Insulating Layer help

Since you have time before the trip, start checking around at thrift stores. You could get very lucky and save a lot of $.

Define “very affordable.” Like, a max dollar amount. $20? $100? $200?

If he can find something in the $100 range that would be nice, but I am willing to pitch in another $100 for a birthday gift.  I’d say no more than $200, so not looking at Patagonia or Arc’teryx currently.

The Enlightened Equipment Torrid is a good buy at $185. It is very light and pretty warm. Say, summer nights in the alpine and shoulder season down to freezing with some other layers. I’ve used one for 2 years now and am very happy with it. I have a closet full of other super high-end puffies, but it still goes on most trips.

For $200, Montbell has some down options.

I concur on the Torrid recommendation.  I have two Nunatak versions (one warmer and longer than the other) but also bought a Torrid for my son and have recommended it to my daughter for similar application.  Down has its advantages as well, but a good quality warm down jacket probably doesn’t fit your price range unless you find a good deal on a used one.

I love my Costco Triple Star Down Parka–tons of loft and warmth, ultralight, highly compressible, very silky fabric, and purchased new for $30. They are discontinued now, but frequently show up on eBay, and you might be able to find one here on Gear Swap since they were popular here 10 years ago. This thread talks about sizing (doesn’t work for big and tall folks). Good luck.

REI garage sale sent me a notice a day or two ago advertising “70% off”. Rei also has a used gear area on line.

I also used the Torrid on my JMT hike this summer. Last time I used a Rab that was more expensive – $200 – and it was a lot warmer. But I don’t need the warmth at the temperatures you describe. I endorse thrift shopping; it’s incredible what you can find in near perfect condition for 1/4 the cost.

Look around for used or returned.

I picked up an REI magma hooded, 850 down jacket yesterday for $83.00
It had a nick near the wrist and one piece of down was poking out, looked new otherwise. It was on the garage sale rack.

I see down jackets around used or on sale frequently.

The Decathlon Trek 100 weighs around 10oz, has 3oz of 800 fill power down and costs $80.

Take a look at Uniqlo.

I picked up an REI flash jacket and an REI magma jacket off the garage sale rack for around $50 each. The racks are in store and open daily now so picking a weekday can be pretty effective. (I work by an REI so compulsive even)

Facebook marketplace can be really good if you know exactly what you want and what you should pay.

If used is acceptable the LL Bean Ultralight 850 is good value for money. Although total weight at ~13oz  is heavier than the Ghost Whisperer, it’s filled with 3.5 oz of down vs 3 oz in the GW. So could be a better option for someone who runs cold.

@andrew used is absolutely acceptable.

I really like my Montbell UL Thermawrap Jacket. Montbell markets it as an active insulation piece, which is why I picked it up. But I was surprisingly comfortable sitting on a ski lift with merino base layer + alpha direct + Thermawrap + Versalite in 10-15F temps. It’s 8.5 oz, and ~$95 ordered from Japan, $179 from the US site.

To get the most warmth, I’d want to make sure to have a windproof shell. You could also upgrade to the parka, which has a hood.
