My outdoor experience began in high school with a co-ed scout group which made a 10-day canoe voyage through the Quebec wilds. I've been backpacking since college in Pennsylvania. I have hiked 1/4 of the Appalachian Trail and 2/3 of the Pacific Crest Trail. My typical trip is in the Sierra Nevada from a few days to a few weeks long. My base weight is lightweight at 15 lb (6.8 kg) while still using a tent, stove and quilt. Longer mileage summer trips are now stoveless.

TK ClosureTwist CapThe Klean Kanteen TKWide Water Bottle is a stainless steel, vacuum insulated wide-mouth bottle. It is BPA-free and uses 90% post-consumer recycled stainless steel. The bottle is dishwasher safe with a reinforced base cap for impact resistance. The color (yellow in my case) is a chip-resistant powder coat finish. The TKWide lids have screw threads, but the bottle has a unique thread pattern formed with raised bumps into a thread pattern rather than the typical screw threads. The wide mouth allows for easier cleaning and the lip is rounded for comfortable drinking (if not using one of the nifty lids). Klean Kanteen claims that iced contents will stay that way up to 66 hours.

The TKWide Twist Cap twists closed to create a leakproof seal and twists open to reveal a silicone straw mouthpiece. Under the cap is a stainless steel straw which extends into the bottle and a silicone straw which can be cut to length to reach to the bottom of the water bottle. The Twist Cap allows use of a straw while providing a way to keep the tip of the straw clean and to seal it when not in use. Very hot liquids are not recommended since the steel straw can get too hot. Carbonated beverages are also not recommended. The Twist Cap has a steel swivel loop for easy carrying which is designed to stay out of the way when drinking from the straw.

Chug CapLoop CapThe TKWide Loop Cap provides a leakproof solid closure to the bottle and has a steel swivel loop for easy carrying. It is a vacuum insulated lid with a stainless steel bottom to provide an all-stainless interior.

The TKWide Chug Cap is made for drinking water or other hydration beverage quickly with a high-flow spout. The mouthpiece is made of silicone and the mouthpiece lid is unique in that it can snap down quickly for easy access during a game or other frequent use but can be screwed down securely for travel or carrying. The top of the mouthpiece lid can also be snapped to the steel swivel carry loop to keep the lid out of the way when drinking. Genius.

I like Klean Kanteen's commitment to the environment too. Reusable water bottles certainly help people to eliminate those pesky one-use plastic water bottles with the added benefit of not containing health-harming BPA or other chemicals. Plus Klean Kanteen uses recycled stainless steel (90%). My favorite though was the packing materials in my shipment which consisted of NO plastic and entirely paper products (tissue and a neat expanded version of brown paper) which I'll be saving to reuse. Very impressive.


My initial impression is how well-designed this product is. From the powder-coated bottle exterior to all of the little thoughtful features on the caps to make them not only functional but also, shall I say, not a pain in the neck to use. The Twist Cap is a marvel by providing a way to drink through a straw and yet keep the straw tip clean and leakproof when not in use. Of course, I'll test all of this out, but I'm impressed with the thought that has gone into something as 'simple' as a water bottle.

The wide mouth should make it easy to fill not only with beverages but also with soups for winter snowshoe picnics. The wide mouth should also make it easy to clean when I get home.

After reading the information about each aspect of the bottle and caps, I washed everything to prepare it all for use. Then I filled the bottle to the rim of the main interior compartment and measured the amount. Then I tried drinking from the bottle using each cap type and tried to shake and tip the bottle to see if anything leaked. The lip of the bottle itself was comfortable to drink from as were the Chug and Twist Caps.

Lastly, I checked the fit of the bottle in my day pack and was happy to see that it should be a good fit.
