For the alpinist looking for a lightweight, low bulk bag suitable for cold temperatures, the Neutrino 400 offers exceptional packability and warmth for its weight. Designed with a narrow mummy fit, for reduced bulk and pack size, and constructed with lightweight, high performance materials. It’s perfect for three season mountain missions. The Neutrino 400 is filled with 400g of 800FP, goose down, stabilised in chevron shaped baffles, cleverly designed to reduce the amount of fabric needed compared to traditional horizontal baffles. The trapezoid boxwall baffle construction allows the down to fully loft, eliminates cold spots, and maximises warmth. Additional baffles along the length of the zip and around the neck decrease heat loss, and with an adjustable drawcord around the hood you can cinch the bag around your face. Now built with a recycled nylon lining and recycled Pertex® Quantum outer, it’s wind resistant and a little lighter on the planet too. The down is also finished with a Nikwax, fluorocarbon-free hydrophobic treatment for coping with condensation.- Weight saving chevron baffle design, reduces down migration and optimises core warmth.

Perfect for people who take carry on bags flying to beach vacation!
Style: Spray (2 Oz)
THE only spray on sunscreen, that is NOT a 200 SPF, thats less than 3.5 ounces so TSA doesnt confiscate it from bag en route to Cancun. I keep a few in the drawer and take the partially used one from last trip to finish off plus a new sealed one as backup. Smells great and sprays a fine lovely mist so you dont fry. LOVE this product. A GREAT purchase. We dont check bags and its hard to find ANY product in under 3.5 ounce packaging. Sure you can pour sunscreen into bottles that mfg says do not leak, but youll learn the hard way that they DO leak all over the inside of your suitcase. Skip that learning experience and buy COOLA.

Best Sunscreen and Reef Safe
Style: Spray (6 Oz)
I've been using this sunscreen for a couple of years now and this is the one! The lotion and the spray are both great, smell good and are reef friendly and organic. They are pricey but my skin appreciates the extra!

Works like a charm
Size: 7 Fl Oz (Pack of 1), Style: SPF 30
Easy to apply. No heavy scent. I'm very pale and am able to have fun in the sun without burning.
