The soft launch of summer (Memorial Day weekend) is just around the corner, meaning that pretty much everyone is gearing up to spend longer and hotter days in the sun.

The need for cute and functional coolers, a good backpack for hiking, and of course, a reusable water bottle that actually keeps your drink cold is never greater than it is during this time of year, which is why we're stoked that Hydro Flask's sitewide summer sale has all of the above, and some more, available for 25% off.

And for those looking to get the most out of their Prime subscription, you'll also find those deals (and some at even steeper discounts) available on Amazon.

Obviously, sitewide availability means there's plenty of summer essentials to shop from, which is why we've pulled a few of our favorite picks. Check them out below:

Why we like it

You can't go wrong with any Hydro Flask bottle (and they are our absolute favorites for keeping drinks ice cold), but the 24-oz Standard Mouth with the Flex Straw cap checks a lot of boxes. It holds a decent amount of water so you won't have to refill every hour, can still fit in a cup holder, and can easily be sipped thanks to the straw cap (which is more leakproof than past versions from Hydro Flask). If you grab it in the snapper colorway, you can save 40%, but every other color is still 25% off, putting the bottle at $33.69.

BEST BAG: 20 L Insulated Tote — $48.71 (save $16.24)

Why we like it

The underrated hero of the beach day is the insulated tote, and this one from Hydro Flask offers a lot. It's big enough to hold plenty of food, plus a bottle of wine standing up, according to one reviewer on Hydro Flask's website. It has a freestanding base, waterproof fabric, and an exterior pocket for holding anything you need easily in reach. In the off-season, it also makes a great reusable bag at the grocery store.

BEST BOTTLE UPGRADE: Flex Straw cap (standard mouth) — $10.98 (save $3.97)

Why we like it

If you're already a proud Hydro Flask owner, there's still plenty to shop at this sale. Without spending much at all, you grab this Flex Straw cap, which is a far cry more convenient than the standard twist-off lid. If you already own the old Hydro Flask straw lid, I will say with the authority of someone who's diligently used both that the Flex Straw cap leaks less.
