for the nachos. You're not stuck.

Is It Actually Warm Or Just Looks Warm?

It's actually warm. Thick soft fleece all the way through, about 2 lbs of it. Most people end up too warm and have to unzip. If you run cold, you'll love it. If you run hot, maybe keep a window open.

Reviews

  • Perfect for game day

    Honestly didn’t expect much but this is ridiculously comfortable. The helmet hood is what sold me. Wore it all Sunday watching the games and basically didn’t take it off.

  • My boyfriend loves it 😂

    Bought this for my boyfriend and he absolutely loves it. The hood is so much better than I expected and the whole thing is really soft.

  • Best game day purchase

    Best game day purchase I’ve made. It’s oversized without feeling completely ridiculous, and the material is actually really warm.

  • Such a cool gift

    I got this as a gift for my brother and he immediately put it on. The helmet hood is such a cool detail. Definitely recommend.

  • Really comfy fit

    Really comfortable and looks exactly like the pictures. I’m 6ft and got XL which gives me plenty of room. Could probably have gone L but I like the oversized fit.

  • Official Sunday outfit

    My husband has basically claimed this as his official Sunday outfit 😂 Super soft, roomy and the hood is hilarious in the best way.

  • The hood is awesome

    The helmet hood is SO cool. I thought it would just be printed on but it actually has some structure to it. Definitely the best part of the onesie.

  • Everyone loved them

    Bought one for me and one for my dad. We wore them during the game and got so many comments on them. They’re really cosy too.

  • Great oversized fit

    Fits really nicely. I’m 5’10 and went XL because I wanted it baggy and it’s perfect. Sleeves and legs are nice and long.

  • Way warmer than expected

    Really fun onesie and surprisingly warm. The team details make it look much better than a generic football onesie.

  • 10/10 😂

    The hood makes this thing. I wore it to a game night with friends and everyone wanted to know where I got it.

  • Better quality than expected

    Quality is better than I expected for the price. Soft inside, plenty of room and the zipper feels solid. Already thinking about getting another team.

  • Dad absolutely loved it

    Got this for my dad who is impossible to buy for. He actually loved it and wore it the entire evening. Huge win.

  • Sizing was spot on

    Super cosy and the sizing guide was accurate. I’m usually between sizes so I sized up and it gives that perfect oversized fit.

    Alex P.

  • I want every team now 😂

    Really cute and comfortable. The helmet hood is definitely the standout feature. My only problem is that I now want one in every team 😂

  • Made for lazy Sundays

    Perfect for lazy Sundays. It’s warm without being ridiculously heavy and the hood makes watching football about 10x more fun.
