It has a wide hood that can accommodate other hoods below it, although it was designed for helmets. It is slightly more compact than the Testa Softshell 5 jacket. I can fold the aptus up quite well and stick it into my tenzing pack. The side pockets have a deeper well, so things won't fall out sideways as easily. It has the heart outside pocket, which is great.
The winter camo finish looks very nice.
The fleece lining reminds me of how honey comb blankets are, except instead of trapping heat in the pockets, the circles allows heat to transfer between the layers. I wore it over a L3 lochi reversible. I am 5 8 ish, 170-185 lb, with thin bone structures. The L3 lochi fits with an M, barely, around the shoulders, and somewhat tight on the lower back and belly. The Aptus I got was L sized, so easily fits over the L3. I felt no mobility constriction as a martial artist and massage worker, except at the elbows which prevented full contraction via the biceps.
It is slightly heavier than the L3 Lochie, about the same weight as the Testa Softshell, but is less bulky than the Testa Softshell 5 due to the compactness. Temperatures in GA now a days is 29 low 50 high, and it felt great during the evening and morning. During noon, unzipping both layers to mid solar plexus works to ventilate. I don't wear the Aptus as the second layer only, especially since my first layer is a summer shirt, since it doesn't trap the heat next to the body. It works better as an outer third or 4th layer.
I've bought a few pieces of Beyond's clothing line and they are quite well designed. Even the sleeve pockets have a use, although perhaps not the way they intended it. I put crystals and potential armor into the pockets. Anti cut gloves can be stashed there, to be used later, or even just to protect your bicep in a martial conflict. Cloth armor was often used as a base layer back in the ancient days.
