I'll be riding 3000km this summer and needed a non sweaty, breathable, non smelly cycle top. And isobaa meets all those requirements
Finally a cycling jersey that’s not smelly lycra that I can also wear on utility rides/around town and not shouti “she’s riding a bike”
Just tested on a month long camper van tour in Spain/France. Didn’t wear any of my other jerseys on mtb and road/gravel bike rides of varying lengths. Swam in it one day after a ride otherwise just aired out. . Canicule weather.
Back pocket could do with reinforcing at the bottom with some tape, as phone drags it down, it might wear through..
PLEASE bring out a long sleeve version, I burn badly and hate wearing separate arm uv protectors. Material is perfect for hot weather and for layering in more inclement (normal) cycling temps.
I sized up to L, my other isobaaa Ts are M Very long I’m 1.6m happy with the (intended) looser fit.
Really lovely cycling top, Good fit, and nice colour (petrol). I'm 1,75, 80 waist, 106 measurements and an an athletic 63years old, I bought a M, which is a great fit: Good length, close fit without clinging, useful pockets and zip neck. The only downside for me is that I live in Spain, where temperatures can soar, and I find the cloth quite thick, not as light as I would personally like. I wouldn't mind on a long sleeved garment for the cool months, but for a short sleeve I'd prefer a lighter weight merino. It might be fine in the U.K for instance. But, a nicely designed top, and not too tight, f(or a change with women's cycling clothes). Recommended.
Wore on a bikepacking trip - comfortable, breathable, didn't smell. New favourite biking tee.
I love merino clothing and have been lookibg for a merino cycle top. Search no longer. This top is brilliant. Excellent sizing, slim fit but with excellent length. Very comfortable while cycling and washes well and dries quickly. Would like some brighter colours to choose from for my second cycle top purchase. Otherwise very happy customer :-)
