This is one of those super breathable work out or sports shirts. Think Under Armour, but with merino wool in it. I got the black / silver version.

It's super thin and has perforation on the sides. I'm sitting here at the computer and can already feel how breathable it is. It has a combination of merino wool and 3% Lycra.

I'm 5'9" and 150 lbs and purchased a size medium. I would not under any circumstances downsize at all. The fit is super precise. The sleeves end at just where my wrists are. In fact, if I was more muscular I'd suggest upsizing.

I got this on SAC for $40. OK buy. Great for general layering or going to the gym.

I got the Twister gray version of this. It's nice and quite weighty, however, the fit is unorthodox.

The width of the body is wider than normal, yet the waist is short. The arms are ridiculously wide. Why?

I thought this would've been perfect as a standalone sweater for the night out, but the cut makes it look too awkward.

I guess this would only be suitable as a heavyweight underwear piece. It is not snug at all and doesn't look as good as my other Icereaker pieces.

Good durability, poor fit.

This thing looks way better in real life than what the pics display. I got the Stealth colour, which is a super subtle navy with perfectly blended striping on the front. It's a high quality, super convenient and practical hoody. I'm 5'9", 150 lbs and I got the medium; the arms' length is perfect, but the waist is just maybe a little short if I wanted extra coverage over my jeans. Also, the wrists are too loose and not resilient enough -- If you've ever owned a cheap cotton long sleeve t-shirt, you'll know what I mean when I say the wrists will eventually get looser and looser. It feels the same with the Eclipse hoody. In the end however, this piece is pretty much perfect for everyday street wear or layering.

I got this on SAC for $65 which is an excellent price. The full $140 original price would've been too steep for me in my opinion.

Here are some other points that might help you make your purchase:
- There are no thumb loops
- There are no drawstrings for the hood
- The waist might be a little short (although it's extremely minimal & based on personal preference)
- Made in China

I'll be keeping this one for sure. A very good looking piece.

This is a quality made bag. It is perfect size for weekend excursions or 1 week long travels.

There is a large main compartment inside, a large outer pocket (perfect for shoes or sandals), a water hydration pocket (which is right behind the back), 2 small waist/hip pockets on the waist belt (which are too small for any practical uses -- but they might be good for holding candy wrappings?), 2 side pockets (right by the compression straps) which are ideal for water bottles, 2 stretch woven pockets on the shoulder straps (which look like they're perfect for placing small cell phones), a removable top pocket with internal stash pocket, a plethora of bungee and additional tie-off points, sleeping bag straps (which are at the bottom), and a zippered lower section which allows you access to the bottom inside of the pack without having to rummage through the top.

The pack looks great aesthetically (I got the Moonlight Blue version and I've already rec'd compliments from my mom and sister) and is functional. HOWEVER, I'm skeptical about the durability of this pack. The plastic buckles seem very minimal and thin, and I'm afraid to go hard on them. The stretch woven "cell phone" pockets on the shoulder straps also feel like they're going to wear holes through them over time. Most importantly the fabric of the bag seems quite thin as well.

With that being said, I highly suggest not using this bag for any type of airport or overseas travels, where the bag might be subjected to harsh throws and frictional abrasions. This bag is only ideal for fast, on-the-go weekend or week-long trips and shouldn't be used and/or relied upon as a durable travelers bag, because it simply isn't designed to be. I would get something from Osprey's Travel Series if you're planning on using your bags for more rigorous purposes. The foam (such as on the shoulder straps and hip belt) is also much thinner than I had expected before it arrived.

Otherwise this Talon 44 is very lightweight (2lbs 7oz) and perfect for short term, personal trips. Also, I am 5'9" and weigh about 150lbs: I got the size M/L 2600 cu inches (44L) one and it fits very good. I got this bag on sale, but I would only pay full price for it if it was more durable.
