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.

Runs way too small
Color: Black, Size: Medium
If you live in the U.S. and wear medium, a large will fill you perfectly. I wear large and the “large” is objectively a medium in the chest arms and neck. Fix your sizes.

Looks Sharp! Stiff, Balloon Comfort!
Color: Black, Size: XX-Large
I purchased the PJ PAUL JONES Men's Oxford Button-Down Shirt as a gift, and it comes with a mix of strengths and trade-offs. The buttons are plentiful and high quality, and the inclusion of a couple of spare buttons is a thoughtful touch. The color is a deep, rich shade just as I hoped, giving the shirt a sharp, professional appearance. The fabric has a noticeable texture that looks like cotton, but the heavier thread count gives it a sturdier, more rugged feel, (almost outdoorsy) rather than the soft, premium cotton I expected. My biggest concern is that it may feel scratchy against the skin and less comfortable for long hours of wear. The shirt is also quite boxy in shape, with little to no side curve, which limits ease of movement and can cause it to crease or untuck when bending or sitting. Overall, it’s a durable, well-constructed shirt with a polished look, but comfort and fit may be an issue if you prefer softer fabric and a more tailored, flexible cut.
