Because blankets belong at home, you shouldn't have to look like you're in a post apocalyptic movie on the sidelines.
Most puffers make you look like the Michelin Man — bulky, overstuffed, and more at home on a mountain expedition than at your kid’s game. And too many hide cheap synthetic fill inside that leaves you cold anyway. The Sideline Puffer is different. It’s filled with pure, responsibly sourced goose down — no synthetics here — so you get serious warmth without the bulk or marshmallow vibe.
If you’ve spent a Saturday freezing through back-to-back games, you know what true cold feels like. The Sideline Puffer was made for exactly that life — whether it’s 7 a.m. on frosty fields or night games under the lights. The Infinity Pocket gives your hands a shared, hoodie-style refuge, while the durable rip-stop nylon shell keeps wind and drizzle at bay.
Inside, fully box-baffled quilting ensures even insulation, while the silky, fully lined interior feels as good as it performs. With ethically sourced 90/10 goose down, a 650 fill power rating, and a PFAS/PFC-free finish, this jacket blends luxury comfort with sideline toughness.
It’s tournament-tested, warm enough for the coldest sidelines, but streamlined enough for everyday wear — so you don’t have to look like you’re hiking Everest just to cheer for your kid.
Key Features:
Premium Goose Down Insulation: 90/10 ethically sourced goose down, 650 fill power, exceptional warmth. No synthetics — only the real thing.
Silky Woven Rip-Stop Nylon Shell: 100% polyester rip-stop with PFAS/PFC-free finish for durability and style.
Fully Lined Interior: Enhanced comfort and protection against the cold.
Ultimate Insulation: Fully baffled quilting for uniform warmth.
Infinity Pocket: Hoodie-style hand warmth in a shared, soft-lined space.
Care & Guarantees:
30-Day Tryout Guarantee — Wear it on the coldest game day. If it doesn’t make a difference, return it free.
Lifetime Zipper Warranty — Because the zipper should never be the weak link.
Easy Care — Machine washable and dryer safe, because no parent has time for dry-clean-only gear.

I have owned MANY winter jackets from all the top name brands including ski jackets that I wear when skiing out west. This jacket is by far the warmest jacket that I own. Every time (in the winter) that I step outside, it is the jacket that I grab. I seriously love this jacket and am glad to represent the brand in the northeast!

Try it, you will love it…. .
All I can say is that I wish, I found this jacket sooner. I think the quality is the same if not better than other top end brands and I bought it for a much more reasonable price. I now wear this jacker over other more expensive jackets that I have in my closet because it is just better…plain and simple. I also love the infinity pocket which I could not find in another jackets.
