There's so many options, to include a good compact camera or your cell phone, but this is the best.  Small, intuitive and unmatched image quality.  

Extra Batteries  Screen Protector

A great, compact and very versatile lens.  Prime lenses generally offer the best image quality and you can, in most cases, travel with just this one lens.

Generic EW-52 Lens Hood

This is IT for basic telephoto needs; to include indoors.  You'll rarely need f/2.8 with modern cameras so consider this instead at nearly half the cost and a lot smaller.  Do it right the first time.

This is the best, prices are now ridiculously low and 64GB is all that you'll ever need.  If not, though, it's still better to have two or three 64's than one 128 or larger.  So, maybe get two.

GREAT everyday use size for a camera and a few accessories.  The Mirrorless Mover 20 also has adjustable dividers, handy compartments and magnetic closures.  Very nice quality.

This is a great introduction on how to use your new Canon R8.  Presented by the very best photography instructor of all time; Michael's Channel and Facebook Groups are great resources.

I'm going to declare this essential for anyone.  A great and very handy little flashlight that fits into any pocket.  Takes a single AAA battery and am very partial to these rechargeable ones.

Another semi-essential item for travel; with citronella, geraniol and lemongrass oils to repel bugs.  12-pack size, wear on wrist and/or ankle and store in original bag.  Very convenient.

This is something that you might like to have with you.  Easy carry with a reusable bag and is waterproof, lightweight and durable.  Soft inner layer, side snaps and adj hood.

A GREAT choice for a reasonably powerful power bank that travels well.  You'll need a charger and this USB-C to Lightning or this USB-A to Lightning Cable for some iPhones.

Did the research and this light/durable 3-piece set won.  Select your color and/or 2-piece - the 20-incher works for (domestic) carry-on.  Note that some colors are more/less expensive.

Super comfortable, supportive and durable neck pillow for travel.  Made of hypoallergenic material and soft fiber filling.  Easy to clean/machine washable and takes up almost no space.

This is profoundly ideal for travel to keep your essentials very secure and close to your body.  Please refer to the sizing chart in the Amazon link and select according.  Also comes in blue.

US to Europe outlet adapter.  Note the different ones for different regions/countries.  Has plug and multiple USB-C and USB-A ports.  Very nice for travel and takes up no space.

Highly suggested to spend a few extra dollars for the best wine bottle opener for travel.  Really easy to use, very well designed and made with quality in mind.  Chances are that you'll need this.

A very handy 4.5x4.6x1.8 size that weighs 10.6 oz.  AutoBright Optics automatically dim harsh light and glare.  Ergonomic, textured and waterproof.  The best binoculars for travel.

This is a very versatile umbrella.  Folds down to 11.5" (15 oz.), is extremely sturdy and portable and opens easily.  Great for travel, the car and any other time that you're on-the-go.  A must.

An ultra-durable water bottle that folds into a tiny package.  Select your color and size, but 23 oz. seems perfect for travel.  Odor and taste resistant, dishwasher safe and freezable.

Great for hiking and/or day trips.  Made of water-resistant nylon fabric with adjustable and breathable mesh straps.  Small and light, but with a large 22L capacity.  Select from several colors.

My top choice for ticks and mosquitos.  Natural plant-based lemon and eucalyptus oil.  Has a strong, but not bad odor.  Only one recommended by the CDC.  Essential for hiking.

The Sawyer 20% Picaridin Insect Repellent is considered to be the most effective choice and is considered safe.  Lasts for 8-12 hours, has a mild citrus odor and comes in a pack of 2.

Breathable, supportive (15-20mmHg) and very comfortable.  Promotes circulation and minimizes fatigue.  Moisture wicking 85% nylon/15% spandex.  Pack of 3.  Select color.

Very strong and light aluminum collapsible walking stick with comfortable foam handle and nicely designed tip.  Adj. from 43.3"-49.2".  

You may need 2.  Select color.

pH optimized for amazing odor control.  Hypoallergenic, very safe and even works on the feet.  My favorite is Soft Powder followed by Unscented.  2-pack and comes in other scents.
