Time to give seamless base layers another try. Seamless construction promises stretch and comfort, but most base layers on the market have a nylon and Lycra® mix that feels comfortable when you put it on but then ends up feeling wet when you're actually riding, and you freeze when you stop. We've worked hard to make this Core Seamless base layer keep you warm and dry, thanks to the addition of polypropylene and polyester yarns, while not compromising the stretch comfort of seamless. We think we've found the sweet spot that also provides a nice level of warmth for cool to cold days.

Good size for everyday use.
Comfy size. You can put your tablet in with ease, has plenty of pocket space for accessories. Fabric is water resistant. The appearance is exactly how it shows as advertised. Good quality which is worth the money. I use it for my Pixel 11 tablet.

Cute, functional, and well-made
I've had this for a while, and would actually like a larger one too for my laptop. This is very well made, with durable fabric, strong zippers and great padding. I can easily fit my Galaxy Tab S9 in its protective case in the padded section inside, my old Kindle Oasis with cover in the zipper sleeve outside, my Galaxy S23 Ultra, also in its case in the slim magnetic pocket outside. It also holds my charging cords, adapter and earbuds in the case. It fits a lot and is not bulky and easily slips into a tote. I'm glad I picked this up, and when it's not moving around, it's useful just for storing cords and accessories.

Looks sturdy and well-made - waiting to use
Not using this yet, but from examining it, this laptop sleeve appears sturdy and durable. The padded protection looks solid for keeping a MacBook safe. The design is versatile - works as a carrying case or travel bag. The handle is convenient, and it's lightweight despite the protective padding. Based on build quality and appearance, this looks like a reliable laptop sleeve. Highly recommend for MacBook owners!

Fits 11” iPad Air with keyboard case
Was looking for something that could hold not just my 11” iPad Air, but also hold it while in its keyboard case with flash sticks and storage for plugs and such. This fits everything perfectly, has good padding, storage pockets inside and out, and feels like a quality build.
