Size: Sidekick 3L
The YETI SideKick waterproof gear case is exactly what you’d expect from YETI—durable, well-made, and built to protect your essentials. It’s truly waterproof and keeps items like your phone, keys, wallet, and cards completely dry, even around water. The case feels rugged and secure, with a strong magnetic closure that’s easy to open and close but seals tightly. It’s a great size for everyday essentials without being bulky, and it attaches easily to bags, coolers, or belts for convenience. Perfect for boating, beach days, kayaking, or any outdoor adventure where you want peace of mind. Pricey, but absolutely worth it for the quality and reliability.

Love the sidekick! Was a great addition to my Yeti Camino bag! Took it to the river recently and kept my phone e and others phones inside so they wouldn't get hot or wet and it works amazing! It's the perfect thing to protect items, very durable and easy to clean. Holds a lot and can easily find what's in there. It seems like a thick material but it's not heavy at all. Absolutely love it as a side bag as well!

Fits perfectly onto my Yeti cooler, very secure and the size is substantial. Waterproof for sure. Closes easily and stays closed tight.

Beautiful color, I use it for silverware, napkins and spices as it’s attached to my m20 cooler backpack and it’s been working great for me

This is the best waterproof bag on the market! Very durable, and the 3L is the perfect size for a day trip for 1. It fits my keys, chapstick, phone, meta glasses case, a full water bottle, and a snack. Sometimes, I can even squeeze a lightweight tank and shorts in there too. The Velcro closure and magnetic closure makes your items super secure and can guarantee your inside of the bag will not get wet. It’s got a side elastic pocket to fit a wallet and is super easy to wipe down with a wet rag. This is not a thermal bag, but rather a highly durable, thick waterproof bag.

I’ve owned a lot of outdoor gear over the years, and this is exactly what I’ve come to expect from YETI—premium quality with thoughtful design. I purchased the 3L SideKick Waterproof Gear Case to keep my everyday essentials protected while traveling, boating, and spending time outdoors, and it has exceeded my expectations. The waterproof construction feels incredibly durable, and the material is thick without being bulky. The magnetic closure is one of my favorite features—it seals securely and it’s super easy to open with one hand. The 3L size is perfect. It easily fits my wallet, keys, phone, sunglasses, charger, and other small essentials without feeling oversized. The bright red color also looks fantastic in person and makes it easy to spot, whether it’s sitting on a boat, in the truck, or on a campsite table. What really stands out is the overall build quality. Every seam, edge, and detail feels premium. It’s one of those products you immediately recognize as being built to last for years. As expected from YETI, nothing about it feels cheap. If you’re already invested in the YETI ecosystem or simply want a rugged waterproof gear pouch that you never have to worry about, I highly recommend this one. It’s expensive compared to some alternatives, but after using it, I completely understand why. It’s one of those purchases where you pay more once and likely never need to replace it.
