This is my third S'well product and the Traveler design is by far my favorite. The 16oz size fits perfectly in my car's cup holder, unlike the standard bottles. The insulation is top-tier; I tested it with ice water during a hike in 90-degree weather and there was still ice left by the afternoon. My only minor gripe is that the lid can be a bit tricky to thread correctly if you're in a hurry, but once it's on, it's airtight.

They're okay I guess. They definitely stay in place but idk if they totally stopped the snoring. My partner says it's a bit better but not a miracle cure or anything.

Much better than the wooden pole picker I had before. The telescoping feature makes storage so much easier in my shed. It’s definitely worth the money if you have tall trees like I do.

Omgeeee these are gorgeous! I used them for my sisters bridal shower and the terracotta color is perfection. Very flowy and looks way more expensive than it actually was.

I like the idea of stitchless closure but these are a bit bulky under clothing. They work well for open areas like an arm, but on a finger joint it
