Summertime may not quite be here yet—at least for those of us in the northern reaches of North America—but there’s already a case in this week’s roundup that can’t wait to accompany you to the beach or the pool. We also have some vintage nostalgia, something to help you exercise without worrying about what’s happening to your electronics, and a case that will have you taking better pictures in a snap.

The Wello (iPhone 5 and 5s; $220) is a case that incorporates a special reader capable of taking your pulse, blood pressure, tempoerature, and even blood-oxygenation level.
The case, available for preorder, will also include an attachment that can help you get a handle on your lung function.

The TruRunner (all iPhone models; $20) is a pouch that goes around your waist and offers plenty of room for your iPhone, wallet, keys, and everything else you need while you’re out exercising.
Available in black, it features a fully adjustable belt that fits snugly without bouncing around, as well as a built-in reflector for extra safety at night.

Ready for a bit of nostalgia? The Vintage Childrens Books (iPhone 4, 4s, 5, and 5s; $37) is made from rigid, polycarbonate plastic and is handmade to order.
The case features a shot of the spines of several classic Dr. Seuss books, such as Green Eggs and Ham and Yertle the Turtle.

The Laser Engraved (iPhone 5 and 5s; $13) is a slim, polycarbonate case with a metallic finish that, as the name suggests, has been laser engraved with a word-art motif.
The case comes in grey, pink, blue, orange, red, or black.

If you live in the northern hemisphere, it’s likely that pools and beaches aren’t quite in your sights yet, but the Surf Sound Play (iPhone 4, 4s, 5, and 5s; $72) is ready to help you take your handset with you when the sun finally does start shining.
Waterproof and dustproof, the case supports most recent smartphones, and it includes a speaker powered by three AAA batteries.

If you take photography seriously, the iProLens line (iPhone 4, 4s, 5, and 5s; $49 to $229) is a case that enhances your handset with an interchangeable system of lenses.
Each lens in the system is precision made from high-quality optics with a durable housing, and offer focal lengths that range from fisheye to tele.

The Tonewood (iPhone 4, 5s, 5, and 5s; $80 to $90) is a line of cases made from premium woods, with two-piece construction for easy installation, and wooden button inserts for maximum protection.
Each case is available in mahogany, maple, or rosewood.

The TopoCharger (iPhone 4, 4s, 5, and 5s; $149) comes with a built-in rechargeable battery that doubles your handset’s life while protecting it from bumps and scratches.
If that weren’t enough, the case also incorporates the company’s Map Card technology, which allows you to view topographic maps—great for orienteering and hiking—even when you’re nowhere near a cell tower.

The Defense 720 (iPhone 5 and 5s; $35) provides protection from all angles, including a sturdy front screen protector, drop-resistant back plate, and a rubber bumper that enhances your grip.
The case is available in black, purple, or aqua.
