Why compromise when you don't have to? The Mayhem 45 is ultralight, ultra-durable, and ultra-comfortable. Built with Spectra® Fiber, the pack offers a top tier strength-to-weight ratio. Used by military and law enforcement, Spectra® Fiber is an ultra-high-molecular-weight polyethylene known for its lightweight strength and abrasion resistance properties. In the Mayhem 45, this means more efficient pack carry, more mileage, and a lifetime of adventures. Less pack weight also means more room for the essentials - like melted chocolate bars and squished PB&Js.

At 45 litres, the Mayhem 45 is designed for one-to-three-night backpacking trips, backcountry huts trips, gear heavy days at the crag, and adventure travel. The hybrid top and panel opening offers easy access to the front of the pack, a must-have for tight environments and organized packing. Toss the Mayhem on your back and the hex-ridged EVA back panel padding allows for omni-directional airflow while the sock-style shoulder strap construction prevents the straps from digging into your body. The Interfaced Waistbelt system is designed and patterned to flow into the back panel allowing for a lightweight but intimate suspension fit and high levels of stability and comfort.

A TERRIFIC FIND FOR US IN ECUADOR
Size: 5.5 Ounce (Pack of 1)
Here in Ecuador, this product isn't even available to us. I have the most precious 20 month old girl living with us and of course I wanted to get a quality product at less cost. This fits the bill. With an SPF 100 rating from a decades old and trusted manufacturer and a price that is less than one third of what I would have to pay for any sort of water resistant equivalent, this was a no brainer. If you buy this product, please read the instructions and follow them. It is a spray product that great care should be used to avoid spraying directly on the face--------- either your own or the child's. Spray it on your hand and apply it to any face that needs it. It's convenient for neck, shoulders, backs and legs due to its spray delivery. Our little 20 month old must be part fish because she loves the thermal pools we take her to and this product seems quite durable

SPF 100 FTW
Size: 5.5 Ounce (Pack of 1)
I find it very important to have strong sunscreen. Thankfully I found this with 100 SPF. So glad plus I’m happy that I found it in spray because it’s so much easier to apply the kids and then I just have them rub it in. It also makes reapplying so much easier because just start spraying and have them turn around and around that you’re good to go.

Not eczema skin friendly
Size: 5.5 Ounce (Pack of 1), Size: 5.5 Ounce (Pack of 1)
Since I didn’t remember which sunblock spray I had previously purchased (that was super awesome), I got this one with a few other ‘kid’ sunblock spray and stick. I had grabbed this one for a splash pad birthday party this weekend only to find out it’s messy and not eczema skin friendly. Either we got a defective bottle or it’s just the way it sprays: runny goops of sunscreen that takes awhile to dry properly (see photo). And when it dries it really does stick onto your skin as advertised (aka not breathable, pore clogging, will irritate sensitive/eczema prone skin). My youngest has eczema prone skin (that’s been flare up free for 3 years) had a severe break out on her arms after using this. And even for the sake of photo demonstration for this post my own sensitive skin got red/irritated. So does it stick-yup. Is it messy? Definitely. Easy to apply? No (your kiddos have to stay put until it dries). Did it provide sun protection? Maybe…? Sensitive skin friendly? No. Eczema skin approved? Definitely not. Recommended? Nope. We threw it away and requested a refund.

I love it
It does its work. I know many people don't like mineral sunscreens because of the white look on the skin( which it goes away once you rub it right), but I'm telling you, it's the only ingredient that it actually protects you from the UV rays and getting sunburn. The little one it's amazing and my kids love it because it's easy to put on.

Great children's sunscreen for sensitive skin
I really like this children's sunscreen. The facial stick that comes with it is quite small but it's still very convenient and works well. You do need to rub the facial stick in once it's applied to your child's face. The spray sunscreen also needs to be rubbed in as well because it comes out a little thick but is easy to rub in. There is not really a scent to it so my kids don't mind it being applied. My kids have sensitive skin too and we have had no problems as well. Would highly recommend!
