Simple and durable, yet refined, your perfect companion for uncomplicated summer adventures.

The Treeline Sleeping Bag is a budget-down bag that is ideal for three-season use when you’re confident the temperature won’t drop far below freezing.

 

This bag is a relaxed mummy shape, with extra space around the hips and shoulders and a fitted hood to keep your head snug. With a 2°C comfort rating and a -3° lower limit, the Treeline is perfect for three-season use when conditions won’t dip below freezing. The outer shell and lining are made from 50D nylon, which makes it durable enough to take camping with the kids and even the dog. The fill is comprised of 400g of compressible R.D.S certified lofty 600+ down for warmth, and it has a two-way YKK #5 side zip with an anti-snag system so you can ventilate on balmy nights.

Heat won’t escape through the zipper as there’s a draft tube to prevent that, and you can pop your phone or other essentials in the internal chest pocket. If you’re in need of a wallet-friendly down bag for three-season adventures – the Treeline Sleeping Bag from Sea to Summit is the one for you.

Looks exactly as pictured
Color: Gold
Bought this as a graduation gift for a sons friend who admired a similar one on vacation with us. He really liked it and it is a nice entry level dress watch for those who like to collect them. It was easy to adjust the band with a personal watch kit and was heavier than I expected.

Simple, elegant, versatile
Premium quality at a reasonable price. Simple and elegant. I have yet to wear this watch without receiving multiple compliments, even in sweatpants on my way to the gym. I took it to a high-end jewelry store to have some links removed, the master jeweler there immediately commented on the quality of the movement and what an underrated watch Tissot makes. (Mind you, he had a table full of Rolexes, AP's and Pateks that he was working on) Very comfortable to wear, heavy enough to feel it on your wrist and light enough where it doesnt not become cumbersome.
